New Zealand Environmental Data Stack (NZEnvDS) comprises a set of 72 spatial layers for environmental modelling and site characterisation. NZEnvDS includes the layers that informed the Land Environments of New Zealand (LENZ), additional layers generated for LENZ that were never publicly released, and additional layers generated since, all covering mainland New Zealand and surrounding inshore islands. The original/top copy of the dataset is available at (https://doi.org/10.7931/m6rm-vz40), but the layers are reproduced here for ease of access. See (https://newzealandecology.org/nzje/3440/) for a publication describing NZEnvDS. Calculated as the mean of the monthly LENZ windspeed layers for the years 1950–1980 (Leathwick et al. 2002).
