Heights for more than 48,500 geodetic marks in terms of NZVD2016 (New Zealand Vertical Datum 2016) are available from Landonline and the geodetic database.
This means it will be much easier for surveyors to connect their surveys to marks in terms of the official national vertical datum.
Published NZVD2016 heights have been derived from a single least squares adjustment which combines all geodetic GNSS observations collected since the 90s, with the first order levelling networks. This means that published NZVD2016 heights are nationally consistent and have been assigned orders according to their appropriate tier and class.
NZVD2016 heights 3V or better can now be found at ~200m spacing in most urban areas and ~2km in rural areas.
The Surveyor-General encourages surveyors to use the new vertical datum for all surveys including cadastral surveys.
NZVD2016 was released in June 2016, and more information is available in the New Zealand Vertical Datum 2016 section of our website.
LINZ has also produced a number of tools to provide access to the datum such as the online vertical datum converter.
