The word pā (Māori pronunciation: [ˈpaː]; often spelled pa in English) can refer to any Māori village or defensive settlement, but often refers to hillforts – fortified settlements with palisades and defensive terraces – and also to fortified villages. Pā sites occur mainly in the North Island of New Zealand, north of Lake Taupō. Over 5,000 sites have been located, photographed and examined, although few have been subject to detailed analysis. No pā have been yet located from the early colonization period when early Polynesian-Māori colonizers lived in the lower South Island. Variations similar to pā occur throughout central Polynesia, in the islands of Fiji, Tonga and the Marquesas Islands.
In Māori culture, a great pā represented the mana (prestige or power) and strategic ability of an iwi (tribe or tribal confederacy), as personified by a rangatira (chieftain). Māori built pā in various defensible locations around the territory (rohe) of an iwi to protect fertile plantation-sites and food supplies.
