A concerning trend of building defects and inspection failures is emerging across New Zealand, with experts warning of potential systemic issues that could affect property buyers for years to come.
A troubling pattern is emerging in New Zealand’s construction industry. Building inspectors are warning of a new crisis in the making, with failure rates reaching alarming levels and quality concerns mounting across the country. For property buyers, understanding these risks has never been more crucial.
The statistics are stark and deeply concerning. More than three decades after the initial leaky building crisis, over a third of residential new builds in greater Auckland failed their final inspection in the year to May 1, 2025. The failure rates break down across various critical areas: cavity wrap issues affecting 25.6% of properties, cladding problems in 22.1%, framing defects in 27%, foundation issues in 15.2%, and drainage problems in 14.5%.
Jeff Fahrensohn, Auckland Council’s chief building inspector, has been documenting these issues through social media, showing examples of deliberate concealment of defective work. In one notable case, he discovered tape placed to “hide things that are not right with the framing. That’s just blatant concealment.”
These aren’t isolated incidents. Building inspection services across New Zealand face significant resource constraints as high failure rates require multiple re-inspections of the same properties. John Gray, President of the Homeowners and Buyers Association of New Zealand, reports involvement in cases where new houses failed 22 inspections, yet potential buyers were still considering purchase.
The New Zealand Government’s fast-track housing initiatives have created unprecedented pressure on the building inspection process. Minister Chris Penk’s reforms aim to streamline building consent processes, but industry experts warn this approach compromises essential quality controls.
Gray emphasises the fundamental challenge: “the crux of the matter in relation to speeding building up is not to reduce red tape. It’s to maintain it and actually have consequences for that sort of conduct.”
The pressure to build quickly is creating conditions where building inspectors report that fast-track consenting creates environments where quality control becomes secondary to speed. In late May 2025, the first private building consent authority, Building Consent Approvals (BCA), was launched, with its director stating that BCA would focus on low-risk residential bulk house builders, with building consents issued within 10 working days and 30% of inspections undertaken remotely.
A recent High Court case has highlighted serious concerns about New Zealand’s unregulated pre-purchase building inspection sector. Justice Peter Andrew criticised the sector’s “poor quality” reports after awarding $500,000 in damages to a first-home buyer who purchased a rotting, leaky house.
The case involved three separate pre-purchase reports conducted on the same Onehunga property. Though the house had serious weathertightness problems, two of the reports cleared the property, while just one identified moisture issues and recommended further investigation.
The judgment revealed fundamental problems with the industry structure. As building law expert Matthew Ball noted in his expert evidence, “Formal qualifications, membership of a professional institution or indemnity insurance are not mandatory requirements and therefore anyone who is so-minded can set themselves up as a pre-purchase inspector and produce reports.”
While a New Zealand Standard for residential property inspections exists, “adherence to this standard is not mandatory”. Pre-purchase reports are also “entirely visual” and subject to “significant limitations”, with inspectors “predominantly reliant upon their personal knowledge and experience.”
The building inspection industry is responding to these challenges, though gaps remain. Professional organisations like the New Zealand Institute of Building Surveyors (NZIBS), Building Officials Institute of New Zealand (BOINZ), and New Zealand Institute of Building Inspectors (NZIBI) provide accreditation processes, but membership isn’t mandatory.
Leading inspection companies are raising standards independently. Red LBP, one of New Zealand’s larger inspection services, emphasises the importance of using Licensed Building Practitioners (LBPs) for inspections, noting that “building inspectors in New Zealand aren’t regulated” and “there’s no requirement for them to have any formal building qualifications or even a lick of experience in construction.”
The company reports having “the largest reach of any building inspection service in New Zealand” and emphasises professional indemnity insurance coverage, noting that “less than half of the inspectors in New Zealand carry it.”
For buyers navigating today’s market, these quality issues create both risks and responsibilities. The current building quality crisis represents a critical challenge where sacrificing Building Code compliance risks repeating the catastrophic leaky building crisis of the past.
