Sea and shore birds, and their habitat across the West Coast Te Tai Poutini, are healthy and thriving.
Our Mission is to achieve this through research, education, awareness, advocacy and practical projects, founded on strong science.
Penguins and other seabirds are a treasure or taonga, and we strive to protect and conserve them and their habitat – the wider marine and coastal environment.
Birds We Protect
Your donation will be doubled to help us do more for West Coast penguins
Your donation, matched by a generous supporter, will help us understand and respond to threats to West Coast penguins.Starting right this minute, we are very excited to share this opportunity with you. A very generous donor has offered to match donations up to $5000! With your help, we can reach $10,000 in donations in the coming weeks.
And we need you to make it happen!Your donation will firstly ensure we monitor penguins, both little blue penguins - kororā, and Fiordland crested penguins - tawaki. The data we collect is critical in informing what actions we can take, so your donation will also help ensure we take the next steps, whether building penguin protection fences, working with school children or liaising with councils and developers for example. We know that you will feel good about supporting a cause you believe in and value - the work that we do and the penguins we all love. But did you know that science confirms that? I like to call it the 'joy of giving' and it turns out others call it that too. Some of the benefits - and joy - of making a donation, small or large, include a greater sense of community and a sense of purpose and fulfilment, a greater happiness and satisfaction, feelings of gratitude, an improved outlook on life and boost your mood! I have even read that giving lowers levels of inflation!
How to make a donationThere are a few ways you can donate and feel the warmth and joy of giving for penguin conservation. Easiest is via our donation page using a credit card - bish, bash, bosh - thank you! You can also go there to make a donation in memory of someone special. Also easy is a direct bank payment donation. We just ask that you also email us so we can thank you and send you a receipt. Whether credit card or bank payment, you can of course make it a regular donation if you'd like to keep that joy going! There are donation boxes at New World and J's cafe in Westport and in Hokitika at Moment's in Time/NZ Post, Hokitika Craft Gallery, and the Kiwi Centre. (Any suggestions for a location in Greymouth gratefully received!) And you could use any of these to make a donation on behalf of someone as a gift, Christmas or otherwise. We have a couple of cards you can print out to let them know. Download - Christmas Penguin - donation in lieu of gift card Download - Penguin love donation in lieu of gift card
Westland petrel/tāiko – be on the lookout!
Westland Petrel/Tāiko chicks fledge from November to January. Their first flight can be a tough one, as they are inexperienced fliers, and can become disorientated by bright lights and poor weather conditions. Adult birds are also found at any time of year.
Westland Petrel/Tāiko chicks fledge between November to January from their colony just south of Punakaiki. Their first flight can be a tough one, as they are inexperienced fliers, and can become disorientated by bright lights and poor weather conditions. Adult birds are also found at any time of year.Once on the ground they need our help, as they are unable to take flight again easily, and are very vulnerable to being struck by cars and attacked by dogs. The main flight path area for these birds at the northern end of the Barrytown flats has no street lights, which is great for the birds ordinarily but means that they may be distracted by vehicle lights and come down on the highway. These large all black birds are then almost invisible against the black tarmac until the next car comes speeding along. If you're driving in the area, please be mindful of these birds particularly November to January, and travel a little slower. The same applies in all coastal areas where penguins could be crossing too - better for wildlife, safer for you, and less fuel used - win - win - win. The Department of Conservation and Westland Petrel Conservation Trust work together to help these birds get back out to the sea, and document when/where all birds are found, so we can work to remove attractive lights sources or hazards. Particularly around Punakaiki and Barrytown but in fact anywhere between Hokitika and Westport, there are a few things you can do to help reduce the risk to this special bird, which only breeds in one place in the world. To give them the best chance of success:
- Avoid leaving bright outdoor lights on after dark and close curtains and blinds, as this confuses them
- Keep dog(s) secure at home
- Keep a cardboard box, with air holes and towel in your car, just in case!
- Use a towel (or item of clothing) to cover the bird and gently lift it into a box (unwrap the bird once in the box), or move it away from danger (traffic).
- If you feel uncomfortable handling the bird or require assistance, please immediately call the numbers provided.
- Birds found can be transported to the “Petrel Drop Off Boxes” at the DOC Visitor Centre (if the centre is closed go through the gate to the left of the front door).
- If you are unable to transport the bird please call the numbers provided.
