This collection of datasets comprise the 'Tectonic map of Te Riu-a-Māui / Zealandia' 1:8 500 000 data compilation. It contains the geospatial layers showing the main tectonic features and bathymetric environment of the region surrounding Te Riu-a-Māui / Zealandia.

This dataset is an interpretation of geophysical characteristics derived from aeromagnetic data for the area encompassed by this map. The dataset comprises arcs with each arc having attributes describing the type of anomaly represented and the geological feature inferred.

This dataset spatially represents sample locations where geochronological dating methods provide an assessment of age of the sampled material.

This data layer spatially represents depositional unconformities within the geological materials, divided by age, present at the surface interpreted from seismic data. The data structure complies with the GeoSciML 4.1 standard where relevant and uses the relevant CGI Controlled Vocabularies.

This layer shows the location of the interpreted subsurface extent of the subducted western and southern edges of the Hikurangi Plateau. The layer was newly-compiled for, and is part of, the 'Tectonic map of Te Riu-a-Māui / Zealandia' 1:8 500 000 dataset.

This collection of datasets comprises the 'Geology of the Hyde-Macraes Shear Zone and Waihemo Fault Zone area' 1:50 000 compilation of geological data covering a part of of East Otago and extending off shore to the Karitane Canyon.

This layer shows the observed and calculated velocities of active plate motions at selected surface locations in and around Te Riu-a-Māui / Zealandia. Velocities are shown relative to a fixed Australian Plate using the Global Strain Rate Model version 2.1. The layer was newly-compiled for, and is part of, the 'Tectonic map of Te Riu-a-Māui / Zealandia' 1:8 500 000 dataset.

This dataset is an interpretation of geophysical characteristics derived from aeromagnetic data for the area encompassed by this map. The dataset comprises polygons with each polygon having attributes describing the type of anomaly represented and the geological feature inferred.

This dataset is an interpretation of geophysical characteristics derived from electromagnetic data for the area encompassed by this map. This dataset spatially represents an interpretation of areas of consistent electromagnetic response at 8200 Hz. The dataset comprises polygons with each polygon having attributes describing the type of anomaly represented and the geological feature inferred.

This data layer spatially represents 100 m thickness-contours of the Cretaceous-Cenozoic geological materials between the seabed and the geological basement, interpreted from seismic data.
