High class land for food production North Island 2012
Environmental Reporting, Ministry for the Environment and Statistics New Zealand
"This data identified areas in the South Island that have been classified as being the most productive for growing food. It supports most crops across New Zealand. Expanding lifestyle blocks and urban areas reduce the availability of high-class land for commercial crop growing, and this land is unlikely to be returned to primary production. This affects our commercial food-production capacity.
This data set relates to the ""High-class land for food production"" measure on the Environmental Indicators, Te taiao Aotearoa website."
