Māori culture (Māori: Māoritanga) is the customs, cultural practices, and beliefs of the Māori people of New Zealand. A 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, is found throughout the world.