- Please do not attempt to release the bird yourself.

Trust’s 2022-23 Annual Report
Our annual report always includes a message from the Trust Chair, the highlights and challenges of the previous year and our enormous thanks to all those organisations and individuals who have supported our work.Our annual report always includes a message from the Trust Chair, the highlights and challenges of the previous year and our enormous thanks to all those organisations and individuals who have supported our work. This year, our Chair, Robin Long, reinforces our vision - sea and shore birds and their habitat across the West Coast Te Tai Poutini are healthy and thriving - highlights the funding challenges, and embraces the changes over the year. We report on our various projects and, for little penguins or kororā, this meant a poor season apparently linked to a severe cycle of La Niña conditions and the marine heatwaves that it brought last spring and summer. The little penguin mortality database we share with the Department of Conservation has been invaluable in focussing attention on the key threats to these birds. We have now worked on the data so that it can be viewed on maps providing even more value to our advocacy role and for council planners. It also helps focus our attention on areas where extra action may be needed, perhaps new penguin protection fences. Speaking of fences, we were very pleased to add fencing in the Limestone Creek area north of Punakaiki and will need to add more fencing between breeding seasons in the next couple of years to completely protect kororā in this section of the coast road. The report is available as a PDF via the link below, with updates on our Fiordland crested penguin / tawaki work, Cape Foulwind and Seal Island trapping projects, a note about our favourite petrel, the Westland petrel or tāiko, our education programme - much treasured by all the teachers and staff that get to work with Ranger Lucy Waller, and our awareness and advocacy work. We are so grateful to our donors and sponsors all year round but this is our annual opportunity to put it in writing where everyone can see it. Our heartfelt and huge thanks go to these wonderful individuals and organisations that enable us to help understand and better protect penguins and seabirds.
Education plays a key part in the West Coast Penguin Trust’s activities. We are welcomed into schools, armed with Kevin the taxidermy Kororā and Toni the Tawaki (fiordland crested penguin; the South Island West Coast’s second resident penguin). We visit schools and educate the students about penguins, thus encouraging discussions about the environment and conservation issues. It is never a difficult mission to get the students, and staff we should add, to fall in love with penguins, excited to find out that they have these wonderful creatures on their local beaches and then devastated to find out the struggle of survival they face due to humans! Using our Blue Penguins & Other Seabirds resource book, which links games and activities throughout the entire curriculum, fitting into any subject, the schools get involved in activities to learn lots of facts and then moving on to learning how to become the ‘Guardians of their penguin’ and taking the message home to their local communities.Education plays a key part in the West Coast Penguin Trust’s activities.

Many schools have gone on to being involved in penguin projects where they have built nest boxes for local colonies, set up trapping lines and monitored and observed local beaches, carried out beach clean ups and raised awareness in the community with newspaper articles, leaflets and presentations. The school projects are invaluable and we are always very grateful for all the hard work and enthusiasm that goes into these projects.
Penguin and Seabird Educational Resource - now in second editionThe Trust has developed a penguin and seabird education resource aligned to the NZ Curriculum especially for the West Coast but it will be of value for educators and children everywhere, particularly coastal areas of New Zealand, and whether at school, home or youth group. The resource has recently been updated and improved and you can down load it and/or request a hard copy (scroll down for details.) “Blue Penguins & Other Seabirds. Activities for exploration and action for schools and community groups” is aimed at children in the age range 5 to 9 but can be adapted for younger or older children. The goal is for local people to learn about and take action for the wildlife in their own back yard. Research has also shown that children gain essential values for the environment and a lifelong connectedness to nature in this age group. Fun learning activities are included within the education resource, including games and arts and crafts. With all the resources on line, they are readily available to home school parents and students and indeed anyone with an interest in sharing a love for and interest in the coastal environment with children. The project focuses on blue penguins but includes sooty shearwaters (both species are in Gradual Decline, 2005 NZ Threat Classification System), Fiordland Crested Penguins or Tawaki (Nationally Endangered) and Westland Petrels (Range Restricted), all in their natural habitat. The coastal habitat of these species on the West Coast has, as it has around NZ, been modified or disturbed by humans and their activities. We welcome any feedback on the resource and we would also love to receive photographs and stories as you have a go at the various activities. Please send them to us at firstname.lastname@example.org.

