Translocation of kākāriki karaka
Watch the documentary
The story
The first translocation of kākāriki karaka (orange-fronted parakeet) to the Brook Waimārama Sanctuary took place on 18 and 20 November 2021; the birds were raised in captivity in Christchurch at The Isaac Conservation and Wildlife Trust. Subsequently, this was followed by additional translocations in 2022 of birds bred and raised at ISAACS and also Orana Park in Christchurch. The most recent translocation of kākāriki karaka was 24 January 2023 with a further 9 birds bred at Auckland Zoo added to the growing population of these important manu (birds) in the Sanctuary.
After a 100-year absence from the region a 2023 nationwide status report on the species prepared by the Department of Conservation has noted that the Sanctuary kākāriki population is “tracking well”. The Sanctuary survey found 170 birds; of note, only three banded birds were found during the survey. Most sightings were of unbanded birds during extensive searches in July, this resulted in a dramatic increase in the estimated size of the population. At a range of up to 214 birds, the population at the Sanctuary represents the largest group in the country. The latest population results are very positive and reinforce that the population has not just established, but is thriving, in the Sanctuary environment.
This achievement is regarded as very important to the Sanctuary Trust, staff, supporters and volunteers as it represents proof of concept.
What does this mean for us?
The reintroduction of kākāriki karaka (the orange fronted parakeet) follows the earlier release of tīeke (saddleback) into the Sanctuary in April 2021. Followed by the translocation of 44 powelliphanta (native carnivorous land snails) signal that the Department of Conservation, local iwi and others are confident that we have the necessary bio-security policies, procedures, infrastructure and technical expertise to ensure reintroduced species have the best possible chance of survival and to increase in numbers. This opens the way to further reintroductions, the Sanctuary vision is to return a number of species such as tuatara, kaka, kiwi, and others to the Sanctuary habitat.
What is a successful translocation?
Establishment is achieved when a population has become self-sustaining. Depending on the release environment and species involved, this may take several years and may require multiple follow-up translocations to ensure that the population is large enough, and has sufficient genetic diversity, for long-term stability.
There are many factors that contribute to a successful translocation, among them handling the birds with care, selecting healthy individuals, keeping the birds well fed and watered, and minimizing stress and overheating during transport and release.
Translocations of birds to the mainland is more challenging than to offshore islands. The water surrounding islands acts not only as a barrier for invasive predators, but also hinders endangered birds from leaving the safety of the islands. In contrast, due to the open nature of mainland sanctuaries, post-release dispersal away from the release site can be a challenge. The Brook Waimārama Sanctuary is unique because it is connected to the much larger Mount Richmond Forest of approximately 160,000 hectares; the possibility that the reintroduced kākāriki will disperse beyond Sanctuary and be at risk of predation is very real. It is hoped that because the Sanctuary will provide more than ample food and water that the manu (birds) will remain within the Sanctuary fence.
Once the birds are released, maintaining the biosecurity predator-free status of the Sanctuary will be essential. This includes maintaining the integrity of the fence, rapid and effective responses to breaches, ongoing monitoring to detect predator incursions and continuing regular Sanctuary-wide pest surveys. While this is already being done, there will have to be greater vigilance from now on.
The translocation process
In November the Brook Waimārama Sanctuary received 20 critically endangered kākāriki karaka (orange-fronted parakeet/OFP) that were raised at the Isaac Conservation Wildlife Trust (ICWT) in Christchurch. Until recently ICWT have been the sole captive breeding facility OFP’s. Since 2003, the Trust has bred over 600 birds and contributed significantly to the survival of this species. Multiple breeding pairs are held on site and all offspring produced are either released or retained for the captive breeding programme. In recent times, ICWT has begun to convert existing aviaries originally constructed for other species into OFP breeding aviaries. This work, alongside other captive breeding facilities joining the programme, will lead to a major increase in captive breeding capacity, resulting in more captive bred birds available for release into suitable locations.
The transfer to BWST is a significant event – it is the first time kākāriki karaka have been introduced to a sanctuary and represents a significant new site for the Kākāriki Karaka Recovery Programme.
The birds were to Nelson Airport by Air New Zealand and then helicoptered to the Sanctuary, where they were initially held in special on-site aviaries for a few days to acclimatise before their release into the wider sanctuary.
As well as the conservation significance, this transfer is culturally significant as kākāriki karaka are a taonga species and the birds are being transferred to outside of the Ngāi Tahu takiwa.
What you can do to help
The Sanctuary needs to continue to be predator-free which means high biosecurity vigilance, so we need lots of volunteer help with pest monitoring surveys, we also need donations and supporter fees to help cover our operational costs. Why not join us?
When visiting the Sanctuary it will help us if people report back to the Visitor Centre if they sight or hear kākāriki (and/or tīeke) during their walk. Birds will have different coloured leg bands and if these can be observed, without disturbing the bird, it will help us build a picture of where individual birds are within the Sanctuary. We would also welcome high-quality pictures and video footage to add to our archives.
People can help by observing the rule of not walking their dogs close to the outside of the fence of the Sanctuary.

