This dataset has been superseded by a new edition (2nd edition) available here: https://data.gns.cri.nz/metadata/srv/eng/catalog.search#/metadata/647B1A4A-5E23-4FEE-80D0-260C6A6F49EC.

This dataset contains the 1:1 000 000 geological units data for New Zealand. The dataset is a product of the Geological Map of New Zealand 1: 1 000 000 project and was produced by GNS Science. It represents the most current mapping of the geology of New Zealand in a single dataset at a scale of 1:1 000 000. The dataset is stored in an ESRI vector geodatabase and exported to ArcGIS Server. The dataset comprises polygons with each polygon having attributes describing the type of geological unit, its content, name and age. It complies with the GeoSciML Portrayal standard for GeologicUnitView. The outcrop surface (map horizon) on which the features are mapped is the Earth surface. The fields required by the GeoSciML Portrayal standard were populated using the CGI Controlled Vocabulary (2012-11).

The dataset is available for purchase as feature classes in ESRI file geodatabase and shapefile GIS formats and freely consumable as a layer in Web Map Services and Web Feature Services from ArcGIS Server.
