335: 175:. On the east coast of the North Island between the Pāhaoa and Māhia canyons there is not direct drainage from the coast into the trough as the seafloor has a number of intermediate ridges and basins. In terms of being a definite trench with two sides, this is found on the sea floor north of the Māhia Peninsula but is broken by the Tuaheni submarine landslide at about 38°50'S, and the submarine Ruatōria debris avalanche at about 38°S. Beyond the Ruatōria debris avalanche the 364:. The far south area of the trough near the Kaikōura Canyon, the Subtropical Front forms a convergence zone between the subtropical and subantarctic water masses represented by the Southland Current down to about 1,000 m (3,300 ft). This region of ocean has been determined to be one of the most productive marine ecosystems on the planet. At this end of the trench, many deep water species are found close to the shore.

could be associated with the subduction margin before it intercepts the geographical southernmost point of the Kermadec Trench as presently defined at 37° 45′ 16.27″ S by GEBCO. The Marine Gazetteer defines the southern limit of the Kermadec Trench much further north as 35°30' S. and there is different mapping in the historic geological literature.

full analysis is nuanced, with flows from ten turbide triggering catchments but also flows that may be due to submarine land sliding from shaking associated with ground-motion amplitude peaks that produce failure in muddy sediments. The catchment of the Cook Strait Canyon was a large contributor to the turbidite deposits from the earthquake.
135:), commences in the south and trends to the eastern side of the trough. By the latitude of Cook Strait the channel is about 80 m (260 ft) below the general level of the trough. The seafloor Hikurangi Channel continues along its eastern side, until at the Māhia Peninsula it breaks off towards the east through the 159:, where the sea floor drops to the depth of the trough. Extending from the hilly coast north of Kaikōura the undersea Kowhai canyons are to the west of the trough. Towards the north eastern part of Cook Strait is the Cook Strait Canyon with part of the trough being 2,250 m (7,380 ft) deep. Off 573:
The northern limits of the trough are ill-defined. Seismic geological studies are consistent with the trough being buried under the Ruatōria debris avalanche, and there is an unnamed feature on the northern side of the Ruatōria debris avalanche south of the Ruatōria Scarp.

Because of the delivery of waters by the Lower Circumpolar Deep Waters and current and coastal drainage and surface currents such as the East Cape Current a rich marine ecosystem exists in the coastal waters over the trench.