Ngā mihi nui to Booster Wine Group and @wwfnz 🦎💚
Back in November 2024, generous support from Booster Wine Group ($9,447), WWF-New Zealand ($15,000) and other generous donors who helped make our tuatara translocation possible, returning these ancient reptiles to their ancestral home here in Whakatū Nelson - add with support and guidance from Ngati Koata who are the kaitiaki
Their funding supported key costs such as specialist animal care, transport, habitat preparation and ongoing monitoring for the 56 tuatara now living safely inside our predator-free enclosure at the Sanctuary.
We’re incredibly grateful for partners like Booster Wine Group and WWF-New Zealand, whose commitment to conservation creates a lasting legacy for tuatara and for everyone who visits the Sanctuary to learn about these remarkable taonga. 🌿

🌿 Ngahere Neighbourhood: koru of the mamaku (black tree fern)
Few sights in the ngahere are as iconic as the unfurling koru of a mamaku (Sphaeropteris medullaris). These towering tree ferns can reach up to 20 metres tall, with elegant black trunks patterned by hexagonal scars from fallen fronds.
Their massive fronds can stretch over five metres long, arching high above the forest floor to form a shady green canopy. The stalks and undersides are covered in small, spiny-edged scales — a key feature that helps distinguish mamaku from other large tree ferns.
Mamaku are widespread across Aotearoa, especially in lowland and coastal forests of the North Island and the wetter regions of the South. As new fronds uncurl, the koru shape symbolises new life, growth, and renewal — a form that continues to inspire art, design, and our connection to nature.

We are proud to acknowledge Ngati Toa Rangitira as kaitiaki of the kiwi pukupuku (little spotted kiwi) now settling into life in the Sanctuary.
Their guidance and mātauranga were central to this year’s translocation — from naming the birds to the ceremony at our visitor centre.
Kiwi pukupuku are a treasured taonga, and we’re grateful to work alongside Ngāti Toa Rangatira and our iwi partners in supporting their return to Whakatū.
Ngā mihi nui to everyone involved in bringing these kiwi home.

🌼 Ngahere Neighbourhood: mikoikoi (New Zealand iris)
With its elegant fans of golden-green leaves and delicate white blooms, mikoikoi (Libertia ixioides) brings quiet beauty to the ngahere. This hardy perennial herb is found from coastal cliffs to mountain slopes throughout Aotearoa and is a true New Zealand endemic.
In spring and early summer, mikoikoi produces clusters of white, three-petalled flowers that give way to striking orange seed capsules. Its leaves often take on yellow tones in full sun, forming dense clumps that help stabilise soil on ridges and banks.
Mikoikoi belongs to the iris family and is one of several Libertia species unique to Aotearoa. There are two species found within the Sanctuary, with Libertia moorae being endemic to Te Tau Ihu (Top of the South). You’ll often find it along the Sanctuary’s sunny forest edges and stream banks — a subtle but beautiful reminder of our native flora’s diversity and resilience.
🔎 Species: Libertia ixioides

✨ An unforgettable kiwi pukupuku encounter
Sometimes, you just get lucky.
Some of our night tour visitors got the surprise of a lifetime. While admiring the glow worms, the group suddenly heard a male kiwi pukupuku calling nearby. Moments later, one of our visitors felt something gently brushing against her feet.
When the torch came on, there it was — a kiwi pukupuku standing right beside the group.
Even better, someone captured the moment on video.
This curious kiwi wandered off into the ngahere… then strolled back for another look. Encounters like this are incredibly rare, and seeing kiwi confidently exploring the Sanctuary — only months after their arrival in May — is a wonderful sign of how well they’re settling and thriving.
A magical night none of us will forget.
