12 Red Flags Every Home Buyer Must Check
Buying a property in New Zealand? Learn exactly what to look for in a LIM report, the most common red flags, and how to avoid costly mistakes before settlement.
Buying a property in New Zealand is exciting. But before you sign a sale and purchase agreement, there is one document that could save you from making a very expensive mistake: the LIM report.
Every year, buyers discover hidden issues after settlement that could have been identified during due diligence. Flood risks. Unconsented renovations. Land instability. Future road designations. Insurance challenges. Many of these warnings are buried inside a LIM report — and most buyers don't know what they're looking for.
This guide explains exactly what to look for in a LIM report in New Zealand and the biggest red flags that should never be ignored.
What Is a LIM Report?
A LIM (Land Information Memorandum) report is an official document issued by the local council under Section 44A of the Local Government Official Information and Meetings Act 1987. It contains all information held by the council about a property, including:
- Building records and consents
- Hazard information
- Planning and zoning restrictions
- Drainage and infrastructure records
- Land-related risks
- Rates and valuation information
Think of it as the council's history file for the property. It must be provided within 10 working days of request, and councils are required to include all information they hold that is relevant to the property.
Why Reading a LIM Report Properly Matters
Many buyers make the mistake of treating a LIM report as a simple checklist. In reality, a LIM report is often 50 to 300+ pages long and may contain information that directly impacts:
- Property value
- Insurance eligibility
- Mortgage approval
- Future renovations
- Resale potential
- Ongoing maintenance costs
A property that looks perfect during an open home can contain significant hidden risks that only become visible when you know how to read the document.
1. Flood Risk and Natural Hazards
This is one of the most important sections in any LIM report.
Look for references to flooding, overland flow paths, stormwater issues, coastal inundation, river flooding, ponding, and surface water accumulation. Questions to ask include: has the property flooded before? Is it located within a flood hazard zone? Are there future climate-related flood risks?
Why it matters: Flood-prone properties may face higher insurance premiums, reduced buyer demand, lower resale values, and expensive mitigation requirements. Some lenders have become increasingly cautious about properties in identified flood zones — a trend that is only strengthening as climate risk assessment improves.
Critical point: Not all flood risk appears in the LIM. The LIM reflects only what the council has formally mapped. A property with a history of flooding may show no flag if the area hasn't been formally assessed.
2. Building Consents and Code Compliance Certificates
Every significant building project should have appropriate council approvals. Check for:
- Building consents
- Code Compliance Certificates (CCC)
- Certificates of Acceptance (CoA)
- Inspection records
Warning signs include missing CCCs, incomplete consents, outstanding inspections, and unresolved compliance issues.
Why it matters: A missing CCC doesn't automatically mean the work is non-compliant — but it does mean you can't confirm it is compliant. Banks and insurers may become cautious when compliance records are incomplete. That distinction matters at settlement and again when you try to sell.
Common trap: A house built in 1960 may have a CCC on file from 2003 for a kitchen renovation. Buyers often see the CCC and assume the house is compliant — but the 2003 CCC only covers the kitchen renovation. The original 1960 build may never have had formal compliance documentation.
3. Unconsented Building Work
One of the most common LIM surprises. Examples include decks, sleepouts, carports, garages, extensions, bathrooms, and retaining walls.
If improvements exist on the property but council records do not account for them, investigate further. Sometimes the discrepancy is innocent — older work predating consent requirements. Other times it indicates work completed without approval.
Why it matters: You may inherit responsibility for rectifying the issue. Depending on the council and the type of work, that could mean anything from obtaining a Certificate of Acceptance to demolishing and rebuilding the structure.
4. Land Stability Concerns
Look for references to subsidence, slippage, land movement, fill land, geotechnical concerns, and erosion. Some councils specifically identify unstable land areas within their district plan overlays.
Why it matters: Foundation repairs can cost tens of thousands of dollars and may be uninsurable. Fill land — common in subdivisions developed on former farmland, reclaimed land, or areas with stream diversions — carries particular risk in earthquake-prone areas due to liquefaction potential.
5. Easements and Encumbrances
Many buyers overlook easements. An easement grants someone else certain rights over part of the property — and those rights transfer with the title.
Common examples include drainage easements, sewer easements, access rights for neighbouring properties, and utility easements for power or telecommunications infrastructure.
Why it matters: You may be restricted from building over affected areas. The easement corridor might run directly through the section you were planning to extend into. Check easement positions early, not after you've already designed your renovation.
6. Stormwater and Wastewater Infrastructure
Check for public pipes crossing the property, drainage easements, stormwater channels, and sewer mains. The LIM should show whether the property connects to public infrastructure and whether any public pipes cross the section.
Why it matters: Future maintenance or building projects may be restricted. Some infrastructure corridors can significantly reduce development potential. Councils have right-of-access to public assets — meaning they can dig up your lawn to repair a pipe if needed.
7. Heritage Restrictions
Certain properties are protected under district plans. Look for heritage listings, character area protections, and heritage precincts.
Why it matters: You may require council approval before making changes — and in some cases, approval may not be granted at all. Heritage restrictions can make renovations significantly more expensive and complex, and may limit the type of work that is permitted even with council sign-off.
