Auckland LIM Reports in 2026: What Changed with Natural Hazard Disclosures
If you've ordered a LIM report for an Auckland property recently — or if you're about to — you may notice it looks different from what you expected. Since October 2025, significant changes have been made to how natural hazard information appears on Land Information Memorandums across New Zealand. For Auckland specifically, there is more new data than most buyers realise.
Here is what changed, what it means, and how to make sense of it all.
§ 1.0What is a LIM report?
A Land Information Memorandum (LIM) is a report issued by your local council that summarises the information they hold about a specific property. It is required by law under the Local Government Official Information and Meetings Act 1987, and it is a standard part of property due diligence in New Zealand.
A LIM typically covers building and resource consent history, rates information, drainage and water supply details, and — critically for buyers — natural hazard information. Auckland Council is legally obligated to disclose any natural hazard information it holds about a property.
A standard Auckland LIM costs around $375 and takes up to 10 working days. Urgent processing is available for approximately $506 with a 5-working-day turnaround.
§ 2.0What changed in October 2025
Effective from 15 October 2025, new national legislation changed how councils present natural hazard information on LIM reports.
Clearer disclosures
Natural hazard information is now presented in a more standardised and understandable format. Previously, the way hazards were described varied between councils and could be difficult for non-specialists to interpret.
Landslide maps added
For the first time, Auckland LIMs include two landslide susceptibility maps - one for shallow landslides and one for large-scale landslides - based on Auckland Council's 2025 region-wide study (Technical Report TR2025/7). This is the first comprehensive landslide mapping for Auckland in almost 30 years.
Context statements
LIMs now include a context statement noting that the landslide maps are based on available regional data and are not intended for property-level assessment without further detailed investigation.
Free data also available
Auckland Council has made the same natural hazard information available online for free through the Flood Viewer and GeoMaps. This means you can check hazard layers before spending $375 on a LIM.
§ 3.0What a LIM tells you about flood risk
An Auckland LIM includes a “Natural Hazards – Flooding” map showing three potential flood hazard types.
Floodplains
Areas predicted to flood during a 1% AEP (1-in-100-year) rain event. If your property is within a floodplain, the LIM will show this. It can affect what you are allowed to build under Plan Change 120.
Flood Prone Areas
A formal designation indicating the property is potentially subject to flooding from various sources - overland flow, stormwater surcharge, and stream flooding. This is a legal disclosure that must be passed on to any future buyer.
Overland Flow Paths
Mapped corridors where stormwater flows across the surface during intense rainfall when the underground network reaches capacity. Restrictions apply to building or landscaping that would obstruct a flow path.
P Note · LIM data limitations
Auckland's flood maps are produced at catchment level using terrain data from 2016 — not individual property data. A new Auckland-wide LiDAR survey was flown in 2024 and updated models are being built. The absence of flood information on a LIM does not mean the property will not flood. It means no hazard has been identified in the council's current datasets for that location.
§ 4.0What a LIM doesn't tell you
A LIM is a snapshot of the information council holds at the time it is issued. It does not include:
A plain-language explanation of what each hazard means for you as a buyer.
Guidance on how the hazard might affect your insurance premiums or mortgage approval.
Recommendations for what to do about each finding.
An assessment of how Plan Change 120 rules apply to the property.
Any hazards the council does not currently hold data on - there may be risks not captured in their datasets.
This is the gap that a Know Your Risk NZ report is designed to fill. For $49 with instant delivery, you get a property-specific assessment of 7 hazard layers with plain-english explanations, practical action items, insurance and lending context, and a due diligence checklist. It is a complement to the LIM that helps you understand what the council data actually means for your decision.
§ 5.0The smart approach to due diligence
For Auckland property buyers in 2026, the most cost-effective approach is layered.
Free tools first
Check the Flood Viewer and GeoMaps before you even make an offer. This takes five minutes and gives you a quick read on whether the property has obvious hazard flags.
Know Your Risk NZ report ($49, instant)
If you are seriously considering a property, get a hazard report. You will see all 7 layers assessed with scores, explanations, and actions - before committing to the cost and delay of a LIM.
LIM report (~$375, 10 working days)
The formal legal document. You will want this for your solicitor and for the complete picture including building consent history and rates information.
Specialist assessment if needed
For properties with moderate-to-high hazard scores, a site-specific flood or geotechnical assessment by a qualified engineer gives you property-level data. This is the gold standard but costs $500-$2,000+ and takes time.
The total cost of steps 1–3 is around $424 and gives you a comprehensive hazard picture. That is less than 0.05% of an average Auckland property purchase, and it could save you from a decision that costs tens of thousands in unexpected insurance, declined finance, or reduced resale value.
