Which Oceanian capital is located on the island of Tongatapu?

Nukuʻalofa is the Oceanian capital located on the island of Tongatapu.

Nukuʻalofa is Tonga’s capital and largest city, situated on Tongatapu’s north coast. Tongatapu is the country’s main and most populous island, in Tonga’s southern island group. The city is Tonga’s political and administrative center, containing the national government, Royal Palace, and Parliament.

The settlement’s deep-water harbor helped make it an important site for trade and transport. Tonga’s 1875 constitution formally established Nukuʻalofa as the capital. The name is often written without the ʻokina as “Nukualofa,” but both forms refer to the same city; the quiz’s spelling is the more precise modern form.

The other options are capitals of different Pacific nations: Port Vila is in Vanuatu, Honiara is in Solomon Islands, and Apia is in Samoa. None is located on Tongatapu.
