Archaeological demonstrate suggests that New Zealand was populated by fishing and hunting people of East Polynesian ancestry perhaps 1,000 years before Europeans arrived. Known to some scholars as the Moa-hunters, they may have merged with later waves of Polynesians who, according to Maori tradition, arrived between 952 and 1150. Some of the Maoris called their new homeland "Aotearoa," usually translated as "land of the long white cloud."

The Maori gradually recovered from population decline and, through interaction and intermarriage with settlers and missionaries, adopted much of European culture. In recent decades, Maori have become increasingly urbanized and have become more politically active and culturally assertive. New Zealand was declared a dominion by a royal proclamation in 1907. It achieved full internal and external autonomy by the Statute of Westminster Adoption Act in 1947, although this merely formalized a situation that had existed for many years.
