population of around 50, who are entirely mixed-race Anglo Euronesians. They are descended from an initial group of Anglo and Polynesian settlers in the 18th century. Pitcairn was later annexed by Britain, while Norfolk Island became an external territory of Australia, who are over 1,500 kilometers removed. Norfolk's present population is mostly European Australian, some are also Euronesians; these individuals are descended from Pitcairn Islanders that were relocated to Norfolk in 1852 because of overpopulation. The Micronesia adjacent islands became unincorporated territories of the United States, and they all have no permanent residents. The United States government restrict access to outsiders on some islands. Decolonization Oceania is generally considered the least decolonized region in the world. In his 1993 book France and the South Pacific since 1940, Robert Aldrich commented: Demographics In New Zealand, Māori constitute a significant minority, accounting for 16% of the total population according to the 2018 census. A considerable number of those who define themselves as Māori are also of European, and to a lesser but growing extent, of Asian descent. The indigenous peoples of Australia are the Indigenous Australians, who account for 2.5% of the total population according to 2011 census figures. The term 'Indigenous Australians' refers to both the Aboriginal peoples of mainland Australia and Torres Strait Islander peoples. Of the total 'Indigenous Australian' population, 90% identified as Aboriginal only, 6% identified as Torres Strait Islander and the remaining 4% identified as being of both Aboriginal and Torres Strait Islander origin. Papua New Guinea (PNG) has a majority population of indigenous societies, with some 700+ different tribal groups recognised out of a total population of just over 5 million. The PNG Constitution and other Acts identify traditional or custom-based practices and land tenure, and explicitly sets out to promote the viability of these traditional societies within the modern state. However, several conflicts and disputes concerning land use and resource rights continue between indigenous groups, the government and corporate entities. Migration between countries and territories in Oceania Hawaii boasts a large Micronesian population (including Guamese Chamorros), with many Micronesians having experienced discrimination at the hands of the native Polynesian Hawaiians. Migrants from areas such as the Federated States of Micronesia have also faced discrimination in Guam itself, despite both being ethnoculturally Micronesian. New Zealand has the largest population of Polynesians in the world; it consists not only of their native Māori population, but also of
