The LINZ Data Service provides free access to bulk data relating to property ownership and boundaries. All property ownership and boundaries data is sourced directly from Landonline, our title and survey management system, and is updated every week.
Simplified property ownership and boundaries data
The LINZ Data Service provides a selection of simplified geospatial and non-geospatial (tabular) cadastral survey and property title datasets. These datasets contain information types (attributes) that are most useful for most data processing, GIS viewing and analysis.
- See a list of all property ownership and boundaries datasets on the LINZ Data Service.
- Download the LDS Property and Ownership Simple Tables Data Dictionary to understand the data relationships.
- Overlay the NZ Parcel Boundaries map service in your web, mobile or GIS application.
Complex property ownership and boundary data
The Full Landonline Dataset is designed to cater for Toitū Te Whenua customers who need to access large volumes of complex survey and title data on a regular basis. Expertise in reading, transforming and analysing large volumes of complex data is required to successfully understand and use this data.

- Download the LDS Full Landonline Data Dictionary and Models document to understand the relationships between the data.
Types of property ownership and boundary data
Parcel information is used to define property land rights and boundaries in New Zealand. Additional datasets relating to these parcel polygons includes references, surveys and titles, appellations and statutory actions.
Property titles data includes information about ownership, all estates, encumbrances and easements that affect a piece of land, such as mortgages, leases and right of ways.
LDS includes a series of tables that provide more detailed titles information, including a link table to make the association between parcels and titles.
Survey and coordinates
Survey and coordinates data provide cadastral survey observations, monuments (marks) and survey plan references. These datasets provide the definition for the cadastral system.

Title to Parcel Association
The land titles and cadastral survey registries used to be separately managed, and the linkages between them relied on users interpreting the respective system appellations. Landonline brought the systems together in 2001.
As part of this implementation, the data from the historical survey and title papers systems were digitised. This conversion left inconsistencies and gaps, so a digital link between the title and survey parcels records was not possible in all instances. Since 2021, Toitū Te Whenua has been improving this title to parcel match.
An association table was created in Landonline to allow more links to be created than Landonline could previously manage. This table supplements the original links, such as by enabling unit titles to be associated with a parcel. Where the original data was incomplete or missing, some links have come from non-official sources.
These associations are now used in all LDS layers that utilise title information, meaning that more than 99.9% of titles are now linked in some form to a parcel. We believe that the vast majority of these additional associations are correct, but there is a small chance of an error. If you find a mis-linked title/parcel combination please contact Toitū Te Whenua customer support.
The few titles which are unlinked either require investigation to make the correct link or are related to particular situations where they can’t be linked to parcels. An example of the latter would be a title of the type 'Records Embodied in the Register' that relates to mining licences over a large region of the country.
