Building Inspection Time: Common Issues and How Banks and Insurers View Them (Part 1)

Now is a great time for first-home buyers in NZ to enter the property market and take advantage of current opportunities. Before committing to a purchase, we strongly advise obtaining an independent builder’s report to gain a clear understanding of the property’s condition.

If you’re considering an older home or a property from a specific era, be aware that certain issues uncovered in a builder’s report may affect your ability to secure insurance and, by extension, your mortgage approval.

In this two-part series, Velocity Financial Adviser Manisha Raman and Caveo General Insurance Adviser Alice Kauri share their insights on how common findings in building inspections can impact both your lending options and insurance choices. Their practical guidance will help you make well-informed decisions throughout your home-buying journey.

We’ll begin with insurance tips from Alice Kauri at Caveo, followed by advice from Manisha Raman in November on how these findings can influence a bank’s decision to lend on your chosen property.

Insurance Challenges: What Building Reports Reveal and Why Insurers Care

By Alice Kauri

In the property approval/ticking-off conditions process, our team at Caveo help our clients determine whether their home can obtain ‘full insurance with no noted exclusions’ (per the bank’s instructions). In plain English, this means making sure the home can be insured for everything, with no special conditions or restrictions, so the insurance company isn’t excluding any important issues like leaks, structural problems, or other risks. This is important because banks usually require full insurance before approving a mortgage, to protect both you and them if anything goes wrong with the property.

Key Criteria for Home Insurance Approval

To make sure a property qualifies for full insurance coverage with no exclusions, we need to see that it ticks several important boxes. The home should be structurally sound, watertight, have no outstanding EQC claims, feature modern TPS wiring, and generally be in well-maintained condition. The best and simplest way to confirm these requirements is by reviewing a thorough builder’s report.

Below I’ll explain the issues we see related to the above and the ‘key words’ to look out for in a builder’s report.

Elevated Moisture Readings – commonly found around showers and windowsills.


Insurance Risk: Elevated moisture readings are often classed as gradual damage, which is considered a ‘general exclusion’.
Impact: Damage from leaks may be covered under the ‘hidden gradual damage’ benefit, but it’s not guaranteed that it will meet the criteria. The hidden gradual damage benefit is sub-limited to between $3k and $5k depending on the insurer, which is not high enough for the damage that can occur.
Interesting personal story! We just purchased our first home, which we planned to renovate anyway, but there were elevated moisture readings under a windowsill in the bedroom. After investigating while prepping the home for renovations, we found that the framing in the wall below the windowsill was rotting badly and needed replacing! This would definitely have caused issues if not investigated and remediated.

Roof Damage & Blocked Gutters – common findings include loose or rusting nails and poor house maintenance.


Insurance Risk: Rust is classed as gradual damage, which, as mentioned above, is not covered. There would be no way around this as it is not hidden and would be attributed to ‘poor maintenance’. The same applies to any leaks caused by blocked gutters.
Impact: Sudden storm damage may be covered, but rust or poor maintenance is not. Additionally, if an assessor finds the storm damage could have been prevented by regular maintenance checks, then the claim would be declined.

Structural Issues – commonly seen as cracks in the ring foundation, rotting piles, sinking piles, and piles not secured.


Insurance Risk: Again, gradual damage, and will not be classed as hidden (in most cases).
Impact: The worst-case scenario would be that your house collapses (if you’re in Wellington and we have an earthquake, and your home isn’t structurally sound, then it’s not too far-fetched!). Again, if the collapse of your home could have been prevented with maintenance checks, this would suddenly turn into a very complex claim for everyone involved (because if your home was a crumbled pile of debris, we wouldn’t just leave it to be declined!).

Old Wiring, Scrim and Dux Quest – common in pre-1945 builds.


Believe it or not, Dux Quest is not as much of an issue for some insurers now if it has been, so far, unproblematic. Scrim and old wiring, however, are a big fire hazard.


Insurance Risk: This could be something that we would see as a ‘noted exclusion’ on the policy wording, and the bank would then decline lending. Best-case scenario in this situation would be that you have an ‘additional excess’ applied to your policy, but these can be up to $10,000 excess for any claims related to the above.
Impact: Both scrim and old wiring create a fire hazard in your home. Old wiring often has rubber insulation which deteriorates and leaves exposed wires. These aren’t overly common nowadays, but Dux Quest is still cited often. Dux Quest often leaks and creates larger problems.

Borer

Insurance Risk: Pest damage is generally excluded.
Impact: Homeowners must manage treatment and repairs themselves. Leaving the borer untreated could result in damage to the foundations of your home.

Poorly Maintained Home

Insurance Risk: Cosmetic defects and poor workmanship are not covered. Additionally, if a home is poorly maintained, this can cause gradual damage over time.
Impact: No insurance payout unless they cause hidden gradual damage.

In Summary


If you come across these findings in a builder’s report from an insurance point of view, it’s important to share what you plan to do next to sort things out. From what I’ve seen, getting lending approval isn’t always straightforward. That’s why I’m passing this over to Manisha—she’ll walk you through what you need to do to get the bank’s “okay”.
