Little Barrier Island

Little Barrier Island, or Hauturu in Māori (the official Māori title is Te Hauturu-o-Toi), lies off the northeastern coast of New Zealand's North Island. Located 80 kilometres (50 mi) to the north of Auckland, the island is separated from the mainland to the west by the Jellicoe Channel, and from the larger Great Barrier Island to the east by the Cradock Channel. The two aptly named islands shelter the Hauraki Gulf from many of the storms of the Pacific Ocean.

Settled by the Māori between 1350 and 1650, the island was occupied by them until the New Zealand government declared the island a wildlife sanctuary in 1897. Since the island came under control of the government, it has been under limited access, with only a few rangers living on the island. The Māori name of the island means "the resting place of lingering breezes". Along with its larger neighbour Great Barrier, it was given its English name by Captain James Cook in 1769.

The island is a nature sanctuary which has been described by the MBIE as "the most intact [native] ecosystem in New Zealand". However, several invasive species were introduced by both Maori and European settlers, including cats, which were destructive to local small bird and reptile species until they were eradicated between July 1977 and June 1980 in what was possibly New Zealand's costliest pest control programme. This was followed by a rat eradication programme from 2004. A cost benefit analysis has been published.^{: 558–567}
