Three dimensional (3D) seismic reflection data were collected in 2014 at the Tuaheni Landslide Complex, east of New Zealand's North Island. Data were collected using GEOMAR's 3D P-Cable seismic system, deployed from New Zealand's research vessel Tangaroa during voyage TAN1404. The dataset has been processed through to a 3D Kirchhoff time migration using Globe Claritas processing software at GNS Science. The spacing between successive inlines is 6.25 m and between successive crosslines is 3.125 m. See following publication for details about data processing: doi:10.1029/2017TC004906.
