LINZ Geodetic database

Large Geodetic Coordinate Update Planned

An update of approximately 80,000 geodetic coordinates is planned for 29/30 June. This will improve the accuracy of coordinates and account for the effects of the 2013 Cook Strait and Lake Grassmere earthquakes and the 14 February 2016 Christchurch earthquake.

The Geodetic Database can be used to search for and download information about 123089 geodetic marks in New Zealand, the Chatham Islands, and Antarctica.

The database can be accessed by searching on a map or by using a text only version. The geodetic database is also available on Apple mobile devices. The Android geodetic mark app is currently under redevelopment to be compatible with modern Android operating systems. It is expected to be released in mid 2016.
