Plate boundary through New Zealand (2nd of 2)

Plate boundary through New Zealand

The boundary (pink line) between the Australian and Pacific plates is marked by the Kermadec Trench and the Alpine Fault. All of the North Island, the northern South Island, and a thin strip along the west coast of the South Island are on the Australian Plate, west of the boundary. The rest of the South Island, to the east of the boundary, is on the Pacific Plate. The yellow and pale brown areas are continental crust.