Consumer Protection guidance recommends several key steps for buyers:
Choose qualified inspectors carefully. Look for registered building surveyors through the New Zealand Institute of Building Surveyors or qualified professionals from BOINZ or NZIBI. Verify they can perform NZS 4306 pre-purchase inspections and carry professional indemnity insurance.
Don’t rely on vendor-supplied reports. Some sellers include building reports with property documents, but buyers should commission their own independent inspections. As Consumer Protection notes, “You’re unlikely to have any come back if the report misses anything” when relying on vendor reports, “because the vendor is the client — not you.”
Understand inspection limitations. The standard pre-purchase inspection is visual only, meaning “it won’t identify any problems concealed behind finished surfaces, eg plumbing, framing, insulation or wiring.” Additional specialist inspections may be necessary based on initial findings.
Different property ages present different risk profiles. The settled.govt.nz Property Checker tool helps buyers identify potential issues based on the construction era and materials. Key risk areas include:
Older properties may have issues with unbraced chimneys made from brick or concrete (typically pre-1970s construction), heavier roof tiles not properly fixed to framing, and potential borer problems in timber construction.
Modern builds face different challenges, as evidenced by the high failure rates in new construction. Issues frequently involve structural steel weld failures, non-compliant framing, improper plumbing installations, and deliberate concealment of substandard work.
The financial implications of building defects can be devastating. The recent Onehunga case resulted in $500,000 in damages, while other documented cases involve multimillion-dollar repair bills for apartment complexes. Gray notes that defective buildings have “long tentacles” affecting owners “financially and emotionally.”
One couple involved in a defective apartment building told OneRoof their complex required extensive structural repairs, with initial issues dismissed as “teething problems” of new construction that “kept coming” and eventually revealed serious structural unsoundness.
The situation is particularly concerning for new builds, where buyers might reasonably expect compliance with current Building Code standards. However, building inspections have become more critical than ever, with trade-qualified building inspectors most commonly identifying structural steel weld failures, non-compliant framing, improper plumbing installations, and deliberate concealment of substandard construction work.
For buyers considering design and build homes, understanding quality control processes and engaging independent professional inspections throughout construction becomes essential protection.
These quality issues have broader implications for property investment decisions. Buyers considering REITs as an investment option should understand how building quality issues might affect individual property values and portfolio performance over time.
The current crisis highlights why professional building inspection services aren’t an optional luxury—they’re essential protection against documented construction quality decline across Auckland and New Zealand.
Industry experts emphasise the importance of maintaining rigorous building inspections during periods of rapid construction growth. Some call for more radical reform, looking to international examples like Canada, which implemented comprehensive licensing requirements following its own building crisis.
Gray advocates for “significant consequences for builders who get it wrong or who are negligent,” noting that in Canada, “They make everyone licensed, so if you’re a development company, you are licensed… if they build something that fails, then those people lose their licence.”
Professional building inspection services provide essential protection for consumers during this quality crisis. Trade-qualified building inspectors offer independent verification of construction quality and Building Code compliance, ensuring New Zealand’s rush to build more homes doesn’t sacrifice building them properly.
The current building quality crisis in New Zealand presents serious challenges requiring informed decision-making from property buyers. While the housing market shows positive signs of recovery, understanding construction quality risks and engaging qualified professionals for building inspections has never been more important.
For homeowners, property buyers, and investors, the message is clear: professional building inspection services aren’t optional—they’re essential protection against a documented decline in construction quality. As New Zealand addresses these challenges, independent building inspections provide crucial oversight needed to protect individual investments and maintain building standards.
The key to navigating this environment successfully lies in choosing qualified, insured professionals who understand current Building Code requirements and can identify both obvious and concealed defects. In an environment where one-third of new builds fail council inspections, this professional oversight becomes the buyer’s primary protection against costly building defects that could affect property value and safety for years to come.
