Land Environments of New Zealand (LENZ) is a classification of fifteen climate, landform, and soil variables chosen for their relevance to biological distributions. Classification groups were derived by automatic classification using a multivariate procedure. Four levels of classification detail have been produced from this analysis, containing 20, 100, 200, and 500 groups respectively.
Purpose
Detailed descriptions of the input data layers, the methods, and the resulting classification groups are contained in two publications: Leathwick et al. 2003. Land Environments of New Zealand. David Bateman Ltd, Auckland; and Leathwick et al. 2003. LENZ Technical Guide, Ministry for the Environment. This layer is the first with only 20 environments.
Supplemental Information
This dataset was converted to Shape file polygons from the native Grid format. Fundemental data layer is interger. Attatched attribute table identifies LENZ level IV groups and their average environment.

Process Description
Land Environments of New Zealand (LENZ) was derived by combining data from the Land Resource Inventory (LRI) database, thin plate spline surfaces fitted to long-run average climate data from climate stations throughout New Zealand, and a slope layer computed from a 25 meter DEM derived by Landcare Research from 20 m contour data used in the production of NZMS 260 series topographic maps.
