New Zealand Aquifer Potential Map Version 1.0

The Aquifer Potential Map is a preliminary map (version 1.0). This work was carried out as part of the GNS Science Groundwater Resources of New Zealand research programme, and future plans within this research programme include the refinement and update of this map. In its current form, the map is considered suitable for refining surficial aquifer boundaries on the regional scale where these boundaries have not been updated since 2001. Future updates of the dataset will reduce the uncertainty and extend the applicability of the data set. The New Zealand 1:250,000 geological map (QMAP) lithological and chrono-stratigraphic information (i.e., main rock type; geological age; and secondary rock type) were used to carry out a nationwide assessment of surficial hydrogeological units and their properties. A number of subsequent map products were produced. The work is described in Tschritter et al. 2017. One of these, the Aquifer Potential map, shows a good match with the most recent New Zealand national aquifer boundary dataset of Moreau and Bekele (2015). Additionally, the Aquifer Potential map provides a quick and simple way to communicate basic large-scale hydrogeological information. DOI: Cite as: GNS Science. (2017).
