Yes, a quantity surveyor (QS) can be a real asset when you're dealing with an insurance claim after storm damage. They bring independent, professional cost expertise to the table — helping ensure your insurer's settlement offer actually covers the full cost of putting your home back to the way it was. In New Zealand, where storms, flooding, and high winds can cause significant structural and weathertightness damage, having a QS in your corner can make a meaningful difference to your claim outcome.
What Does a Quantity Surveyor Actually Do?
A quantity surveyor is a construction cost specialist. Their core skill is measuring, pricing, and managing the costs of building work — from small repairs right through to large construction projects. In the context of an insurance claim, a QS can:
- Assess the full scope of damage to your property, including hidden or consequential damage that's easy to overlook
- Prepare a detailed Schedule of Quantities — a line-by-line breakdown of every repair item, material, and labour cost
- Provide an independent cost estimate that reflects current New Zealand market rates for materials and trades
- Review and challenge your insurer's assessment if you believe it undervalues the repair work needed
- Liaise with builders, engineers, and loss adjusters on your behalf
- Track costs during the repair process to ensure the work stays on budget and within the agreed scope
Why Is Independent Cost Assessment So Important?
Insurance companies typically appoint their own loss adjuster to assess storm damage and estimate repair costs. While loss adjusters are professionals, their role is to represent the insurer's interests. A QS you engage independently works for you — giving you an expert second opinion on whether the settlement offer is fair and complete.
This matters because storm damage can be deceptive. Wind-driven rain, for example, can penetrate wall cavities and cause damage that isn't immediately visible. Roof damage may affect insulation, ceiling linings, and electrical fittings. A thorough QS assessment helps ensure nothing is missed before you agree to a settlement.

What Types of Storm Damage Can a QS Help With?
A QS can assist with cost assessments across a wide range of storm-related damage, including:
- Roof damage — missing or broken tiles, damaged metal roofing, compromised flashings
- Structural damage — wind damage to framing, posts, or decks
- Weathertightness failures — water ingress through walls, windows, or rooflines (relevant to NZ Building Code clause E2 External Moisture)
- Flooding and drainage damage — floor coverings, subfloor framing, drainage systems
- Cladding damage — cracked or displaced weatherboards, fibre cement, or plaster systems
- Interior damage — damaged GIB plasterboard linings, insulation, cabinetry, and fittings

How the Process Typically Works
Here's a general overview of how a QS can support your insurance claim:
| Step | What Happens |
|---|---|
| 1. Initial inspection | QS visits your property to assess and document all damage |
| 2. Scope of works | QS prepares a detailed list of all required repairs |
| 3. Cost estimate | QS prices the repairs at current NZ market rates |
| 4. Review insurer's offer | QS compares your estimate against the insurer's assessment |
| 5. Negotiation | QS provides evidence to support a revised settlement if needed |
| 6. Construction monitoring | QS can oversee repairs to ensure quality and cost control |
NZ Building Code and Repair Standards
It's important to note that any repair work must comply with the NZ Building Code and relevant New Zealand Standards. Depending on the extent of the damage, a building consent may be required — always check with your local council before work begins. MBIE Building Performance has clear guidance on when consents are needed and what qualifies as exempt work under Schedule 1 of the Building Act.
For structural repairs, work may need to be carried out or supervised by a Licensed Building Practitioner (LBP). You can verify a tradesperson's licence at Licensed Building Practitioners.
When to Call a Professional
You should strongly consider engaging a quantity surveyor if:
- Your insurer's settlement offer seems lower than expected
- The damage is extensive or involves structural elements
- You're unsure whether all damage has been identified and included in the claim
- The repair process is complex and involves multiple trades
- You want independent oversight of the repair budget and contractor invoices
A QS is particularly valuable when dealing with large or complicated claims where the difference between a fair and an inadequate settlement could run into tens of thousands of dollars.
If your storm damage involves electrical systems, any repair or reinstatement work must be carried out by a registered electrician — this is restricted work under NZ law. Check EWRB for registered electricians. Similarly, any plumbing or drainage repairs must be done by a licensed plumber or drainlayer — see PGDB for details.
