This report updated Cabinet in November 2022 on the progress of SouthPAN, Toitū Te Whenua and Geoscience Australia’s joint initiative to improve the accuracy of global positioning signals in Australia and New Zealand.

This report updated Cabinet in May 2023 on the progress of Toitū Te Whenua and Geoscience Australia’s joint SouthPAN satellite initiative to improve the accuracy of global positioning signals in Australia and New Zealand.

The purpose of the 2023 New Zealand Geospatial Industry Profile Survey was to gain demographic and employment information about the geospatial industry in New Zealand.

The purpose of the survey was to determine the relationship between the permanent GNSS CORS site (WARK 50243M001), the invariant reference points (IVP) of the 12 metre (7377 50243S001) and 30 metre (7391 50243S002), radio telescopes capable of Very Long Baseline Interferometry (VLBI) observations.

The request relates to specific information about NZVD2016 Cadastral Vertical Control Marks and evidence to indicate how values attributed to these were derived.

The purpose of this standard is to ensure that the geospatial accuracy framework (LINZS25005) is consistently applied across LINZ cadastral survey and control system datasets

This fact sheet supersedes LINZG25702 Fact sheet - New Zealand Geodetic Datum 2000 Projections which was published in November 2007.

This fact sheet describes the Ross Sea Region Geodetic Datum 2000 (RSRGD2000).

The purpose of this standard is to both define the Ross Sea Region Geodetic Datum 2000 and detail the parameters that define it.

This report compares currently available transformation parameters for converting between NZGD49 (New Zealand Geodetic Datum 1949) and WGS84 (World Geodetic System 1984) coordinates.

With the establishment of a new datum comes a need to transform coordinates from one datum to the other as only a small number of marks have been surveyed in terms of both datums.

The 4 September 2010 Darfield (Canterbury) earthquake resulted in up to 5 metres of lateral slip along the previously unknown Greendale Fault (Figure 1) and associated ground surface displacements of up to about 2.5 metres within the surrounding region (Quigley et al., 2010, 2012; Beavan et al., 2010). Land Information New Zealand (LINZ) requires a way to correct and update the survey system for the effects of the earthquake.

These specifications relate to the provision of geodetic control maintenance to support the geodetic programme as required by the Cadastral Survey Act 2002 sec 7(1)(a) and (b).

This report examines height datum technologies and also looks at current international practice with respect to height datum issues. It presents some wider user perspectives before looking more specifically at the physical characteristics of New Zealand and the particular problems that it faces.

This report is the response to a brief from Land Information New Zealand (LINZ) to establish the economic foundation for funding a modern geodetic system for New Zealand.

This specification details the requirements for the reinstatement or replacement of marks identified as needing protection.

PowerNet field crews in New Zealand use SouthPAN to capture high-accuracy asset location data, reducing reliance on specialist surveyors and improving efficiency.

Page Bloomer make use of SouthPAN to consistently monitor, map, and manage their research and trial sites with greater efficiency and lower costs.

Information for Controllers, Recovery Managers, Intelligence Functions and GIS Teams.

The Official Information Act response provides details of LINZ confirming a datums height discrepancy and how third parties/the public were notified of the discrepancy.

This standard defines frameworks for specifying and classifying the accuracy of coordinates and the spatial relationships between them.

This standard defines the national vertical reference system: New Zealand Vertical Datum 2009 (NZVD2009).

Improved satellite based positioning to grow an innovative, safe and efficient New Zealand

This report discusses LINZ plans to update its requirements for providing access to the New Zealand spatial infrastructure.

This document presents some of the options and issues associated with the implementation of a deformation model, and proposes a more advanced model that can be used.

In support of LINZ’s PositioNZonLine automated positioning service we have completed a set of work with three major aims.

This paper considers the economic benefits that can be expected to arise from the upgrading of Land Information New Zealand’s (LINZ) network of Continuously Operating Reference Stations (CORS) to Real Time status and the costs of making that network available to the wider market.

This report describes the computation of NZGeoid09, a new gravimetric quasigeoid model for New Zealand, computed at the Western Australian Centre for Geodesy under contract #CON-SE-DSS-TS-45245-3 to Land Information New Zealand (LINZ).

This document describes the format used to publish the New Zealand Geodetic Datum 2000 (NZGD2000) deformation model.

New Zealand Geodetic Datum 2000 (NZGD2000) is aligned with the International Terrestrial Reference Frame 1996 (ITRF96) and referenced to epoch 2000.0. However the NZGD2000 coordinates also include the deformation due to earthquakes since 2000, which have been applied as ""reverse patches"" in the NZGD2000 deformation model.

The following document is a scanned image of the Department of Land and Survey Technical Circular 1973/32 that describes the technical details of the New Zealand Map Grid.

This guideline was developed to assist surveyors providing geodetic control survey data to Toitū Te Whenua.
