The Central Record of State Land (CRoSL) is an innovative tool that will support government agencies, local agencies and councils to better understand who owns Crown Estate and State Land, and how it is being used.

Having this information in a central place will improve the efficiency of land transactions and significantly reduce the amount of time and money spent on researching land ownership.

CRoSL prototype

Members of our Crown Property team are working with other agencies to design and implement CRoSL. A prototype has been developed to demonstrate the potential of the tool using just a small amount of data.

View the CRoSL protoype

We would appreciate your feedback on this prototype. Please take some time to fill out our survey.

The prototype already shows:

  • 218,675 parcels of land
  • 27.9% have no title
  • 87.4% have a management entity identified
  • 162 different management entities have been identified
  • The top 4 agencies (Housing NZ, DOC, LINZ and Auckland Council) combined manage 61% of identified parcels

The full tool is expected to be released in 2020.

Stakeholder Engagement

Detailed discussions with other agencies that will use CRoSL as part of the design phase.

July 2019

Prototype released

The prototype is released on 5 July. It has been built using ArcGIS using information primarily from Landonline. The number of fields available is not representative of the scale of information the final tool will hold. We will be seeking feedback from agencies about the prototype.

Mid to late 2019

Design and development

This phased includes gathering feedback on the prototype to inform the next design stage. We will be working with them to co-design the process for how we capture their data to populate the final tool.

Early to mid‑2020

Full solution

The full solution will be built to sit alongside Landonline. We will be using the approach and learnings from the STEP project to ensure that the ability to integrate CRoSL into the next generation of Landonline.

2020 onwards

Ongoing maintenance

Once we have released the full solution we will still need to collect and cleanse the data required to make it a complete set of information. We will also be maintaining CRoSL to ensure it remains fit for the future.

Background to the project

A central record of state land has been discussed before by LINZ. Gathering the data from multiple Government agencies was more challenging than expected so the project was put on hold. Following recent changes to Crown Property within LINZ, and the increasing need for a central record of state land LINZ is now committing the time and resources to deliver this project as swiftly as possible.

Building on existing systems

We plan to use an existing LINZ system for the central record to reduce build costs. The exact system hasn’t been confirmed yet, as we are still finalising the requirements. Costs will vary based on the chosen system.

Making information available, and working across agencies

CRoSL uses information that is held by all agencies, and is also available via an official information act request. While some parts of the record may be sensitive and will not be made available, the intention is to make as much as possible available to the public.

When it comes to creaing once source of information, there are various ways to link data across datasets. The exact approach that we will use will be based on what we learn from agencies as part of the stakeholder engagement and requirements gathering.

Agencies will be involved in the co-design of the central record, in conjunction with LINZ.

Future integration with Landonline

Rebuilding Landonline is a five-year programme of work, and a central record is not included in Tranche 1 or 2. Landonline is a national record of title for land in New Zealand. We are designing the full CRoSL solution to align with the data model so it can be incorporated at a later date.
