Although shallower than the trenches north of it, the Hikurangi Trench reaches depths of 3,000 metres as close as 80 kilometres from shore. Its maximum depth is about 3,750 metres (12,300 ft).
At the southern end of the trench, off the coast of Marlborough, New Zealand, the seabed rises sharply, and because of the prevailing winds and tides in this area, many deep water species are found close to the shore. This food source attracts the whales for which the town of Kaikoura is famous.
The plate boundary continues inland along the Hope Fault. Here the plates converge much more obliquely, exhibiting transpression instead of subduction.
