Title: What Is a Builders Report — and Do You Need One When Buying in Christchurch?

A builders report is a non-negotiable part of buying property in Christchurch. Not because it's legally required — it isn't — but because the alternative is buying one of the largest assets of your life without knowing if it has serious defects.

In a city with the earthquake history Christchurch has, that's a genuinely risky decision.

Here's what you need to know.

What Is a Builders Report?

A building report is a detailed visual inspection of a property conducted by a qualified building inspector. The inspector will assess the condition of the property, including its structure, plumbing, electrical systems and any other potential issues. Govett Quilliam

The report gives you a clear picture of the property's current condition — what's working, what needs attention, what needs urgent repair, and roughly what any remediation might cost.

The report helps identify any current and potential issues with the property. You can also request the inspector to provide you with an idea of the costs associated with any necessary repairs or maintenance. Govett Quilliam

It is a visual inspection only. Any problems concealed behind finished surfaces won't be included in the report. Govett Quilliam A building inspector cannot see inside walls, under floors, or above ceilings — they can only assess what's visible. This is why a clean report is reassuring but not a complete guarantee.

What Does a Builders Report Cover?

A standard builders report in New Zealand typically covers:

• Structure — foundations, framing, load-bearing walls
• Roof — condition of roofing material, flashings, gutters and downpipes
• Exterior — cladding, weathertightness, windows and doors
• Interior — walls, ceilings, floors, stairs
• Plumbing — visible pipework, hot water system, drainage
• Electrical — visible wiring, switchboard condition (note: electrical inspectors are separate specialists)
• Moisture — signs of water ingress, dampness, or mould
• Subfloor — where accessible, condition of piles and underfloor structure
• Decks, outbuildings, fences — condition of external structures

More detailed reports may include thermal imaging or invasive moisture testing — useful for properties with cladding types known for weathertightness issues.

Why It Matters Extra in Christchurch

Christchurch buyers face specific risks that make a building inspection more important than in most other NZ cities.

Earthquake damage: The 2010 and 2011 earthquakes caused significant structural damage across many properties. Some was repaired properly. Some was patched cosmetically. Some was never fully addressed. A qualified building inspector knows what to look for — foundation cracking patterns, chimney issues, frame distortion, and drainage changes caused by land movement.

Post-quake repair quality: Even where repairs were done, the quality varies enormously. Work carried out under EQC or private insurance was done by a range of contractors under significant time pressure. A building inspector can identify where repairs may not meet current standards.

Unconsented work: Christchurch has a higher than average rate of alterations done without building consent — partly a legacy of post-earthquake repairs done informally. Your building inspector may identify work that doesn't appear in council records, which you can then cross-reference against the LIM.

Cladding issues: Some Christchurch properties built in the 1990s and early 2000s have monolithic cladding types — plaster or fibre cement — that are associated with weathertightness problems. These require careful inspection, and sometimes specialist weathertightness assessment beyond a standard report.

How Much Does a Builders Report Cost in Christchurch?

Across New Zealand, a typical builder's report costs anywhere between $400 and $1,000, although prices can fluctuate outside this range depending on specific circumstances. This estimate generally applies to standard, non-invasive inspections for average-sized homes. Builder Connect NZ

In Christchurch, expect to pay:

• Standard residential report: $450–$700
• Larger or more complex properties: $700–$1,000+
• Reports including thermal imaging or moisture testing: $700–$1,200+

The cost is almost always worth it. On a $700,000 purchase, a $500 building report that identifies $30,000 of remediation work — or gives you grounds to negotiate the price down — pays for itself many times over.

Is It Legally Required?

No — obtaining a building report is not a requirement when buying a house, but it is highly recommended, even for a newly built home. Govett Quilliam

The way to protect yourself is to include a building report condition in your offer. This gives you a set number of working days to commission the report and, if the findings are unsatisfactory, the ability to renegotiate or cancel the contract.

Can You Use the Vendor's Report?

Sometimes sellers commission their own building report as part of the marketing package. It may look helpful, but treat it with caution.

While it can be tempting to rely on a report provided by the vendor or their agent, you can only legally rely on the report you have obtained. If you accept the vendor's report and find a problem later, you may have limited options for recourse. Govett Quilliam

Always get your own report, commissioned independently by you. It should be addressed to you — not the vendor — to ensure the inspector's legal duty of care runs to you as the buyer.

How to Choose a Building Inspector

If you want true peace of mind, it pays to employ a qualified building inspector that carries out their work in accordance with the New Zealand Property Inspection Standard. You should always opt for an inspector who has professional indemnity insurance. This means that if an issue arises with the home after you've bought it that should have been identified in the report, you can potentially claim compensation. Canstar

The professional you use should be a member of an organisation such as the NZ Institute of Building Inspectors, the NZ Institute of Building Surveyors, or the Institution of Professional Engineers New Zealand. Canstar

Ask specifically:

• Are you a member of a recognised industry body?
• Do you carry professional indemnity insurance?
• Have you inspected properties in Christchurch extensively — and are you familiar with earthquake-related building issues?
• Will you walk me through the report findings in person or by phone?

The last point matters. A good building inspector will explain the findings to you directly, not just email a PDF and move on.

Practical Steps

1. Include a building report condition in your offer — allow at least 5–7 working days
2. Commission your own inspector — don't rely on the vendor's report
3. Choose an inspector with professional indemnity insurance and relevant experience
4. Attend the inspection if possible — you'll learn far more than just reading the report
5. Ask the inspector to talk you through the findings and give you an estimate of any remediation costs
6. Review the report with your solicitor — they can advise on your options if issues are found
