The Chatham Islands are an archipelago in the Pacific Ocean about 800 km east of New Zealand's South Island. They are administered as part of New Zealand. The archipelago consists of about 10 islands within an approximate 60 km radius, the largest of which are Chatham Island and Pitt Island. They include New Zealand's easternmost point, the Forty-Fours. Some of the islands, formerly cleared for farming, are now preserved as nature reserves to conserve some of the unique flora and fauna.
The islands were uninhabited when the Moriori people arrived around 1500 CE and developed a peaceful way of life. In 1835 members of the Ngāti Mutunga and Ngāti Tama Māori iwi from the North Island of New Zealand invaded the islands and nearly exterminated the Moriori, enslaving the survivors.
