At the Ōtorohanga Kiwi House, conservation is at the heart of everything we do, and we are thrilled to share a significant milestone in our efforts to protect New Zealand’s unique wildlife. In collaboration with the Department of Conservation (DOC) and local iwi, we recently released 60 Mahoenui giant wētā onto an offshore predator-free island, helping to sustain and strengthen an existing population in this protected habitat.
A Species Worth Protecting
The Mahoenui giant wētā (Deinacrida mahoenui) is one of New Zealand’s most extraordinary insects, a true living fossil. Once widespread, habitat destruction and the introduction of predators like rats and stoats have drastically reduced their numbers, leaving them clinging to survival in a few scattered locations. Thanks to dedicated conservation efforts, these wētā have been bred in managed care and carefully reintroduced into safe environments where they can thrive.
A Collaborative Effort
This release was made possible through the strong partnership between the Ōtorohanga Kiwi House, the Department of Conservation, and local iwi. Each partner played a crucial role in ensuring the success of this conservation initiative, from the careful breeding and monitoring of the wētā to selecting the ideal island site where they would have the best chance of survival.
For iwi, this project represents not only a step towards restoring biodiversity but also an important act of kaitiakitanga (guardianship) over the land and its native species. Their involvement ensures that cultural values and environmental stewardship go hand in hand in our conservation work.
A Safe New Home
The predator-free island provides the ideal environment for the Mahoenui giant wētā to re-establish and grow in number without the constant threat of introduced predators. Here, they will play their natural role in the ecosystem, helping to maintain balance and biodiversity. Ongoing monitoring will track their progress, ensuring they adapt well to their new home.
Why It Matters
Every conservation success story, big or small, brings us closer to preserving New Zealand’s precious wildlife for future generations. The release of these wētā is not just about one species—it’s about restoring ecosystems, maintaining balance in nature, and fulfilling our responsibility as caretakers of Aotearoa’s unique biodiversity.
We are incredibly proud to be part of this initiative and grateful to all those who contributed to making it happen. Conservation is a collective effort, and with the support of our community, we can continue to protect and restore the incredible species that call New Zealand home.
