Kaikoura Earthquake information for surveyors

Information about the Kaikoura Earthquake and its impact on surveyors is available on the LINZ website. This page will be updated periodically as new information becomes available. Post-earthquake coordinates are available via the LINZ Data Service.

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.

The Geodetic Database can be used to search for and download information about 126856 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 early 2017.
