List of Catholic dioceses in Papua New Guinea & Solomon Islands
The Catholic Church in Papua New Guinea and the Solomon Islands comprises only a Latin hierarchy;
neither country has a national episcopal conference, but they jointly form the Episcopal Conference of Papua New Guinea and the Solomon Islands, comprising five ecclesiastical provinces, each headed by a Metropolitan Archbishop, and a total of seventeen suffragan bishoprics.
There are no pre-diocesan, Eastern Catholic or other exempt jurisdictions.
All defunct (often pre-diocesan missionary) jurisdictions are direct precursors of current sees.
There is also an Apostolic Nunciature as papal diplomatic representation (embassy-level) to Papua New Guinea (at the national capital Port Moresby), in which the Apostolic Nunciature to the Solomon Islands is also vested.
