[2][3] These grounds usually include a wharenui (meeting house) and are usually affiliated with iwi (tribes) and hapū (sub-tribes).
[4] In Māori society, the marae is a place where the culture can be celebrated, where the Māori language can be spoken, where intertribal obligations can be met, where customs can be explored and debated, where family occasions such as birthdays can be held, and where important ceremonies, such as welcoming visitors or farewelling the dead (tangihanga), can be performed.
Like the related institutions of old Polynesia, the marae is a wāhi tapu, a 'sacred place' which carries great cultural meaning.
Generally the term marae is used to refer to the whole complex, including the buildings and the ātea.
The wharenui is the locale for important meetings, sleepovers, and craft and other cultural activities.
