National Height Network
The NHN ensures that important precise levelling control marks are retained and that geometric heights are determined for new control marks when they are established. This enables users to connect their datasets to the official geodetic datum.

Local mean sea level datums (LVDs)
Many heights around New Zealand have been referenced to a local sea level, or local vertical datum (LVD). In the past this was the most practical method of determining a height reference point, but more robust height references are now available to replace these.

New Zealand Transverse Mercator 2000 (NZTM2000)
New Zealand Transverse Mercator 2000 (NZTM2000) is the projection used for New Zealand's Topo50 1:50,000 and other small-scale mapping. It is the recommended projection for use within mainland New Zealand.

Coordinate and height accuracy
In New Zealand the accuracy of coordinates and heights is classified using a system of orders. These indicate the expected accuracy of specific components so users can assess the reliability of their geospatial data.
