Māori are the indigenous Polynesian people of mainland New Zealand. Māori originated with settlers from East Polynesia, who arrived in New Zealand in several waves of canoe voyages between roughly 1320 and 1350. Over several centuries in isolation, these settlers developed their own distinctive culture, whose language, mythology, crafts, and performing arts evolved independently from those of other eastern Polynesian cultures. Some early Māori moved to the Chatham Islands, where their descendants became New Zealand's other indigenous Polynesian ethnic group, the Moriori.

Māori culture is the customs, cultural practices, and beliefs of the indigenous Māori people of New Zealand. It originated from, and is still part of, Eastern Polynesian culture. Māori culture forms a distinctive part of New Zealand culture and, due to a large diaspora and the incorporation of Māori motifs into popular culture, it is found throughout the world. Within Māoridom, and to a lesser extent throughout New Zealand as a whole, the word Māoritanga is often used as an approximate synonym for Māori culture, the Māori-language suffix -tanga being roughly equivalent to the qualitative noun-ending -ness in English. Māoritanga has also been translated as "[a] Māori way of life." The term kaupapa, meaning the guiding beliefs and principles which act as a base or foundation for behaviour, is also widely used to refer to Māori cultural values.