Fiordland crested penguin predator study
In order to understand whether and if so which predators were contributing to an apparent decline in the numbers of Fiordland crested penguins, the West Coast Penguin Trust embarked on a study using trail cameras in 2014.In order to understand whether and if so which predators were contributing to an apparent decline in the numbers of Fiordland crested penguins, the West Coast Penguin Trust embarked on a four year study using trail cameras in 2014. For the 2019 season, which followed a 'mega-mast' seed event and predicted rat and subsequently stoat population explosions, the Trust established an annual breeding success monitoring programme. In 2020, following a mega mast in Autumn 2019, the Trust has extended the project, with the support of Wellington Zoo and the Birds New Zealand Research Fund, with the aim of better understanding whether breeding success is adversely affected by the presence of stoats, and if so, what is the best means to manage that threat. An overview of the work planned for the 2020 season is available on the Birds NZ website and a summary of the 2019-2020 seasons is here and the full report here. There were many fewer stoats than expected and predation was low, which was great for the penguins and showed us that there is plenty more to learn about the relationship between beech mast events, stoat populations and predation. (Interim reports on the 2020 season can be found here (March) and here (June).) The Trust's Tawaki Ranger and Trustee, Robin Long, gave this TED type talk in Franz Josef in October 2019, summing up the Trust's work and her experience of tawaki both at home in Gorge River and volunteering with The Tawaki Project. Robin has continued her adventures to survey areas of Stewart Island with a survey of the Port Pegasus coast in September 2020. A report of her mission can be found here. Project Background The Fiordland crested penguin, or tawaki, is in need of our help, being listed as Nationally Vulnerable and one of the least studied and rarest penguins. Tawaki is the only crested penguin to inhabit the main islands and coasts of New Zealand. The 2012 IUCN red list classifies them as Vulnerable. The West Coast Penguin Trust ensures that conservation management is based on good science. Introduction The Trust has set out to establish which predators may be contributing to a decline in the population so that appropriate targeted action can be taken. This follows a technical review of the conservation status of both the species and earlier management actions and a priority action was to determine the effects of introduced predators on the breeding success of tawaki. A funding bid for a pre-predator control project to the Department of Conservation in 2014 was successful and motion activated cameras were purchased with sponsorship from local businessman, Geoff Robson of Greenstone Helicopters. Cameras are a low impact method of obtaining the information and these were installed at two colonies at Jackson Head and Gorge River in South Westland, in late August for the four breeding seasons 2014-2017. This work will ensure that any predator control targets the appropriate species in the most effective way, thus saving money and contributing to the conservation of the species in the longer term. Four-year study Our study coincided with a five-year study into the ecology and particularly the foraging ecology of tawaki by Dr Thomas Mattern and The Tawaki Project. We were able to share both resources and findings and the projects complemented each other extremely well at the Jackson Head site. In the second year of the study, 2015, El Niño conditions off the West Coast resulted in almost complete nest failure at Jackson Head as chicks starved and adults swam up to 100km for little food and poor nutrition. In the third year, 2016, stoats, which had been scarce, appeared in large number at the Jackson Head site and both eggs and chicks were lost to predation. A fourth year in 2017 found breeding back to 'normal' levels, without El Niño conditions and with barely any stoats visible on camera footage. Link to study report after 2017 season With two abnormal years in the four-year study, but it appears that the large numbers of stoats and the loss of chicks was a direct result of an earlier beech seed mast event close by. These events, when trees produce massive amounts of seed every 2- 6 years, result in explosions in mice and rat populations, followed by stoats. As the food source for stoats runs out - as the seeds rot and germinate and rodent numbers reduce - stoats are likely to spread out in search of food. We believe they spread to Jackson Head in 2016. The report at the end of the fourth year is here: WCPT Tawaki report 2018 Final Shift of focus from predators to breeding success while assessing presence of stoats Stoats are clearly the main land-based predator of and threat to tawaki in South Westland although only in some years when stoat numbers are in plague proportions, apparently or likely linked to mast events. The Trust has shared its findings with the Department of Conservation and is recommending that landscape predator control operations be managed to take tawaki into account. They have traditionally been focused on species such as kaka and mohua, and ensuring tawaki nesting areas are included is a tiny step to take as treatment areas are already including or could include such colonies. In order to gain a better understanding of the situation, the Trust started an annual breeding success survey of nests in the three areas of our study in the 2019 season and, in addition for the 2020 season, carried out trail camera and tracking tunnel monitoring (overview here). A variety of both research and management priorities have been identified for tawaki and the West Coast Penguin Trust is involved in progressing those priorities for the benefit of the species, working with both the NZ Penguin Initiative and The Tawaki Project. Have a look at The Tawaki Project site for up to date blogs and news of their project, now focused in Milford Sound and check out http://pengu.cam/ for some extraordinary video footage, recorded under water from the back of a penguin. In 2019, the Trust focussed on two colonies while the NZ Penguin Initiative did some intensive monitoring at Jackson Head. Read their report in the NZ_Penguin_initiative_ReportQ1_2020.pdf where they expected an invasion by stoats following the major mast event in summer 2018/19, but which did not eventuate. A 2021 tawaki season report - WCPT has been summarised by Trust Ranger, Linden Brown. Find a report on the 2022 tawaki season here. A review of all three seasons monitored for breeding success and stoat presence (2019- 2021) to date can be found here. The summary is as follows:
- Tawaki nests were monitored at three distinct colonies in South Westland for three years
- The aim was to determine breeding success at these colonies; determine if there were any trends year to year, or between the colonies; and to better understand the link between mast events and stoat populations and predation as well as to methods of predator control.
