Landwrap - July 2025

Tēnā koe,  

Welcome to another month of activities, as you can see there is still plenty going on in the world of survey and titles.

Our thoughts are with those impacted by the ongoing weather events across the country, particularly in Marlborough, Nelson and Auckland. 

Changes to Landonline support pages

You may notice changes we’ve made to our Landonline support pages. As most functions have moved to New Landonline we’ve needed to adapt the content of our help. As part of that change, we’ve reviewed and updated our content to make it easier to read, and easier to find.

You might find pages you've bookmarked go to another page. We’ve redirected old pages to current pages with the most relevant and up-to-date information.

Please email any feedback or suggestions you have about our Landonline support pages to our Customer Support team.

Update default conveyancing professional (CP) in New Landonline

Dealing users can now update default conveyancing professional (CP) in New Landonline under My Profile.

Adding a conveyancing professional will let you quickly assign roles in a dealing.

For more information, see:

Update your default conveyancing professional

Web Search Releases

Display Survey Work

You can now display registered and approved surveys spatially in Web Search. This allows you to see a selected survey's:

• parcel extents
• boundary vectors, and their bearings and distances
• non-boundary vectors, and their bearings and distances
• marks, and their mark names.

You can display up to 10 surveys in the spatial map at one time.

For information on how to display surveys spatially, see:

Display survey work

Option to show fixed info panel

The info panel is now pinned to the bottom left of the spatial view by default in Web Search. This prevents it from obscuring your selected object on the map.

If you prefer the info panel to be attached to the spatial object you have selected, in Map settings toggle off Show fixed info panel.

For more information on editing map settings, see:
Map control toolbar

Territorial Authorities Layer

Territorial Authorities (TA) Layer has been added to Web Search under ‘Context layers’. The TA boundaries display as blue outlines, with an option to display the TA name.

Landonline – Survey Plan Generation

As we look to make New Plan Generation available to all Survey users at the end of July, we are keen to increase numbers of volunteers wanting to get involved in the pilot. This will help ensure the new functionality is working for you and improve your workflows without having to revert to legacy Landonline.

To express your interest in joining the Plan Generation pilot please email Landonlinefeedback@linz.govt.nz

Survey users will receive an invite to a Plan Generation webinar in the coming weeks; this is our chance to demonstrate the new functionality and address any questions you might have.

After the successful release of New Plan Generation, we will then look to confirm a date for the Legacy Landonline switch off.

While the New Plan Gen Landonline pilot was impacted by the Landonline outages of 20 May, our following investigation proved it was in no way a cause of the outage. Both Landonline and Plan Gen are stable and working well. LINZ will complete a debrief with key stakeholders on the outage in the coming weeks.

Landonline - Vector limit for surveys

We are receiving an increasing number of large legalisation and fee simple subdivision datasets that are pushing, or in some instances exceeding, the limits Landonline was designed for.

To provide certainty to you and your clients that there won’t be problems when preparing, lodging and processing the cadastral survey dataset (CSD) we are introducing a vector limit. The maximum number of vectors in a CSD must not exceed 3250.  This limit has been set by analysing lodgements over the last 5 years to understand which components of a CSD have the biggest impact on the Landonline system.

There have been just two CSDs in the last 5 years that have exceeded 3250 vectors, so we don’t expect this system constraint will impact many surveys.

The number of vectors in your CSD can be determined by clicking the ID check box in vector capture. 

If you are preparing a complex or large CSD (that may exceed 3250 vectors) then you should consider staging or chunking your survey into smaller CSDs.

If you want to discuss the matter with LINZ then please create a Survey Information Complex Request.

We will soon publish this as guidance on our website.

Height-limited boundaries guidance

Surveyors now have a new resource to help them comply with the Cadastral Survey Rules 2021. The new height-limited boundaries guidance brings together all the important information that was previously scattered across multiple pages.

As property rights become more complex and 3D cadastre concepts become more common, height-limited parcels are showing up more often.

Surveyors are encouraged to check out the guidance to stay informed and compliant. Feedback is most welcome.

Using AI to Improve Survey Data Accuracy

Land Information New Zealand (LINZ) partnered with 3Plus to explore how Artificial Intelligence (AI) could help us understand quality issues within Cadastral Survey Dataset (CSD) submissions. Around half of all CSDs currently have errors that are returned to the surveyor for correction, which slows down the process.

To do this, a Proof of Concept was done using AI to analyse past requisition data - these are the corrections LINZ sends back to surveyors. By identifying common patterns and themes in these corrections, the aim was to help us identify opportunities to target areas of non-compliance.

Using 3Plus’s AI platform, 3Pai, and a technique called Retrieval Augmented Generation (RAG) the data was securely analysed within LINZ’s dedicated AWS environment.

Here’s what was found:

• Speed: What would normally take weeks to analyse was done in just a few days using AI. This meant we could quickly refine our approach and get to insights faster.
• Flexibility: When subject matter experts (SMEs) spotted data quality issues, we were able to adjust our analysis on the fly. This iterative approach helped us improve the results as we learned more.
• Thoroughness: Instead of relying on anecdotes or small samples, we were able to do a full, objective review of the data to identify themes and patterns.
• Validation: We confirmed several existing assumptions within LINZ using solid, data-backed evidence. This enhances confidence that AI results are strong indicators of areas for focus in the future.

This Proof of Concept showed how AI can support the analysis of large amounts of data to identify areas for targeted interventions. There are no immediate impacts for the submission of CSDs but the insights have been fed into ongoing compliance work.

We will update you as we continue to explore potential AI solutions across all of our work in this space. 

Ngā Hapū o Ngāti Ranginui Claims Settlement Act 2025 Registration Guideline 2025

The Registrar-General of Land has published the Ngā Hapū o Ngāti Ranginui Claims Settlement Act 2025 Registration Guideline 2025 - LINZ OP G 01315.

The guideline covers the Ngā Hapū o Ngāti Ranginui Claims Settlement Act 2025 and is designed to be read in conjunction with the Treaty Claims Settlement Acts General Guideline 2018 – LINZG20786. The provisions of the Act took effect on the settlement date, 13 June 2025.

The guideline is primarily for Toitū Te Whenua employees with delegated authority to exercise registration functions under the Land Transfer Act 2017 and covers registration requirements and memorial formats for instruments lodged to give effect to the settlement.

Digital transformation on the horizon for maritime data

Our Landwrap survey indicated you might be interested in other LINZ related programme of work… so here’s some exciting news about funding allocated in the recent budget.

The Government has allocated $28.6M in Budget 2025 to develop high-tech navigational products that will transform shipping in New Zealand waters and make a critical contribution to maritime transport infrastructure.

The initiative will deliver the maritime data and services needed to support modern, freight-efficient, safe and environmentally sound ships that can travel to the region’s ports via the most efficient routes.
