Mapping Aotearoa New Zealand

GNS Science has unrivalled expertise in geological mapping, with over a century of experience in producing high quality geological maps of New Zealand. We have over a century of experience in producing high quality geological maps at national, regional and local scales.

Our focus is gathering knowledge on the distribution, composition and origin of geological units of our continent.

All of our geological maps, and their underlying digital data where applicable, can be obtained through our webshop, many as free downloads. A geological web map application enables viewing of our national 1:1,000,000 and 1:250,000 geological datasets and these data layers can be also be used with mainstream GIS software by calling our web services.
