The Rātana Church (Māori: Te Haahi Rātana) is a Christian denomination of New Zealand Māori people based on the teachings and principles of the faith healer and prophet Tahupōtiki Wiremu Rātana. On 8 November 1918, Rātana received a divine revelation from the Holy Spirit which commanded him to unite the Māori people in worship of the One True God, Jehovah. On 5 July 1925, the Rātana Established Church of New Zealand was formally established and registered with the Registrar-General of New Zealand.
