Asbestos – it’s a word many New Zealanders associate with danger, but few know exactly what it is, or why it’s such a big deal. Whether you’re renovating, buying a house, or managing a property, understanding asbestos is key to protecting your health and avoiding costly mistakes.
Here’s everything you need to know about asbestos, explained in plain language.
What Is Asbestos?
Asbestos is a naturally occurring mineral made up of tiny, strong, and heat-resistant fibres. It was once considered a “miracle material” and widely used in thousands of building and industrial products — especially from the 1940s through to the 1980s.
In New Zealand, asbestos was used in everything from roofing and wall linings to pipe insulation and vinyl flooring.
Why Was It So Popular?
Asbestos was cheap, durable, and resistant to fire, water, and chemicals. That made it ideal for:
- Insulation
- Fireproofing
- Strengthening cement
- Soundproofing
- Industrial and construction materials
But as time went on, the health risks became impossible to ignore.
Why Is Asbestos Dangerous?
Asbestos becomes dangerous when it’s disturbed. The tiny fibres can break loose and become airborne — where they can be breathed in without you even knowing.
Once inside the lungs, asbestos fibres can cause serious illnesses, including:
- Asbestosis (scarring of the lung tissue)
- Lung cancer
- Mesothelioma (a rare and aggressive cancer linked to asbestos exposure)
- Pleural disease (thickening or fluid buildup around the lungs)
There is no safe level of exposure — which is why managing or removing asbestos must be done properly.
Where Is Asbestos Found in NZ Homes?
In New Zealand, asbestos can still be found in many homes and buildings built before 2000. Common places include:
- Ceilings (especially textured coatings)
- Vinyl flooring and black adhesives
- Wall linings and soffits
- Cladding and roofing
- Old insulation and pipe lagging
If you’re renovating or demolishing, a professional asbestos check is a must.
Is Asbestos Still Used in New Zealand?
No.
New Zealand banned the importation of asbestos-containing products in 2016. But because so many older homes and buildings still contain asbestos, it remains a significant health and safety issue.
Is Asbestos Still Used in New Zealand?
You can’t confirm asbestos just by looking at it. The only way to know for sure is through:
- Professional asbestos sampling
- Laboratory testing

Types of Asbestos
There are three main types of asbestos commonly found in NZ:
- Chrysotile (white asbestos): The most common type. Often found in ceilings, walls, floors.
- Amosite (brown asbestos): Often in cement sheeting and insulation.
- Crocidolite (blue asbestos): The most dangerous form. Often found in lagging, pipe insulation, and sprays.
Each type has different properties, but all are harmful if inhaled.
Get it tested
Asbestos isn’t always dangerous when left undisturbed — but once fibres become airborne, the health risks are serious. If you suspect it in your home or building, play it safe: get it tested by professionals.
