South East Island
|Native name: Rangatira|
|Area||2.18 km2 (0.84 sq mi)|
South East Island (Rangatira in Maori) is the third largest island in the Chatham Islands archipelago, and covers an area of 218 hectares (539 acres). It lies 800 kilometres (497 mi) east of New Zealand's South Island off the south-east coast of Pitt Island, 55 kilometres (34 mi) south-east of the main settlement, Waitangi, on Chatham Island.
According to oral traditions, ancient Moriori used to travel to Rangatira by waka korari to capture titi muttonbirds. However, there is no material evidence of those expeditions, such as dendroglyphs (tree carvings) or petroglyphs (rock art).
European farmers ran sheep, goats and cattle on Rangatira until the 1960s when the last of these were removed. Today the island is a gazetted nature reserve, thus access to the island is restricted and controlled by the Department of Conservation.
Flora and fauna
Rangatira is host to several rare and endemic species of birds and plants and is a sanctuary for endangered invertebrates such as the giant stick insect, Rangatira spider, coxella weevil and the Pitt Island longhorn beetle. It is most famous for being the habitat for the endangered black robin, rescued from near extinction by a dedicated team led by Don Merton, who used foster parent birds to raise the chicks of black robin. The island has been identified as an Important Bird Area by BirdLife International because it supports large breeding colonies of broad-billed prions (330,000 pairs), Chatham petrels (up to 1000 pairs) and white-faced storm petrels (840,000 pairs). Rangatira was the stronghold, and last remaining breeding site for the Chatham petrel until recently; new colonies on Pitt and Chatham Islands are being established.
