Destiny Church is a far-right New Zealand Christian fundamentalist organisation variously described as a church, a religious movement, or a cult. Based in South Auckland and with a strong Māori conservative character, Destiny Church's direction and ideology is highly personalised around its leader and founder, Brian Tamaki, whose title is "Apostle Bishop", and his wife Hannah Tamaki. The couple founded Destiny Church in 1998, and quick growth led to it peaking in 2003 with approximately 5,000 members. As of the 2018 New Zealand Census, the organisation has a recorded 1,772 followers, under a third of the 6,000 claimed by Tamaki.
