The Anglican Church in Aotearoa, New Zealand and Polynesia, formerly the Church of the Province of New Zealand, is a province of the Anglican Communion serving New Zealand, Fiji, Tonga, Samoa, and the Cook Islands. Since 1992 the church has consisted of three tikanga or cultural streams: Aotearoa, New Zealand, and Polynesia. The church's constitution says that, among other things, it is required to "maintain the right of every person to choose any particular cultural expression of the faith". As a result, the church's General Synod has agreed upon the development of the three-person primacy based on this three tikanga system; it has three primates, each representing a tikanga, who share authority.

The Anglican Communion is the third largest Christian communion after the Roman Catholic and Eastern Orthodox churches. Formally founded in 1867 in London, the communion has more than 85 million members within the Church of England and other autocephalous national and regional churches in full communion. The traditional origins of Anglican doctrine are summarised in the Thirty-nine Articles (1571). The archbishop of Canterbury in England acts as a focus of unity, recognised as primus inter pares, but does not exercise authority in Anglican provinces outside of the Church of England. Most, but not all, member churches of the communion are the historic national or regional Anglican churches.