- Trail cameras and tracking tunnels were used to determine the presence of predators (especially stoats) within the colonies.
- Breeding success was high at all three colonies for all three years, with no obvious differences or trends between years or between colonies.
- Stoats were present at all three colonies at different times, however at low numbers, and are likely responsible for a few tawaki nest failures.
- The mast event of 2018-19 did not result in any observable increase in stoat numbers in the colonies in either the 2019 or 2020 seasons
- Lack of food did not appear to be an issue for breeding tawaki during the study period.
Blue Penguins – monitor and review
The Trust started life in 2004 as the Blue Penguin Group, a group of concerned residents in the Greymouth/Charleston area who had noticed that blue penguin numbers were declining. The Trust has been monitoring penguin breeding success in a number of colonies ever since and using the lessons leaned to improve conservation management for these penguins on the West Coast.
Science is at the heart of our workUnder the direction of former Lincoln University ecologist, Trust Scientist and former Chair, Kerry-Jayne Wilson MNZM, science underlies all the the Trust does. The Trust began by determining the role of stoat predation on the apparent decline of blue penguins in the Buller area. Stoat traplines were established around three colonies, while two others were left un-trapped, and then nests were monitored for breeding success. After five years, it was clear that the breeding success was not improved by stoat trapping and just a couple of incidents of predation by a stoat were recorded. At the same time, working with the Department of Conservation, a blue penguin mortality database was established. This showed that the vast majority of dead blue penguins reported to the Trust or to DOC, around 60-70% depending on location, were being killed on roads close to the coast. The second largest killer of penguins on land was dogs. This was compelling evidence to focus our efforts on preventing penguins being killed on the roads and by dogs. Read more about the penguin protection fence project here. Ensuring that penguins are safe from dogs is an on-going challenge, one that the Trust has attempted to address in a variety of ways, and work is continuing in collaboration with the Department of Conservation and the three District Councils. In the meantime, monitoring of penguin colonies was expanded to include other sites in the Buller area and we now maintain the monitoring of two colonies on a fortnightly basis throughout the breeding season and twice yearly for the other colonies. Long term data is invaluable for improved understanding of the species and could alert us to major issues.
BurrowscopesMonitoring is undertaken using burrowscopes. These are small cameras on the end of a 2m flexible tube, sending images back to a monitor. The camera can be gently inserted into a burrow, often quite deep underground, to establish whether eggs or chicks are present with minimal disturbance for the penguins. In addition to the Buller monitoring, the Trust has carried out surveys of Okarito penguins in 2008, 2013 and again in October 2018. The colony south of Okarito is generally well away from human disturbance and numbers appear to be steady.
What's happening nowMasters student Luisa Salis-Soglio is currently reviewing all the data monitoring date to and including 2019, aiming to establish any trends, as well as any links to knowledge of foraging patterns established through our GPS study. After a disappointing breeding season in 2019 with chicks lost to starvation, the 2020 season was been far better, with breeding success at 66.7% at one site (numbers of chicks fledged from eggs laid) and an excellent 89.6% at the other. The 2021 breeding season was outstanding, with chicks fledging from 82% and 93% of eggs laid from the two colonies monitored fortnightly. Read about the 2021 season here. Sadly, the 2022 season was again a poor one, with chicks fledging from only 35% of eggs laid. Read a season report here.
