The New Zealand Vertical Datum 2009 has been superseded by the New Zealand Vertical Datum 2016 (NZVD2016).

NZVD2009 was the official national vertical datum for New Zealand from September 2009 until June 2016.  It provided a nationally constant vertical datum for New Zealand, for the first time. It enabled the calculation of heights in the normal-orthometric height system using observations from GNSS (Global Navigation Satellite System) equipment, such as GPS.

NZVD2009 was defined by the NZGeoid2009 geoid, covering the New Zealand continental shelf area between 160°E –170°W and 25°S – 60°S.

Offsets were provide to transform heights from 13 major local vertical datums to NZVD2009. These offsets are listed below.
