National soil data
The key soil information source at national level is S-map Online. S-map is Manaaki Whenua’s ongoing project to map New Zealand's soil resources. The information is provided at a nominal 1:50,000 scale in most cases, so make sure you do not use it for paddock-scale decision-making without further investigation on-site.
How to access: Following a free of charge registration you have instant access to soil factsheets containing soil class and property information for your area of interest. A set of S-map layers is available from the LRIS portal for download and analysis.
The digital soil map of New Zealand
The tool also allows you to create custom soil maps and download soil factsheets for specific locations.