Nest box designIn areas where weka are present, they will try to predate penguin chicks. Nest box design is critical and we have provided a design that aims to minimise the risk of predation by weka. Read more and find the design here.
Cape Foulwind and Wall Island
Cape Foulwind is a wonderful place to visit at any time and we're hoping to add to that experience by carrying out predator control for sooty shearwaters. 'Sooties' can be seen between November and May as they fly back to their burrows over the wooden section of Cape Foulwind Walkway.
Sooty Shearwaters / TitīAlthough the population of sooty shearwaters is in the millions, they are in decline, surviving on islands, particularly around the southern South Island. A handful of 'sooties' nest on the mainland at Cape Foulwind and the Trust has been encouraging more to nest here and trying to protect those that do with trapping. Over the past few years, numbers nesting at this site have increased, but the colony remains small and as yet no chicks have fledged. With more frequent monitoring and using trail cameras in the 2022 season, we learned that weka may be responsible for taking chicks immediately after hatching. These large black birds are consummate seabirds, flying up to 2000 km from home on foraging trips and have been recorded diving more than 60 m. They return to their nests around dusk, so simply standing on the Wall Island lookout of the Cape Foulwind Walkway should reward you with the sight of these birds during their breeding season, from November to around May. They are usually silent at sea; most calls are given by birds at night on the breeding colonies, though occasional calls are given by birds flying over breeding colonies at night. The main call is a loud, rhythmically repeated slightly hysterical coo-roo-ah generally made by duetting birds from within burrows or on the surface. Here's a video of a noisy pair of 'sooties' at Cape Foulwind.
Little Penguins / KororāThere are only a few blue penguins nesting at Cape Foulwind, despite the sound system mentioned above also being used to play calls to encourage them into this site. These sounds are played between June and August, as the breeding season gets underway. In time, the Trust hopes to establish a small viewing opportunity, perhaps with a discrete nest cam.
Fairy Prions / Titī wainuiFairy prions are beautiful small petrels, also known as dove prions as they are pale grey blue in colour. Only 25cm long, they are very vulnerable to prolonged stormy weather, often succumbing and being washed up on west coast beaches in vast numbers. The Trust discovered that Wall Island, the rocky island some 250m off shore from the Cape Foulwind seal colony, has more seabirds than any other island between Cook Strait and Stewart Island. Every scrap of soil on this rocky outcrop has been used for a seabird burrow, predominantly fairy prions. The island is currently predator free, and the Trust maintains the trap line on the nearby coast to ensure it remains that way. We also check the island every couple of years or so to ensure that prions are surviving. Any presence of predators would mean that the prion population would crash.
West Coast Blue Penguin Count
An annual count of blue penguin sign on West Coast beaches in October, but we'd love to hear from you anytime. It's a great opportunity to discover your beach and to be involved in a project!Click here for the 2022 Blue Penguin Count Form This is an annual event in spring, but we invite observations at any time of year. Are there penguins on your local beach? We’d love you to find out and let us know! An early morning walk in the spring will help you rediscover the beauty of your local coastline, discover whether penguins are using the beach and help us build a clearer picture of where blue penguins are on the West Coast. We have selected these dates when the tide will be low early in the morning to keep you safe and to offer the best chance of seeing penguin tracks crossing the freshly washed sand. You can add your observations any time, but always pay special attention to tide times and conditions.
Let's get back to paper and pencil this year! Here's a simple form: 2022 blue penguin count form to print and take with you or take some paper and note the key observations. And then share your results with us in one of the following ways:
- ideally add your findings to our super simple Google Form, or
- you can photograph or scan your form and email to us, or
- add the details direct to an email, or
- post the form to us c/o 231 Revell Street, Hokitika 7810.
