Question - New Zealand lies on the boundary of what two tectonic plates?

New Zealand lies on the boundary of what two tectonic plates? 

Answer: Australian and Pacific.

This position on the edge of two tectonic plates gives New Zealand areas of mountain building, earthquakes and volcanic/geothermal activity. These two plates are moving about 40mm per year relative to each other. There is a subduction zone where the Pacific plate slides under the Australian plate to the east of NZ north of Cook Strait (the centre of NZ) which causes a lot of volcanic activity in the North Island. Through most of the South Island the plates slide past each other along the Alpine Fault (strike-slip zone).
