LIM Reports, Builders Reports, and Valuations: What the Bank Actually Requires
A quick heads-up before we dive in: This article is strictly for general informational purposes and does not constitute financial, legal, or tax advice. Every situation is entirely unique, and bank lending policies change frequently. Before making any decisions about your property journey, it is highly recommended that you seek independent advice from a qualified financial adviser.
When you walk through an open home, you are likely looking at the natural light, the size of the bedrooms, and whether the kitchen island is big enough for entertaining.
When a bank looks at that exact same house, they are looking at one primary thing: Risk.
They want to feel confident that the asset they are lending against is secure, legally compliant, and actually worth the price tag. To mitigate that risk, banks often rely on three major pillars of due diligence: LIM Reports, Builders Reports, and Registered Valuations.
Here is a closer look at what the bank is typically looking for in each document, and when they might become a mandatory condition for your mortgage approval.
1. The LIM Report & The Insurance Chain Reaction
A Land Information Memorandum (LIM) is a comprehensive history of the land and property held by the local council. While banks themselves do not usually require to see a copy of the LIM for a standard purchase, the LIM can often be the ultimate gatekeeper for your home insurance.
Banks generally have a firm rule: if you cannot insure the property, they will not provide the mortgage. Furthermore, they typically require a Certificate of Currency showing standard insurance cover without special conditions or major exclusions.
If a LIM report flags that the property sits in a severe flood zone, a coastal erosion area, or has significant unconsented works, you are usually obligated to disclose this to your insurer. If the insurer adds an exclusion to your policy (e.g., "We will cover the house, except for flood damage"), the bank may pause or even decline your finance. Ultimately, it often isn't the LIM that stops the bank directly; the LIM can affect the insurance, which in turn affects the bank and your lending.
2. Builder's Reports: When Are They Requested?
A standard builder's report is a visual inspection of the home's overall condition, and a bank will often make a clean, written report from an accredited inspector mandatory in a few specific scenarios:
It is a condition on your Sale & Purchase Agreement: If you tell the bank you want to check the building's condition as a finance condition, they will usually adopt that condition as their own. Simply put: if you feel you need to know, the bank wants to know too.
The Registered Valuer flags Deferred Maintenance: If the bank orders a valuation and the valuer notices sagging floors, a compromised roof line, or visible issues that a layman could spot, they will likely flag "deferred maintenance" in their report. The bank will then often require a professional building inspection to investigate further.
The Listing flags a warning: If the property is actively marketed with phrases like "The Handyman’s Dream,""Renovator’s Delight," or "Bring your toolbelt," the bank's assessors may flag the property as needing significant work and request a builder's report before approving the security.

3. Registered Valuations & Internal System Triggers
A registered valuation is an extensive, independent assessment of a property's current market value, conducted by a registered valuer.
Banks generally require one in scenarios like
Purchasing with less than 20% deposit
Buying privately without an agent
Purchasing a property from a family member
Buying a brand new build property
However, there is another common trigger that surprises many buyers. Even if you have a full 20% deposit, you might still be asked for a registered valuation if the bank's internal pricing system gets confused.
Banks use internal, automated desktop systems to estimate what they think a property is worth. If the purchase price you have agreed upon is significantly higher (or significantly lower) than what their internal system was expecting, it can trigger an alert. This doesn't happen with every bank or every property, but when it does occur, the bank will typically ask for a full registered valuation so a human can manually confirm the property's true market value.

Note on Valuations: The Strict Ordering Rule
If a valuation is required, you cannot simply hire a valuer yourself. New Zealand banks require all valuations to be ordered blindly through an approved, centralised system (such as Valocity or CoreLogic). This system randomly assigns an independent valuer to your property, ensuring the report is completely unbiased.
Secure Your Pre-Approval Before You Start Paying for Reports
Paying for a LIM, a builder's report, and a registered valuation can quickly become an expensive exercise. You should generally avoid spending that money until you have clarity around your borrowing power and understand what the bank will actually require.

We will guide you on what reports the bank may require for your specific scenario, order your valuations through the correct approved channels, and help you negotiate the smoothest path to your new home.

Understanding Bank Requirements
How does a LIM report affect a mortgage application?
While a bank may not directly ask for a LIM report on a standard purchase, the LIM can highlight risks like flood zones or unconsented works. You must disclose these risks to your insurance company. If the insurer places special exclusions on your policy as a result, the bank may decline your mortgage, as they typically require standard, unconditional insurance cover.
When do NZ banks require a building report?
Banks will often require a building report if you have included it as a condition on your Sale & Purchase agreement, if the property is advertised as a "do-up" or "renovator's dream," or if a registered valuer flags visible deferred maintenance that needs further investigation.
Why do banks ask for a registered valuation if I have a 20% deposit?
Even with a 20% deposit, a bank may ask for a registered valuation if their internal automated systems flag the purchase price as being significantly higher or lower than their expected data suggests. They may also require one if you are buying privately or purchasing from a family member.
Can I order my own registered valuation for the bank?
No. If a bank requires a registered valuation for a mortgage approval, you cannot hire a valuer directly. The valuation must be ordered through an approved, independent, centralised system (such as Valocity or CoreLogic), which assigns a valuer randomly to ensure complete neutrality.
