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. Episcopal Conference of Papua New Guinea and the Solomon Islands was adopted a new logo in 2019.
