Named forMount Hikurangi, in Māori mythology the first part of the North Island to emerge from the ocean

One of the major divisions of Zealandia, the Hikurangi Plateau (top right) drifted south and collided with parts of the mostly submerged continent.

The Hikurangi Plateau is an oceanic plateau in the South Pacific Ocean east of the North Island of New Zealand. It is part of a large igneous province (LIP) together with Manihiki and Ontong Java, now located 3,000 km (1,900 mi) and 3,500 km (2,200 mi) north of Hikurangi respectively.[2] Mount Hikurangi, in Māori mythology the first part of the North Island to emerge from the ocean, gave its name to the plateau.
