Orthometric height orders

On 3 September 2014 the orthometric height order of approximately 10000 geodetic marks was updated from 2V to 3V. This better reflects the likely accuracy of these heights. None of the heights has changed. The previous 2V heights can still be viewed by selecting the 'Historical values' link next to the current height of a mark.

The Geodetic Database can be used to search for and download information about 120733 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.
