Next stage of vertical datum collection starts

The next phase of work to update & enhance the NZ vertical datum 2009 began on Saturday with flights from Timaru to collect South Island aerial gravity data.

The vertical datum provides a consistent reference point for measuring heights in New Zealand, its offshore islands & the continental shelf. Collection of aerial gravity data to improve accuracy began last year, when Land Information NZ, along with GNS Science and Victoria University, gathered airborne data from most of the North Island. More North Island flights will take place this year.

The project marks the first time airborne gravity data has been collected on such a scale in New Zealand. Land Information Minister Maurice Williamson said an accurate national vertical datum was essential to ensure the accurate integration of geospatial data and the determination of global change, such as rises in sea level.

“An updated datum allows the construction & infrastructure industries to use GPS receivers to more accurately calculate the height of any location. This is used for planning water & sewage infrastructure that follows downhill inclines.

“Once the data has been collected, the results will be analysed in preparation for the release of an improved datum in 2016. It will be accurate to within 3cm in developed areas.”

LINZ launches cadastral strategy

Land Information NZ launched its strategy to keep ahead of demands for cadastral information on Monday. Called Cadastre 2034, it’s intended to ensure that New Zealanders will be able to understand more easily where their rights in land actually are, and will be able to visualise those rights – and any restrictions & responsibilities – in 3 dimensions.

The cadastre is the system used to record & locate land boundaries. LINZ expects the use of digital technology in positioning, spatial databases & mobile devices to play a growing & significant role in New Zealand’s cadastre.

“New Zealand’s cadastre is world-class, giving New Zealanders certainty about exactly where their boundaries are when they buy, sell & make use of land. The cadastre provides a robust foundation for Government & private individuals to grow New Zealand’s economy, safeguarding nearly $700 billion in residential property wealth alone.

“However, society & technology are changing rapidly – people increasingly demand ready access to information, including cadastral information. They want more from the cadastre and want to integrate cadastral information with other spatially related information.

“The vision of Cadastre 2034 is for a broader cadastral system that enables people to readily & confidently identify the location & extent of all rights, restrictions & responsibilities related to land & real property.

“The strategy envisages advances in technology where cadastral information, including in 3-dimensional form, is available in real time through channels that meet user needs – including mobile devices that can be used for locating & depicting boundaries on the ground.

“Accurate geographical positioning will be available to everyone, and boundaries will be able to be visualised in a form that the layperson can readily understand – including in 3-dimensional form and closely related to such things as buildings, buried services, air space & seabed.”

GIS project to improve Maori land information

Published 6 March 2011

Courts Minister Georgina te Heuheu launched a project on Thursday designed to improve the presentation of information on Maori freehold land.

Mrs te Heuheu said the Maori land GIS (geographic information system) project would help Maori landowners, judges, researchers & local government: "The system offers a one-stop-shop source of information to assist Maori locate their land interests and identify opportunities to improve its management & development.

"This is a far cry from the days gone by when Maori landowners would have to pore over heavily bound court records to get the most basic information of their ownership."

The new system will provide accurate geospatial information on Maori land blocks and be accessible through an internet portal for search & download. The portal will provide a much greater range & level of detail than previously available and will be viewable in te reo Maori.

“The portal uses Google technology and information from LINZ to provide instant visual pictures & maps of the type & location of land, which can then be used to compile reports. One of the many benefits is that the system has been future-proofed and designed so it can be updated as technology advances, allowing the potential to add layers of information.

"This capability will empower Maori landowners and enable them to engage in good decision-making, sound management & positive strategies to utilise & develop their land.”

99% of Maori freehold land now on LINZ register

Published 31 March 2010

99% of Maori freehold land – 27,000 land blocks – have been registered with Land Information NZ (LINZ), concluding a 5-year project between the Ministry of Justice and LINZ to register all outstanding Maori Land Court orders relating to Maori land ownership.


Courts Minister Georgina te Heuheu said on Monday the project was highly significant for Maori: "It has resulted in the reversal of anomalies between the Land Transfer registry & the Maori Land Court registry. It creates equal recognition & quality of title for Maori freehold land in the same way as general land. This provides a sound platform for the economic developmental aspirations of Maori landowners."


Land Information Minister Maurice Williamson said the project had improved the ability for Maori landowners to set up economic development initiatives where a formal certificate of title is required: "Access to finance, title aggregation, easements & access issues can be worked through now land blocks have parcel identification."
