Abstract
The relationship between the GRS80 ellipsoid and the New Zealand Vertical Datum 2016 (NZVD2016) is modelled by the New Zealand Quasigeoid 2016 (NZGeoid2016). The relationship value is represented by the attribute “N”, in metres.
This relationship and NZVD2016 is formally defined in the LINZ standard [LINZS25009](http://www.linz.govt.nz/regulatory/25009).
NZGeoid2016 can be used to convert New Zealand Geodetic Datum 2000 (NZGD2000) ellipsoidal heights to NZVD2016 normal-orthometric heights.
The conversion value is represented by the attribute “N”, in metres.
NZGeoid2016 is published on a one arc-minute grid (approximately 1.8 kilometres) over the New Zealand continental shelf (160° E to 170° W, 25° S to 60° S).
NZGeoid2016 was calculated by enhancing the EIGEN-6C4 global gravity model with, terrestrial, ship-track, satellite and airborne gravity data. GPS-levelling observations were not used to compute NZGeoid2016.
**Users may also be interested in transforming heights to any of the 13 historic local vertical datums used in New Zealand using the appropriate datum relationship grid displayed in the [NZ Height Conversion Index](http://data.linz.govt.nz/layer/3419).**
More information on these transformations is available [on the LINZ website](http://www.linz.govt.nz/data/geodetic-services/coordinate-conversion/converting-between-nzvd2016-nzgd2000-and-local-vertical-datums).
Purpose
The New Zealand Geoid 2016 (NZGeoid2016) is the reference surface for the New Zealand Vertical Datum 2016 (NZVD2016).

From June 2016 NZVD2016 has replaced New Zealand Vertical Datum 2009 as New Zealand’s official vertical datum. The reference surface for NZVD2016 is NZGeoid2016.
NZGeoid2016 is published on a one arc-minute grid (approximately 1.8 kilometres) over the New Zealand continental shelf (160° E to 170° W, 25° S to 60° S).
NZGeoid2016 was calculated by enhancing the EIGEN-6C4 global gravity model with, terrestrial, ship-track, satellite and airborne gravity data. GPS-levelling observations were not used to compute NZGeoid2016.
