New Zealand Property Spine
The current LINZ national property-data programme is the New Zealand Property Spine. Older references to a LINZ property pilot should be read as programme history, not the current product name.
The Property Spine is designed to connect common property components such as:
- address
- title
- cadastral parcel
- buildings
- National District Valuation Roll information
using a property identifier and explicit relationships rather than pretending these records are the same object.
Access in 2026
LINZ states that Property Spine data is delivered through the LINZ Data Service in the NZ Properties dataset and includes the National District Valuation Roll. Access is currently limited to specified Public Service departments, other executive/legislative public bodies and statutory Crown entities.
That means a hapū trust, iwi organisation, researcher or ordinary GIS user should not plan a workflow around direct access to NZ Properties unless they separately meet LINZ's access criteria through the relevant organisation/contract arrangement.
Open LINZ parcel, address, building and other datasets remain useful independently.
Why the model still matters
Even if you cannot access the controlled dataset, the Property Spine explains an important GIS principle: a property is a relationship among several records, not automatically one polygon.
It helps explain why:
- title counts differ from parcel counts
- addresses can be many-to-one or one-to-many with land units
- buildings need their own identifiers
- rating information can group land differently
