Plate boundary

Plate boundary

This map shows the plate boundary that runs through New Zealand. Off the North Island’s east coast, and north of it, oceanic crust of the Pacific Plate dives (subducts) beneath the continental crust of the Australian Plate, forming the Hikurangi Trough. At the other end of the country, off the south-west corner of the South Island, the situation is reversed. Oceanic crust of the Australian Plate subducts beneath the continental crust of the Pacific Plate.