Using i-Naturalist To make it even more useful and accurate for us, penguin observations – probably mostly penguin tracks but perhaps a live penguin or penguin sounds – can be recorded using the i-Naturalist app on your smart phone or tablet, not only this week, when blue penguins are likely to be busy feeding chicks and the tides are just right, but any time that you come across them. iNaturalist has been around for a few years, is ‘the online place for Kiwi nature watchers’, and you can add any nature observation at any time. It may take a few minutes to install and familiarise yourself with it, but then it’s a piece of cake to add your records, including your photos if you wish. At home, create a login and then find The Great Annual Blue Penguin Count under ‘Projects’, and join our project. Link to the Great Blue Penguin Count October 2022 project Then, click on ‘Add Observations’ and start entering your record or records! You just zoom into the map and click on the location of the observation and add details, comments and photos following the prompts. For your mobile devices, open the iNaturalist webpage, scroll to the bottom of the page and get the Android or iphone app or find the iNaturalist app in your app store. Then the same applies – create a login if you haven’t already, find and join our project, and then record your observation. Enable GPS so that the app finds your location, then you can add a note, a photo if you wish and the few details for our project and move on to the next observation, perhaps more penguin tracks, as you walk along the beach. HANDY TIP From previous experience, where there are lots of tracks, or even just a few, it’s simplest to open the app on your phone or tablet, ensure GPS is enabled, then record each observation as you see it, with or without a photo, then, back at home, open iNaturalist on your computer, go to “Your observations” and then click on the “Batch edit” button. You then tick all the observations you have just made and complete the fields for each in one go, e.g. penguin tracks or live penguin etc, rather than entering them as you go. Saves heaps of time and effort! You can also look at our project to see where others have recorded observations. There is plenty of help in the iNaturalist help section, so give it a go – have a play and use it for penguin tracks for us, but also native birds, spiders, fungi, plants ...! And don’t forget, iNaturalist is for all nature observations, so you can add other encounters, perhaps oystercatchers, dotterels, shags, seals, skinks, or a curious fungus or seashell any time! I added what I thought was a washed up small ray, and it was subsequently identified as a New Zealand Rough Skate. Have fun!
GPS Foraging Study of Little Penguins – Kororā
The Trust had focused on establishing and addressing the land based threats to blue penguins for several years and, in the last few years, has sought to understand the marine ecology.Tiny GPS units were applied to little / blue penguins during the 2015, 2016 and 2017 chick rearing seasons and the Trust collaborated with the Museum of New Zealand Te Papa Tongarewa in a wider study to better understand the foraging patterns that were discovered. A report was published in the NZ Journal of Zoology in April 2017, led by Tim Poupart and Dr Susan Waugh of the Museum of New Zealand Te Papa Tongarewa, and included data from three sites, Wellington, Motuara Island (Marlborough) and our West Coast study. Data has been collected for five years and, for three of those years, the West Coast Penguin Trust carried out the field work at Charleston and Cape Foulwind. Altogether the study includes tracks gathered on 68 individuals in three regions of central New Zealand between 2011 and 2016. Foraging patterns varied between sites and between years. Tracks revealed that penguins can rely on distant foraging areas while incubating, with nesting birds from Motuara Island travelling up to 214 km to feed. Isotope analyses of blood samples showed that this distant food from deep waters (0–200 m deep) is likely to be squid dominated, which has a low nutrition value. During the chick rearing period, birds undertook a diet shift to a higher trophic level while foraging closer to their colony, and possibly near river plumes. These findings highlight the need to consider much larger potential foraging ranges when assessing and managing threats to the penguins. The research team, including the Trust’s Kerry-Jayne Wilson and Reuben Lane, advise that conservation efforts need to take this variation into account to protect these penguins, which are currently in decline across New Zealand. The Trust continued the project in 2019 with the support of the New Zealand Penguin Initiative. The NZPI was able to supply GPS trackers that also measured dive depths and although only two tracks were obtained, the information was very interesting and useful. Read more here. The study continued in 2020 with greater success and 11 tracks obtained illustrated below. After a gap in 2021 due to ranger changes, hopes to continue and expand the foraging study during the 2022 season were abandoned due to the obvious stress being experienced by the penguins due to the marine heatwave. It was picked up again for the 2023 season with new Ranger, Lucy Waller, and focused on the early chick stage when adults would be taking turns to forage and feed the chicks. The Camerons colony was used for the study this year and the six tracks obtained indicate a similar pattern to earlier results from the Charleston colonies, in terms of direction and distance, but more detailed analysis is required, including of the depths of dives also recorded on the loggers. We are very grateful to the Brian Mason Trust and the Lottery - Environment & Heritage Fund, for their support for this project this and next season. We expect additional analysis of foraging areas in relation to other marine influences including currents, climate events and commercial fishing, to follow at some point, and for now, we'll be focusing on ensuring consistency of process to collect data annually and contribute to an understanding of the foraging activity of blue penguins on the West Coast through the four key stages of the annual life cycle, namely incubation, chick rearing, pre and post moult. We’d like to thank the JS Watson Trust (managed by Forest & Bird) for their support, Te Papa for their collaboration, and Dr Thomas Mattern for generous help, guidance and expertise.
