From here, you can search the Geodetic Database, download geodetic data or download a mobile application to find information on geodetic marks.

If you want to include geodetic marks in mapping systems, the LINZ Data Service holds simplified geodetic data layers as well as cadastral marks that are not included in the Geodetic Database.

We also provide coordinate conversion tools so that you can convert data from NZGD2000 to other coordinate systems.
