Property, ownership and address data

The LINZ Data Service provides a selection of simplified geospatial and non-geospatial (tabular) cadastral survey, property title and electoral datasets. 

These layers in the LINZ Data Service provide access to datasets that are easy to use and have attributes that are most useful for most dta processing, GIS viewing and analysis. These simple layers and tables are derived from the more complex Landonline data model.

The following layers provide parcel information which is used to define property land rights in New Zealand. Additional information relating to these parcel polygons includes references, surveys and titles, appellations and statutory actions.

The following tables provide de-aggregated statutory actions and affecting surveys information for parcels. Note: this data is already provided in an aggregated form within the above parcel layers:

You can also access layers and tables that provide property title data. If you sign up the Restricted Owners Group you can also access the ownership details relating to the title.

These simple layers and tables provide property title records that are linked to spatial parcels:  

These tables provide more detailed titles information, including a link table to make the association between parcels and titles:

These layers provide electoral road and street address data that is currently maintained within Landonline:

These simple layers provide cadastral survey observations, monuments (marks) and survey plan references. These datasets provide the definition for the cadastral system.

These simple layers provide the characteristics and extents for spatial adjustment of survey observations and marks within Landonline:

For more information about these layers and tables that make up this dataset refer to the support documentation in the LDS Property and Ownership Simple Tables Data Dictionary.

Title to Parcel Association

Historically the land titles and cadastral survey registries were separately managed. The linkages between these systems initially relied on people interpreting the respective system appellations. In 2001 the Landonline system was implemented which brought these two systems together. As part of this implementation an electronic conversion of the data from the historical survey and title papers systems was completed. This conversion was not complete and left many data inconsistency or gaps. This meant that a digital link between the title and survey parcels records was not possible in all instances. LINZ has a title and parcel linking project underway that is improving this title parcel match further. 

A new association table has also been created in Landonline which enables more links to be created than the original Landonline functionality and data structures was able to. This table supplements the original links (for example, enabling unit titles to be associated with a parcel). A small number of these links come from non-official sources where the original data was incomplete or missing.  The new associations are now used in all LDS layers that utilise title information meaning that more than 97% of titles are now linked in some form to a parcel. In most cases, LINZ believes these additional associations to be correct; however there is a small chance there is an error. If you find a mis-linked title/parcel combination please contact LINZ via customer support or tell us about it via the LDS layer comment functionality.

Restricted data

Two data layers - those that provide information on the owner of a property title - have a customised license which you need to accept before being able to access this data.

This license enables LINZ to request that you change or delete such data to protect the privacy of personal information (owner names). If you have forwarded this information on to a third party, you must do so under the same conditions as the original license and ensure that the data has been changed or deleted.
