A community-led approach to restoration.
Our Story
The Ōhiwa Headland Sanctuary Trust was founded in August 2016 with the vision of restoring the natural character of the Ōhiwa Headland to create a Sanctuary for native fauna and flora to flourish. This is a community-led initiative that is inspiring the locals to actively manage animal and plant pests within the Headland, as well as increase native habitat through plantings. Through our collaborative efforts we aim to enhance the current flora and fauna and re-establish various threatened species through natural succession or potential reintroductions.
Located within the Ōpōtiki Ecological District, the Ōhiwa Headland is a coastal area rich in natural history and character that has significant biodiversity values not found at other sites within the Bay of Plenty. This prominent landscape which was once considered a defendable headland by early Māori was the foundation behind creating a defendable sanctuary for New Zealand’s native flora and fauna from introduced threats. The natural boundary of the Headland which consists of the Ōhiwa Harbour, Waiōtahe estuary and Pacific sea provides for a landscape where the removal and maintenance of predators to low levels is entirely feasible.
Our Community
The Trust is committed to a genuinely community‑led approach, recognising that the project’s success relies on the collective support of local residents, landowners, iwi, schools, and other key stakeholders who form its foundation.
Our community has shown strong and sustained commitment to predator control on the Ōhiwa Headland. Four local caregroups actively carry out on‑the‑ground biodiversity protection work and are supporters of our project. In return, the Ōhiwa Headland Sanctuary Trust has unified these efforts, enabling a coordinated, landscape‑scale predator control network.
Support from landowners is exceptionally high, with 98% of the 165 landowners in the operational area granting full access for pest control activities and reporting noticeable ecological improvements. Many households participate directly through backyard trapping and monthly catch reporting. In addition, 40 regular volunteers contribute to pest control and wider restoration work, reflecting a deeply engaged and environmentally motivated community.
