This page contains information on the New Zealand Geodetic Datum 1949 (NZGD1949), which was the official geodetic datum for New Zealand until 1998. Like most datums of its era it was defined using astronomical observations to establish the coordinates of a relatively small number of fiducial stations.

A geodetic datum (plural datums, not data) is a reference from which spatial measurements are made. In surveying and geodesy , a datum is a set of reference points on the earth's surface against which position measurements are made, and (often) an associated model of the shape of the earth ( reference ellipsoid) to define a geographic coordinate system.

Traditionally, vertical datums have used classical survey methods to measure height differences (i.e. geodetic leveling) to best fit the surface of the earth. A geodetic datum is an abstract coordinate system with a reference surface (such as sea level) that serves to provide known locations to begin surveys and create maps. In this way, datums act similar to starting points when you give someone directions.

Geodetic data seem to help constrain seismological solutions at relatively long temporal periods (days to years) and intermediate spatial scales (within several fault dimensions of the rupture), as demonstrated for Landers by Wald and Heaton (1994).
