Belief and religion

Traditional Māori beliefs have their origins in Polynesian culture. Concepts such as tapu (sacred), noa (non-sacred), mana (authority/prestige) and wairua (spirit) governed everyday Māori living, and there are also many Māori deities. Today, some Māori follow a variety of Christian faiths such as Presbyterianism, The Church of Jesus Christ of Latter-day Saints, Māori Christian groups such as Rātana and Ringatū, and also Catholic, Anglican and Methodist denominations. At the 2018 New Zealand census, 7.7 per cent of Māori were affiliated with Māori religions, beliefs, and philosophies; 29.9 per cent with Christian denominations and 53.5 per cent of Māori claimed no religion. Proportions of Christian and irreligious Māori are comparable with European New Zealanders.

Many Māori people observe spiritual traditions such as tapu and noa. Certain objects, areas, or buildings are tapu (spiritually restricted), and must be made noa (unrestricted) by ceremonial action. It is common practice, for instance, to remove one's shoes before entering a wharenui (meeting-house), a token of respect for the ancestors who are represented and spiritually present within the wharenui. Another spiritual ritual is hurihanga takapau (purification), practised when fishing to ensure there is no tapu on the fish.
