A professional building assessment can protect you from financial disaster—or leave you exposed to devastating losses if mishandled.
Whether you’re purchasing your first apartment in Wellington or investing in property across Auckland, Christchurch, or Hamilton, understanding the critical errors to avoid during building inspections is essential. Morgan Kircher, Managing Director of Alert Building Inspections with over 25 years’ experience, has witnessed countless purchasers make avoidable mistakes that continue to impact them years after settlement.
Some purchasers become emotionally attached to a property and submit offers without securing a professional evaluation. This gamble consistently produces adverse outcomes.
Industry research from Master Builders indicates that approximately 80% of New Zealand residential properties contain at least one defect requiring remediation. That immaculate-looking home might conceal moisture penetration behind recently refreshed paintwork. A thorough property inspection checklist identifies these issues before you’re contractually obligated, giving you leverage for negotiation or withdrawal.
What does avoiding this step cost? One Auckland family uncovered $48,000 in weathertightness remediation four months post-settlement—damage that would have been identified during proper assessment.
Building inspectors vary dramatically in expertise and value. Selecting the lowest-priced option frequently becomes your costliest decision.
A qualified inspector should possess relevant certifications, maintain current professional indemnity insurance, and demonstrate regional knowledge. New Zealand’s diverse geography—from Auckland’s volcanic terrain to Canterbury’s liquefaction-prone soils—creates location-specific foundation and drainage challenges requiring experienced assessment.
Morgan Kircher stresses that seasoned professionals identify defects that recently qualified inspectors routinely miss. Does your chosen inspector understand how your region’s geological characteristics influence building performance?
Many purchasers treat building assessments as administrative requirements and don’t attend in person.
This represents a significant wasted opportunity. Your presence enables direct questioning, understanding maintenance obligations, and observing problems firsthand. Your inspector can clarify distinctions between aesthetic concerns and structural deficiencies, facilitating informed decisions about repairs and future modifications.
Accompanying your inspector also builds essential knowledge about the property’s systems—critical information for ongoing maintenance.
Standard building inspections cover visual examination of accessible areas, but specific issues demand specialist expertise.
When your inspector suggests methamphetamine testing, take it seriously. Data from the New Zealand Drug Foundation demonstrates that decontamination costs for affected properties frequently exceed $100,000. Similarly, if asbestos or electrical issues arise during the visual assessment, commission specialist evaluations to verify compliance and address safety concerns beyond the scope of the standard inspection.
For commercial properties, ensure you arrange appropriate commercial assessments that address business-specific requirements and compliance obligations.
These supplementary tests increase upfront expenditure but prevent catastrophic financial consequences later.
Receiving inspection documentation and merely reviewing the executive summary occur surprisingly frequently.
Every section provides valuable intelligence about the property’s condition, maintenance requirements, and projected future expenses. Comprehending the distinction between immediate repairs and routine upkeep helps you budget accurately and prioritise post-purchase work.
Focus particularly on observations regarding moisture intrusion, structural movement, and items flagged for specialist review. These typically indicate the most substantial risks.

Recent construction doesn’t guarantee quality. Defects in new builds are alarmingly common.
The Ministry of Business, Innovation and Employment estimates that leaky building remediation has cost New Zealand taxpayers and property owners over $11.5 billion. Even newly completed homes can harbour workmanship deficiencies, material failures, or design flaws. A pre-settlement inspection of new construction identifies problems that remain the builder’s contractual responsibility to rectify.
Don’t surrender your inspection rights simply because the property appears pristine.
Building inspections examine the physical condition, but council records reveal the property’s consent and compliance history.
Unauthorised modifications, outstanding notices, or unresolved consent conditions transfer to you as legal obligations post-purchase. Cross-reference your building assessment with council documentation to verify that all alterations received proper consent and sign-off.
Properties nationwide, particularly older homes that have undergone renovation, may harbour compliance issues invisible during physical inspection.
Sellers occasionally provide their own inspection documentation. While potentially informative, these never substitute for your independent assessment.
Vendor reports may be outdated, potentially selective, or emphasise areas that don’t align with your concerns. Commission your own independent inspection to secure current, impartial information about the property’s actual condition.
Your inspector represents your interests exclusively, not the seller’s objectives.
Hurrying the inspection process or excluding appropriate conditions from your purchase agreement restricts your options.
Allow sufficient time for both primary inspection and any subsequent specialist assessments. Your sale and purchase agreement must include conditions granting withdrawal or renegotiation rights based on inspection discoveries. Discuss realistic schedules with your inspector and solicitor before submitting offers.
Properties in competitive markets can create pressure to make rapid decisions, but protecting your investment requires proper due diligence.
Learning from others’ errors costs substantially less than experiencing them personally. A comprehensive building inspection, conducted by qualified professionals, attended to personally, and acted upon appropriately, represents one of the most valuable investments in your property acquisition journey.
Morgan Kircher’s 25 years in the industry demonstrate that purchasers who avoid these critical errors consistently make superior buying decisions, negotiate more effectively, and enjoy substantially greater confidence in their property investments.
