The LINZ PositioNZ network consists of 39 continuously operating reference stations (CORS) located throughout New Zealand (including the Chatham Islands) and Antarctica.
Landonline coordinate update has been implemented
A new version of NZGD2000 (version 20171201) was released on 14 January 2018. The deformation model in this version includes "patches" for the movement due to the Kaikoura earthquake of 14 November 2016 and subsequent post-seismic deformation. As a result NZGD2000 coordinates have been changed in the area most affected by the earthquakes.
The updated datasets within LINZ Data Service will be available on the 22 January while the streamed PositioNZ-RT coordinates will now be updated on 23 January 2018.
The network collects Global Navigation Satellite System (GNSS) data for the purposes of monitoring the New Zealand Geodetic Datum 2000 (NZGD2000), updating the national deformation model, and maintaining New Zealand’s relationship to the International Terrestrial Reference Frame (ITRF). LINZ also provides data to the International GNSS Service (IGS) from six of our stations which contribute to more accurate estimates of GNSS satellite orbits and positions.
The PositioNZ network enables users to position points with an accuracy that approaches a few centimetres relative to NZGD2000 both horizontally and vertically. The network collects data from the United States Global Positioning System (GPS) and the Russian GLONASS satellite constellations.
LINZ provides static GNSS data in the form of RINEX through the PositioNZ RINEX Archive, real time RTCM streams through PositioNZ-RT and a post processing service called PositioNZ-PP. These products and services are used by surveyors, engineers, geospatial professionals, scientists and commercial providers. All data is freely available for reuse under LINZ copyright.

PositioNZ Post Processing Service (PositioNZ-PP)
The GNSS post processing service is a free automated service for processing GNSS data to obtain co-ordinates in terms of NZGD2000 and ITRF2008.
