New Zealand. It reaches a height of close to the south coast. The island is home to
Sirocco, an internationally famous
kākāpō, a rare species of

History and names
The island is one of many geographic features in New Zealand to have a
dual place name, consisting of the English and
Māori names separated by a slash. The English name "Codfish Island" refers to the endemic
blue cod, which is fished commercially in surrounding waters by trapping in baited pots.
The Māori name "" means "new land", which dates back to the early days of
Pākehā settlement in New Zealand. Responding to concerns and allegations that local Māori women were being harassed by
sealers on nearby Rakiura, the local
Ngāi Tahu rangatira,
Honekai, designated Whenua Hou as the site of a new mixed race settlement where early Pākehā could live with their Māori wives under his protection. This encouraged sealers to move to Whenua Hou, alleviating the issues which their presence had caused on nearby Rakiura and making Whenua Hou one of the first permanent mixed Māori and European settlements in the region.
Wildlife

Kākāpō

The first
kākāpō were transferred to Codfish Island / Whenua Hou in 1987 from
Rakiura in order to provide a safe haven for the birds. Following the eradication of
possums and rats in 1998 and the transfer of
weka to other islands, the island became a predator-free bird sanctuary and the focus of kākāpō recovery efforts.
Codfish Island / Whenua Hou provides kakapo with a home similar to their original home of Rakiura. As it holds the majority of the breeding population of critically endangered kākāpō it has become the centre for kākāpō recovery. In 2002, 24 kākāpō chicks fledged on the island. In 2009 and 2016, 33 and 32 chicks fledged respectively.
Its most famous resident is
Sirocco, a kākāpō born in 1997; Sirocco became the government's "Official Spokesbird for Conservation" in 2010.
As of September 2021, 75 kākāpō reside on Codfish Island / Whenua Hou
