Pacific and Australian Plates

To the south of New Zealand, and underneath Fiordland, the two plates are also moving toward each other but here the Australian Plate is being subducted under the Pacific Plate.

Kermadec Trench

This subduction also results in the Taupo Volcanic Zone + shallow trenches such as the Hikurangi trough

The deepest trench in NZ is the 6,000-metre deep Puysegur Trench. Oceanic crust of the Australian Plate dives beneath the Pacific Plate. It is a mirror image of the Kermadec Trench to the north-east.

Continental crust colliding with continental crust. Both are light so neither subduct. Mountain ranges such as the Southern Alps are thrust up instead.
