Subduction beneath the North Island

Subduction beneath the North Island

This east–west cross-section through the central part of the North Island illustrates how the Pacific Plate descends (subducts) beneath the Australian Plate. The Australian Plate acts rather like a bulldozer’s blade, and the sediments on top of the Pacific Plate are scraped off and crumpled, forming the hills of the Wairarapa and Hawke’s Bay.
