The price looks right, and the neighbourhood ticks every box. But there’s one question worth asking before you sign anything — could this property contain asbestos?
If the home was built before 1990, the answer is almost certainly yes. That’s not necessarily a dealbreaker — it just means going in with your eyes open.
Asbestos was widely used in New Zealand building materials from the 1940s through to the mid-1980s. While the industry largely stopped using it by the late 1980s, a full import ban didn’t arrive until 2016. Thousands of Auckland homes built during this period are likely to contain asbestos-containing materials (ACMs) somewhere in their structure.
According to WorkSafe, around 220 New Zealanders die each year from asbestos-related diseases. Those numbers reflect past exposure, but they underline why identifying ACMs matters before committing to a purchase.
Exterior cladding and roofing. Fibrolite (asbestos-cement sheet) was one of the most popular cladding materials in mid-century construction. You’ll find it across suburbs like Pt Chevalier, Mt Eden, and Sandringham — anywhere post-war housing stock is common.
Textured ceilings and walls. Those swirled “popcorn” ceilings fashionable through the 1960s and 1970s often contain chrysotile asbestos. If a home still has original textured coatings, they deserve closer attention.
Vinyl flooring and backing. Older lino and vinyl tiles — particularly the geometric patterns popular in the 1970s — frequently used asbestos in the backing material and adhesives.
Pipe lagging and switchboards. Fibrous wrapping around pipes and hot water cylinders is common in subfloor areas. The brittle backing boards inside older fuse boxes can also be made from asbestos — an easy-to-miss detail that a thorough inspection can flag.
Here’s the part that often gets lost. Asbestos that’s intact and undisturbed is generally considered low risk. The danger comes when ACMs are damaged, deteriorating, or disturbed during renovation — cutting, drilling, or sanding materials that release microscopic fibres into the air.
Those fibres can lodge in the lungs and cause serious conditions, including mesothelioma and lung cancer. The effects can take decades to appear. The critical point for buyers: if you’re planning renovations on a pre-1990s Auckland home, you need to know what’s there before any work begins.
A building inspection conducted in accordance with NZS 4306:2005 will assess visible building elements and note materials that may contain asbestos. Drawing on our team’s century-and-a-half of combined expertise at Alert Building Inspections, our inspectors know where ACMs commonly appear in Auckland’s housing stock.
During an inspection, we may identify materials that warrant further investigation by a specialist asbestos surveyor. If we spot textured coatings, old cladding, or suspect flooring, we’ll flag them in your report and recommend next steps — typically professional testing by a licensed assessor.
Only laboratory analysis can confirm whether a material contains asbestos. You cannot tell by sight alone. Led by Morgan Kircher, who has spent more than 20 years in the building industry, our team emphasises thorough inspections on older Auckland properties.
Auckland’s building boom from the 1940s through the 1970s means certain areas have higher concentrations of homes likely to contain ACMs. Avondale, New Lynn, Onehunga, and Penrose all saw significant development during this period.
North Shore suburbs, including Birkenhead and Glenfield, also have substantial mid-century stock. South Auckland — Mangere, Otara, Papatoetoe — was largely developed in the 1950s and 1960s when asbestos use was at its peak in New Zealand.
Auckland’s coastal humidity and salt air can also accelerate the deterioration of asbestos-cement products over time, making older ACMs in exposed locations more likely to become friable and therefore more hazardous.
Finding asbestos shouldn’t automatically send you running. If ACMs are in good condition and you’re not planning to disturb them, management in place is often reasonable. If removal is needed, it must be carried out by a licensed removalist — and that cost should factor into your purchase negotiations.
The practical approach is straightforward. Get a professional pre-purchase inspection that considers the property’s age and materials. If suspect materials are identified, arrange specialist testing before going unconditional. Use the results to inform your offer.
