Codfish island or Whenua Hou is a small island (14 km²) located to the west of Stewart Island/Rakiura in southern New Zealand. It reaches a height of 249 m close to the south coast. It is a predator-free bird sanctuary and the focus of kakapo recovery efforts. The majority of the breeding population of critically endangered kakapo are currently located on this island. The island is also home to southern short-tailed bats, kākā, fernbirds, red and yellow-crowned parakeets, and a recently introduced population of yellowheads (mohua). Yellow-eyed and Fiordland penguins breed along the coastline.
The island is frequented by scientific researchers and Department of Conservation field workers along with public volunteers. The sole hut is located at Sealer's Bay in the northeast, with access by light aircraft or helicopter. The island is closed to visitors and unauthorised landing is prohibited.
The english name refers to the endemic blue cod or rawaru / pakirikiri, which is fished commercially in surrounding waters by trapping in baited pots. Whenua Hou means "new land" in Maori[1].
Tiny Codfish Island is home to about half the world's remaining kakapo
