Description:
The New Zealand Quasigeoid 2016 (NZGeoid2016) is the official gravimetric model for New Zealand. It is distributed by Land
Information New Zealand (LINZ), it is produced 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) and it is referred to the GRS80 ellipsoid. It was calculated by enhancing
the EIGEN-6C4 global model using a combination of terrestrial, ship-track, airborne and satellite based gravity observations,
while GPS-levelling observations were not used. The NZGeoid2016 model has an expected accuracy of better than 3 centimetres based
on comparisons with GPS-levelling in urban areas.
