Question: What continent is the country encompassing Luahoko located?

full_context: Document 1: Oceania: Biogeographically, as a synonym for the Australasian ecozone and the Pacific ecozone (Melanesia, Polynesia, and Micronesia), with New Zealand forming the south - western corner of the Polynesian Triangle. To note, New Zealand may also be considered part of Australasia, despite being traditionally part of Polynesia. As an ecozone, Oceania includes all of Micronesia, Fiji, and all of Polynesia except New Zealand. New Zealand, along with New Guinea and nearby islands, part of the Philippine islands, Australia, the Solomon Islands, Vanuatu, and New Caledonia, constitute the separate Australasian ecozone. In the geopolitical conception used by the United Nations, International Olympic Committee, and many atlases, Oceania includes Australia and the nations of the Pacific from Papua New Guinea east, but not Indonesian New Guinea.
