  abstract = {{T}he convergent {S}outhern {K}ermadec margin is examined to study the structural development and mechanical parameters of the inner trench slope in response to the oblique subduction of the oceanic {H}ikurangi {P}lateau. {S}wath bathymetric data have been combined with other geophysical data to reveal that the {S}outh {K}ermadec inner trench wall is segmented into distinct upper, middle, and lower margins. {T}he lower margin is a nongrowing, compressionally unstable accretionary wedge that is dissected by transcurrent faults. {T}he wedge has been thinned and narrowed as a result of tectonic erosion. {T}he middle margin is stable by comparison and separated from the lower margin by the 220-km-long {A}wanui {F}ault. {T}his fault is a landward dipping, strike-slip, reverse fault. {T}he middle upper margin, including {E}ast {C}ape {R}idge ({ECR}), forms a deforming backstop with a sharp along-strike change in tectonic regime. {S}outh of 36°40'{S}, by transpression characterizes the {ECR} shear zone. {N}orth of 36°40'{S}, the {ECR} is marked by uplift, by extension and farther north by subsidence. {I}t is suggested that subsidence and subsequent tectonic erosion of the margin north of 35°50'{S}, in the wake of {H}ikurangi {P}lateua subduction, have broken the link between once continuous segments of the {ECR}-{T}onga {P}latform. {T}he unstable nature of the southern {K}ermadec wedge under compression, together with a comparison of its taper characteristics with those of modern convergent margins, implies that the wedge deforms under a relatively high internal pore pressure but high effective basal friction regime. {S}trike-slip deformation in the wedge is attributable to a relatively strong interplate coupling related to the buoyancy and ruggedness of the {H}ikurangi {P}lateau.