8. Future Road Designations
One of the most overlooked LIM risks. Councils may identify future road widening projects, transport corridors, and infrastructure designations that affect the property.
Why it matters: A road designation can affect future property value, development opportunities, and marketability. In some cases it can also trigger compulsory acquisition proceedings. This is particularly relevant near arterial routes in growing cities.
9. Planning Restrictions
Many buyers only discover planning limitations after settlement. Look for height restrictions, recession planes, protected trees, setback requirements, and design overlays.
Why it matters: Your planned renovation may not be permitted. A protected tree on the section may restrict earthworks. A recession plane requirement may prevent you from adding a second storey. Understanding what is and isn't possible before purchase is far cheaper than discovering the constraints after.
10. Contaminated Land Records
Look for references to HAIL sites (Hazardous Activities and Industries List), historic industrial activities, and contamination investigations. Properties on or near former orchards, petrol stations, dry cleaners, and industrial sites carry elevated contamination risk.
Why it matters: Contaminated land can require costly remediation and may affect lending decisions. In some cases it can also create ongoing liability for the landowner. Lenders and insurers increasingly scrutinise contamination history.
11. Outstanding Council Notices
Check whether the council has issued compliance notices, building notices, enforcement actions, or outstanding requirements. Section 124 notices under the Building Act, for example, require certain building work to be carried out — and do not expire with ownership change.
Why it matters: These obligations transfer with the property. You become responsible for resolving them after settlement — at your cost.
12. Insurance and Lending Risks
The most important question after reviewing a LIM is: will the issues identified affect my ability to insure or finance the property?
Pay particular attention to flood zones, geotechnical concerns, unconsented work, and structural issues. These are often the factors lenders and insurers focus on most heavily — and the ones that can derail a purchase late in the process.
The Biggest Red Flags in a LIM Report
If you see any of these, investigate further before proceeding:
- Flood history or flood hazard zone classification
- Unconsented building work
- Missing Code Compliance Certificates
- Land instability or fill land notation
- Active council complaints or enforcement actions
- Road designations or infrastructure corridors
- Heritage restrictions
- Contaminated land records
- Public infrastructure crossing the property
These don't automatically mean you shouldn't buy. They mean you need more information — and that more information should be gathered before you go unconditional.
Questions Every Buyer Should Ask
After reviewing a LIM report, work through these:
- Are all improvements consented and covered by CCCs?
- Are there any unresolved council notices or enforcement actions?
- Is the property exposed to natural hazards — particularly flood or land instability?
- Will future development or renovation be restricted by planning rules or easements?
- Could insurance become difficult or expensive based on what the LIM reveals?
- Are there hidden maintenance obligations I'll inherit?
- Will any of these issues affect resale value or buyer pool when I eventually sell?
How LIMiQ Helps You Analyse a LIM Report
Traditional LIM reports can be overwhelming. Many exceed 100 pages and contain highly technical language — consent histories, district plan cross-references, technical hazard notation, legal descriptions of easements.
LIMiQ processes the entire LIM through a three-stage AI pipeline: classifying sections, cross-referencing with spatial data, and applying a deterministic rule engine that flags legally and financially significant issues. It automatically surfaces:
- High-risk findings across all five risk categories
- Natural hazard disclosures and their implications
- Compliance gaps and missing CCCs
- Planning restrictions affecting future use
- Easements and infrastructure constraints
- Hidden council disclosures that are easy to miss in a long document
Instead of spending hours reading council documents, buyers can quickly understand the key issues that may affect their decision — in minutes, not days.
Frequently Asked Questions
What is the most important thing to check on a LIM report?
Flood risk, building consent records, and unconsented work are generally among the most important items. In practice, the relative importance depends on the property — an older character home in an elevated suburb has different risk priorities than a newer townhouse in a low-lying coastal area.
Does a LIM report show unconsented work?
Sometimes — but not always. The council records consents they issued. Work done without consent doesn't automatically appear. A LIM may hint at unconsented additions through consent gaps or through property records that don't match what's on site, but a building inspection is the more reliable way to identify physical non-compliance.
Can a bank reject a mortgage because of a LIM report?
Potentially. Significant natural hazards, compliance issues, or insurance concerns identified in a LIM can influence a lender's valuation assessment or lending conditions. Some lenders require specific engineering reports or insurance confirmation before approving finance on properties with flagged issues.
Can I buy a house without reading the LIM report?
You can — but it significantly increases your risk. Undisclosed issues don't disappear after settlement. They become your financial responsibility. The LIM is one of the few documents that tells you what the council knows before you take ownership.
Is a LIM report enough on its own?
No. It should be reviewed alongside the title documents (certificate of title, property file), a physical building inspection report, independent legal advice, and insurance assessments. A LIM tells you what the council knows — it doesn't replace specialist inspection or legal review.
Final Thoughts
A LIM report is one of the most powerful due diligence tools available to New Zealand home buyers. The key is knowing what to look for.
A few hours spent understanding flood risks, compliance records, planning restrictions, and infrastructure issues could save you thousands of dollars and years of stress.
Before you go unconditional, make sure you understand the story your LIM report is telling. Because what you don't know today could become a very expensive problem tomorrow.
