The Diocese of Auckland is one of the thirteen dioceses and hui amorangi of the Anglican Church in Aotearoa, New Zealand and Polynesia. The Diocese covers the area stretching from North Cape down to the Waikato River, across the Hauraki Plains and including the Coromandel Peninsula.

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.
