The Toitū Te Whenua PositioNZ Post Processing Service (PositioNZ-PP) is a free, automated service that processes global navigation satellite system (GNSS) data to accurately determine the coordinates of a static point.

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.

We manage and maintain physical geodetic marks throughout New Zealand (including the offshore islands) and Antarctica. This section provides information about accessing mark information and downloading mark data.

Toitū Te Whenua and Geoscience Australia explored the feasibility of SouthPAN in an 18-month trial focused on 10 sectors in Australia and New Zealand. The trial confirmed the benefits, including improved GPS accuracy, improved signal integrity, and reduced commercial costs and infrastructure investment.

New Zealand and Australia have jointly confirmed the feasibility of SouthPAN. Between 2017 and 2019, a trial established that SouthPAN improved GPS accuracy, improved signal integrity, and reduced commercial costs.

This page provides information required to connect to the PositioNZ Real Time Service. Access to the network is free, but users need to register.

Wherever industry relies on accurate positioning information, SouthPAN will make a difference. It will support innovation in sectors as diverse as primary production, transport, construction, forestry and aviation.

Signals from SouthPAN L1 SBAS can be tracked and processed by many GNSS receivers compatible with WAAS, EGNOS and other SBAS.

GNSS equipment manufacturers, solution providers and end users should use the SouthPAN service definition documents to implement the early Open Services from SouthPAN on their devices.

To download all geodetic mark data, use the LINZ Data Service.

We welcome feedback about the safety, maintenance, coordinate or height information of any survey mark. Let us know if marks have been damaged or destroyed, and suggest where new marks should be installed.

Every day, people use location information to make important decisions. Demand for people with geospatial capabilities is growing both in New Zealand and overseas.

The NRF provides the connection between national geodetic and vertical datums, and international reference systems.

The CVN provides the street-level control marks that are used by surveyors to connect cadastral surveys to the official vertical datum (NZVD2016).

New Zealand’s survey control system comprises physical control marks and information about them to enable the coordinates of other points to be determined. The control system is segmented into six control networks which provide control marks for specific purposes.

Our geodetic mark data can be accessed and downloaded from the LINZ Geodetic Database, LINZ Data Service or KML Service.
