LUNZ is a comprehensive land use dataset for New Zealand that was created by Landcare Research using information from AgriBase, LCDB2, LENZ and MAF monitor farm types. The dataset was created as part of the CLUES project (Woods et al, 2006).
The smallest unit of observation is a sub-farm: a piece of land on a specific farm with a unique land cover type. As AgriBase is not comprehensive, land use for farms with missing information had to be inferred using other sources of information. (Motu restricted dataset 2.)
