Tiritiri Matangi Island boasts one of the most successful community-based conservation projects in the world. In just 10 years, thousands of volunteers have planted close to 300,000 trees, restoring pasture to native forest and creating a home for some of New Zealand's most endangered birds - including takahē, little spotted kiwi and kōkako.

School visits must be booked and you will have to plan well ahead because of the island's popularity.
