Toitū Te Whenua has established a network of sea level monitoring sites at 18 locations around New Zealand and Antarctica.

Toitū Te Whenua charts New Zealand's waters and coast to help commercial and recreational mariners safely navigate our waters.

We provide specialist geodetic products such as transformation grids and geodetic software. These are used for geodetic network adjustments and converting data between coordinate systems in New Zealand.

The Toitū Te Whenua PositioNZ network currently consists of 37 continuously operating reference stations (CORS) located throughout New Zealand (including the Chatham Islands) and Antarctica. Data is also available from several other CORS in New Zealand and Antarctica.
