Stoats in New Zealand
Stoats (''Mustela erminea'') were introduced into New Zealand to control rabbits and hares, but are now a major threat to the native bird population. The natural range of the stoat is limited to parts of the Northern Hemisphere. Immediately prior to human settlement, New Zealand did not have any land-based mammals apart from bats, but Polynesian and European settlers introduced a wide variety of animals.
==Introductions of stoats==
The rabbit was introduced as a food and game animal by European settlers and by the 1870s, it was becoming a serious threat to the newly developed farming economy. Farmers began demanding the introduction of mustelids (including stoats) to control the rabbit plague. Warnings about the dangers to bird life from stoats were given by scientists in New Zealand and Britain, including the New Zealand ornithologist Walter Buller. The warnings were ignored and stoats began to be introduced from Britain in the 1880s, then, within six years, drastic declines in bird populations were noticed.
In December 2010, a stoat was seen on what was thought to be the stoat-free Kapiti Island, and by August the next year DOC had managed to kill three. It is thought that they could not have swum the five kilometre stretch of open sea from the Kapiti Coast.
