The Diocese of Polynesia, or the Tikanga Pasefika serves Anglicans in Fiji, Tonga, Samoa and the Cook Islands, within the Anglican Church in Aotearoa, New Zealand and Polynesia.

Polynesia is a diocese, and its Bishop is automatically accorded the style archbishop and the formal prefix Most Reverend.

Each of these three is metropolitan archbishop to his respective tikanga, and informally they also share the primacy, although in practice they are required to elect one of their number to be the formal Primate, and serve on the international Anglican Communion Primates' Meeting.

Anglicanism first came to Samoa around 1890; in 1897, Alfred Willis, Bishop of Honolulu, visited Apia to baptise eight and confirm eleven people; he retired to Tonga in 1902 and was licensed assistant bishop in Tonga by Twitchell in 1913.

[8] On Lady Day (25 March) 1994, Viliami Halaʻapiʻapi was consecrated Assistant Bishop of the diocese;[9] called Father Bill, he died in office in early 2003.
