On the Lake Moeraki coastline in South Westland NZ winter is approaching in June. For most wildlife winter is a time they hunker down and are not active as the keep warm and await the arrival of spring.
For Tawaki/Fiordland Crested Penguins winter is when they arrive in July from 6 months feeding and sleeping on the Southern Ocean to start their 2026 breeding season.
We will be guiding half-day Tawaki penguin viewing trips from October 2026.
To recognise just how special are Tawaki Penguins we are re-posting our most popular story from 2025-2026, a little video Gerry took of three Tawaki heading into the Tasman Sea to get food for their fast growing chicks.
We have also put below a backgrounder on the previous 2024 season's Tawaki breeding success along the South Westland coastline.
This survey shows approximately 85% breeding success for the 2024 season.
Wilderness Lodge Lake Moeraki Guided Tawaki Penguin viewing trips for Lodge guests start on 1 October 2026

Tawaki are the third rarest of the world's 18 penguin species and nest only in the south-west corner of New Zealand.
Over the last 36 years from Wilderness Lodge Lake Moeraki we have monitored several Tawaki Penguin colonies and been actively involved in their protection. These Lake Moeraki coastline colonies have shown a steady increase in numbers of breeding penguins over this long period. A significant contributor to that breeding success is protection of the coastal forest breeding areas, prevention of disturbance by people and active control of introduced predators including stoats, rats, possums and domestic dogs.
In addition to looking after our Lake Moeraki coastline monitored colonies, the Wilderness Lodge and our guests have financially helped the West Coast Penguin Trust each year with a major funding contribution to their schools and community education and penguin protection and monitoring work.
The West Coast Penguin Trust Annual Report has just come out and reports on breeding success at 3 main Tawaki Penguin breeding areas in South Westland; the Lake Moeraki coastline, Jackson Head and Gorge River.
Approximately 85% breeding success at the most vulnerable egg to fledged chick stage is great news for these wild birds. Tawaki's breeding success is an encouraging contrast to the sad plight of Hoiho, the other endemic large penguin nesting of the NZ mainland found in the SE corner of the South Island. This Hoiho population has declined 83% since 1996 to just 163 breeding pairs by 2023. Conservationists fear it could become extinct by 2060.

Fiordland crested penguins / tawaki
• After a very successful season in 2023, with several monitored nests raising two chicks, rare for crested penguins, the 2024 season was back to a more normal level of breeding success.
• Tawaki Ranger, Sarah Kivi, monitored nests at two sites in South Westland twice during the season. The first checks were in early September, looking for nests with eggs and then later in the month to check for chicks.
• At the colony north of Haast, 10 active nests were found, of which two failed at egg stage and eight had ten chicks at the second visit. A third visit from Lucy found the same chicks alive but it’s not clear or perhaps even likely that both chicks survived in the two nests where they were seen, so 8 chicks fledged from 10 breeding attempts is assumed, at least as a minimum.
• At the Jackson Head colony, 11 nests were monitored, 20 eggs were seen, 1 nest failed at egg stage and another at chick stage. Nine nests successfully hatched 11 live chicks at the second visit, but again, we assume a minimum of 9 chicks fledged from 11 breeding attempts.
• Sarah reported a large slip along part of the west-facing Jackson Head colony that would have destroyed several nesting sites unfortunately.
• Tawaki Ranger, Catherine Stewart, continued the more frequent monitoring of nests at Gorge River, for the 11th year, the earlier years started by daughter and Trustee, Robin Long.
• Monitoring comprised six checks of 27 nests between mid-August and late October, nine of which had trail cameras deployed. A further 15 nests used in previous years were checked but were not used this season. Poor weather meant access around the colony was difficult. Of the 27 nests with penguins, 24 had penguins sitting on eggs by 20th August. All eggs were hatched by 22nd September.
• Two of the nests monitored by trail camera appeared to have failed by mid-September; trail camera footage for one showed the nest failure after a stoat visit. Two healthy chicks were present close to the end of the chick guard stage, after which chicks move around and ‘crèche’, hanging out together waiting for parents to return with food. It is therefore difficult to determine chick survival rate, but we could estimate that 9 chicks fledged from the nest with cameras, a similar rate to the other South Westland
sites, resulting in an average of 84% breeding success, where 100% would be one chick per nest.
