Vertical datum relationship grids allow the transformation of local vertical datum heights to NZVD2016. These transformation grids were calculated by using observation points with both an ellipsoidal and a normal-orthometric height.

Following a major earthquake, there is often an urgent need for geodetic coordinates, particularly heights, to help re-establish critical infrastructure such as stormwater and wastewater systems.

You and your advisors can meet with us before you submit your application for consent.

Geoids and quasigeoids are reference surfaces that accurately represent the Earth’s shape and gravitational field. By collecting gravity data (which differs with latitude, elevation, geology and time), gravity field models are created to compute the geoid, which is then used as reference for a vertical datum.
