The LINZ Data Service provides free access to data relating to property ownership and boundaries. All property ownership and boundaries data is sourced direct from Landonline, our title and survey management system, and is updated every week.
If you want easy to use data, our simplified property ownership and boundaries datasets will meet your needs. If you’re a data guru who needs complex property ownership and boundaries data, then the Full Landonline Dataset is for you.
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.
How you can use property ownership and boundaries data
Our property ownership and boundaries data can be:
- used to visualise the land parcels and ownership across New Zealand
- combined with Council data to provide information on property, services and recreational facilities, and much more.
Special license for personal data
Access is free and most data is available under a Creative Common license. However, datasets containing personal data, such as those that contain information on the owner of a property title, have a customised licence that you need to accept before being able to access this data.
Title to Parcel Association
In the past 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 brought these 2 systems together. As part of this implementation the data from the historical survey and title papers systems were electronically converted.
This conversion was not complete and left many data inconsistencies or gaps, so a digital link between the title and survey parcels records was not possible in all instances. Toitū Te Whenua is currently working on improving this title parcel match.
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 could manage. 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, we believe these additional associations to be correct; however there is a small chance of an error. If you find a mis-linked title/parcel combination please contact Toitū Te Whenua customer support email or tell us about it through the LDS layer comment functionality.
