Most Common Surnames in Chatham Islands ()

The Chatham Islands are an archipelago in the Pacific Ocean about 800 kilometres east of New Zealand's South Island. They are administered as part of New Zealand. The archipelago consists of about ten islands within an approximate 60-kilometre (30 nmi) radius, the largest of which are Chatham Island and Pitt Island (Rangiauria). 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.
