Translocation of powelliphanta
Watch the documentary
The story
In June of 2022 thirty-five “nationally critical” endangered powelliphanta (native carnivorous) land snails were translocated to the Sanctuary, followed by an additional nine snails in September of 2022. The first snails were gathered in the Maitai Vallery and the Roding Water Reserve between 12-26 May 2022, and released in the Sanctuary on 17 June 2022. A second collection in the Rocks Hut/Coppermine Saddle area occurred 5-7 September, and nine additional powelliphanta were translocated/released in the Sanctuary on 8 September 2022. The short (approx. 7 minute) video documents the process of translocating these fascinating and rarely seen native snails.
Our thanks for external expert powelliphanta advice from Ian Millar, and Dr. Kath Walker of the Department of Conservation.
Our thanks also to Fraser Heal for the video production, and to all the staff and volunteers involved in collecting and translocating these precious taonga to the safety of the Sanctuary.
What does this mean for us?
The translocation of powelliphanta follows earlier translocations of kākāriki karaka (the orange fronted parakeet) and tīeke (saddleback) into the Sanctuary in April 2021.
The translocation of 44 powelliphanta signals 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, this is particularly the case with a species such as powelliphanta which are slow to reproduce.
The translocation process
In total, we located and translocated 44 snails in 2022 to the Sanctuary, these were located in the Rocks Hut/Coppermine Saddle vicinity, in the Roding Water Reserve and from Ngati Koata land forestry land in the Maitai Valley; the Sanctuary has permission from the Department of Conservation to locate an additional six powelliphanta at some point in the future.
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 powelliphanta during their walk and where you saw them. If you do sight powelliphanta, please do not disturb them, do not pick them up.

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.
🔎 Species: Sphaeropteris medullaris
🟢 Conservation status: Not Threatened

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.
🎟️ Want to experience the ngahere after dark? Join one of our guided night tours.
