マオリ族に関するウィキの記述で意味が取れません
Naming and self-naming
Early visitors from Europe to New Zealand generally referred to the inhabitants as "New Zealanders" or as "natives", but Māori became the term used by Māori to describe themselves in a pan-tribal sense.
Māori people often use the term tangata whenua (literally, "people of the land") to describe themselves in a way that emphasises their relationship with a particular area of land – a tribe may be the tangata whenua in one area, but not in another. The term can also refer to Māori as a whole in relation to New Zealand (Aotearoa) as a whole.
The Maori Purposes Act of 1947 required the use of the term "Māori" rather than "Native" in official usage, and the Department of Native Affairs became the Department of Māori Affairs. It is now Te Puni Kōkiri, or the Ministry for Māori Development.
Before 1974, ancestry determined the legal definition of "a Māori person". For example, bloodlines determined whether a person should enrol on the general electoral roll or the separate Māori roll. In 1947, the authorities determined that one man, five-eighths Māori, had improperly voted in the general parliamentary electorate of Raglan. The Māori Affairs Amendment Act 1974 changed the definition to one of cultural self-identification. In matters involving money (for example scholarships or Waitangi Tribunal settlements), authorities generally require some demonstration of ancestry or cultural connection, but no minimum "blood" requirement exists.
