Local Vertical Datum Height Discrepancy

Local vertical datum heights were updated on 14 January 2018 based on the Kaikoura earthquake geophysical deformation model. However, a further refinement based on post-earthquake observations is planned and will be implemented in the next few months.

To be notified of future updates sign up to 'Geodetic Database' updates on our mailing list: LINZ Geodetic Notifications

The Geodetic Database can be used to search for and download information about 128070 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 Android and Apple mobile devices.
