LINZ Geodetic database

Kaikoura Earthquake information for Surveyors

Information about the Kaikoura Earthquake and its impact on surveyors is available on the LINZ website at This page will be updated periodically as new information becomes available.

Coordinates streamed from the PositioNZ stations have not been updated for Kaikoura Earthquake movements

The PositioNZ-RT mountpoint coordinates have not been updated to account for the recent earthquakes. Please be mindful of this if you are using PositioNZ-RT in the affected area which spans from Christchurch to Wellington. It may be some time before streamed coordinates are updated, however, post-earthquake NZGD2000 coordinates will be available within the next week on the LINZ Data Service if you require them.

The Geodetic Database can be used to search for and download information about 124322 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.
