The Hikurangi Plateau is an underwater plateau located off the northeastern coast of New Zealand's North Island. It is part of the larger Hikurangi Margin, which is significant for its geological features and tectonic activity. The plateau is known for its rich biodiversity and is an important area for marine research. This region is also associated with the subduction of the Pacific Plate beneath the Australian Plate, leading to various geological phenomena. The Hikurangi Plateau plays a crucial role in understanding plate tectonics and the dynamics of the Earth's crust in this part of the world.
