Tiritiri Matangi Island is located in the Hauraki Gulf of New Zealand, east of the Whangaparaoa Peninsula in the North Island and north east of Auckland. The island is an open nature reserve managed by the Supporters of Tiritiri Matangi Incorporated, under the supervision of the Department of Conservation and is noted for its bird life, including takahē, North Island kōkako and kiwi. It attracts between 30,000 and 32,000 visitors a year, the latter figure being the maximum allowed by the Auckland Conservation Management Strategy.
