In New Zealand, the Marlborough strike-slip faults link the Hikurangi subduction zone to the Alpine fault collision zone. Stratigraphic and structural analysis in the Marlborough region constrain the inception of the current strike-slip tectonics. Six major Neogene basins are investigated. Their infill is composed of marine and freshwater...

In eastern North Island New Zealand, oblique subduction of the Pacific Plate beneath the Australian Plate is associated with strain partitioning. Dextral along-strike component of displacement occurred first at Early Miocene major faults within the eastern fore-arc domain. These faults were active from Early Miocene to Pliocene times. Since...

EM12 swath-mapping and geophysical data collected during GEODYNZ-SUD cruise leg 1 along the Kermadec-Hikurangi margin reveal the structures associated with the transition from oblique intraoceanic subduction to very oblique sub-continental subduction and intra-continental transpression. Partitioning between strike-slip and compressional...

The southern Kermadec-Hikurangi convergent margin, east of New Zealand, accommodates the oblique subduction of the oceanic Hikurangi Plateau at rates of 4-5 cm/yr. Swath bathymetry and sidescan data, together with seismic reflection and geopotential data obtained during the GEODYNZ-SUD cruise, showed major changes in tectonic style along the...
