This layer contains all individual vector layers of the NZTopo250 available through the LINZ Data Service with the exception of the contour layer (https://data.linz.govt.nz/layer/50159-nz-contours-topo-1250k/) which can be downloaded separately.
This grouping of NZ Topo250 layers will allow you to quickly view and download this collection of related layers.
See the Topographic Data Dictionary (http://www.linz.govt.nz/data/linz-data/topographic-data/topographic-specifications) for detailed information about each layer. Background information, including update history, is also available (http://www.linz.govt.nz/land/maps/linz-topographic-maps/topo250-maps).
LINZ and our predecessors have been responsible for national topographic mapping in New Zealand for more than a hundred years.
The first digital data at 1:250,000 scale was created in the late 80's by scanning the 1:250,000 maps that existed at the time (known as the NZMS 262 series, which replaced the earlier NZMS 18 series)
The NZMS 262 series were generalised from the NZMS 260 series.
The Topo250 map series are compiled from a mix of information from the NZMS 262 series, and that from the Topo50.
LINZ releases regular updates of the Topo250 maps and data. Details are posted at http://www.linz.govt.nz/docs/topography/250-sheet-history.xls
