Whānau

Whānau is a Māori-language word for extended family, now increasingly entering New Zealand English, particularly in official publications.

In Māori society, the whānau is also a political unit, below the level of hapū and iwi, and the word itself has other meanings: as a verb meaning to be born or give birth.
