Deep in Nelson Lakes National Park, the Rotoiti Nature Recovery Project stands as one of New Zealand’s pioneering mainland island conservation initiatives. Launched in 1997 and managed by the Department of Conservation, the project restores native ecosystems across 5,000 hectares of beech forest through intensive predator control. It protects species such as kea, kākā and great spotted kiwi while involving local communities in ongoing restoration work. Visitors can explore walking tracks in the area and learn about the recovery of native flora and fauna.

About the Rotoiti Nature Recovery Project
The Rotoiti Nature Recovery Project began in 1997 as one of six original DOC mainland island projects. It uses natural boundaries and intensive pest management to restore a representative section of alpine honeydew beech forest on the slopes of the St Arnaud Range.
The project area expanded from an initial 825 hectares to its current 5,000 hectares, encompassing forest from the shores of Lake Rotoiti at 630 metres up to alpine peaks at 1,700 metres. Red, silver and mountain beech forests dominate the landscape and support a range of native birds and plants.
Intensive trapping and baiting target stoats, rats, possums and feral cats. These efforts have allowed populations of kākā, kea and other species to recover and enabled the reintroduction of great spotted kiwi.
The project also protects plants such as mistletoe and invertebrates including Powelliphanta snails. Long-term monitoring tracks pest numbers and native species responses to guide ongoing management.
Visiting the Project Area
St Arnaud serves as the main gateway to the project area and Nelson Lakes National Park. The village offers a visitor centre, accommodation and basic services.
Short walks and longer tracks start from Kerr Bay and other points around Lake Rotoiti. Visitors can observe the forest ecosystem while following Leave No Trace principles and staying on marked paths.
The area lies within a national park, so standard DOC regulations apply. Dogs are not permitted in most parts of the park, and visitors should check current conditions at the Nelson Lakes Visitor Centre.
Community Involvement and Partnerships
Friends of Rotoiti, a volunteer group formed in 2001, supports predator control, monitoring and education programmes. Local schools and residents participate in trap-building and other activities.
The project works in partnership with Ngāti Apa ki te Rā Tō and other groups. These collaborations integrate community knowledge and resources into conservation planning.
What Visitors Often Say
