The Manawatāwhi / Three Kings Islands are a group of 13 uninhabited islands about 55 kilometres (34 mi) northwest of Cape Reinga / Te Rerenga Wairua, New Zealand, where the South Pacific Ocean and Tasman Sea converge. They measure 6.85 km2 (2.64 sq mi) in area. The islands are on a submarine plateau, the Three Kings Bank, and are separated from the New Zealand mainland by an 8 km wide, 200 to 300 m deep submarine trough. Therefore, despite relative proximity to the mainland, the islands are listed with the New Zealand Outlying Islands. The islands are an immediate part of New Zealand, but not part of any region or district, but instead Area Outside Territorial Authority, like all the other outlying islands except the Solander Islands.

Its southern portion contains the Manawatāwhi / Three Kings Islands which have biological significance as they are host to unique species and important marine ecosystems.
