The largest Christian denomination is the Methodist Church of Fiji and Rotuma. With 34.6% of the population (including almost two-thirds of ethnic Fijians), the proportion of the population adhering to Methodism is higher in Fiji than in any other nation. Roman Catholics in Fiji are headed by the Metropolitan Archdiocese of Suva, whose province also includes the dioceses of Rarotonga (on the Cook Islands, for those and Niue, both New Zealand-associated countries) and Tarawa and Nauru (with see at Tarawa on Kiribati, also for Nauru) and the Mission Sui Iuris of Tokelau (New Zealand).