Pahautane Penguin Fence
3000m of fencing to protect penguins and prevent them being killed on SH6 - The Coast Road. It's saving the lives of several penguins every year and mortality has reduced to zero in these areas.Why build a penguin fence? Where the Coast Road is close to the sea, penguins may choose to nest on the ‘wrong’ side of the road. Both parents will feed penguin chicks and they often go to sea to forage every day, leaving around dawn and returning after dark. These small birds don’t stand a chance against vehicles and large numbers of birds have been killed on some sections of the road. A fence on the sea side of the road was the obvious solution as it restricts the penguins to nesting habitat below the road, preventing them nesting and therefore crossing to the other side of the road. Why build it here? The West Coast Penguin Trust has been recording penguin mortality since its inception in 2006. A few sites along the Coast Road have been found to be hotspots for road kill. Three locations on the Coast Road (SH6) have claimed the lives of over 100 penguins in five years. They are the McCarthy Creek area, the south side of the Fox River Bridge, and Pahautane Beach to Hatters Bay. The annual penguin census, along with scientific studies, suggest that blue penguin numbers on the West Coast are continuing to decline. In March 2012, the Trust and Conservation Volunteers erected a trial 100 metre long penguin fence south of Punakaiki, which proved very successful and the design was used for the new fences. The Trust talked to OPUS, NZTA and DOC about building a $40,000 penguin protection fence along 2.6km of coastal highway, stretching from just north of Meybille Bay through to Limestone Creek since 2009. On 22nd August 2014, the last gate in the new fence was officially closed by Buller Mayor, Garry Howard. A year later, and ahead of the 2015 breeding season, the Trust completed another 300m of fencing along the coast highway near Seal Island, another location where road kills have been recorded. These fences have cut road kills in the area from 6-8 birds annually to zero. We’re very grateful to the local teams from Fulton Hogan and WestReef, who, with annual support from the NZ Transport Agency, carry out weed spraying and maintenance. The former ensures that the vegetation does not become too abundant and heavy, which could damage the fence. The fence is a deceptively simple black geosynthetic mesh that will prevent penguins straying on to the road. Driveway and beach access has been retained, and the Trust has installed spring-loaded gates. A similar fence erected by the Friends of Lillico Penguins in Tasmania along a major highway, has been very successful in bringing down the numbers of penguins killed on the road and increasing the penguin population. June 2020 Update We published this news story confirming that many penguins have been prevented from being killed on the road by the penguin protection fence: https://www.westcoastpenguintrust.org.nz/news/over-60-penguins-saved-statistics-show-that-fence-is-protecting-penguins/ June 2023 Update With little penguins thriving on the sea side the West Coast Penguin Trust's penguin protection fence north of Punakaiki, penguins are starting to explore beyond the three colonies that were protected and finding their way past the ends of the fence through gaps. Sadly one penguin has been killed on the road and others have been rescued and returned to the sea side of the fence. We're therefore thrilled to report that one of those gaps in the fence has just been filled, protecting penguins at the northern end of the main fence line just in time for the new breeding season. Our thanks go to WestReef for getting the work done the minute they were able to including the traffic management and other safety measures, and to Waka Kotahi for both permission and support through an annual grant to help maintain the fence. We would also like to thank Geofabrics New Zealand for the very generous discount on the special fence mesh. Geofabrics (then Maccaferri) helped us out in the same way when we first installed the penguin protection fence back in 2014. The mesh has stood up to the coastal assaults of sun and salt brilliantly, just as expected.
How can you help?
The completed fence requires occasional maintenance and costs will be ongoing.
Your donation will help to keep the penguin protection fence working as designed and you can donate via our Donate page.
Also, if you're driving past the fence and notice any issues, perhaps a gate wedged open or some damage, please close the gate or let us know so that problems can be fixed immediately.
