Asbestos in NZ Homes: What to Do Before You Renovate (2026)
New Zealand has one of the highest rates of mesothelioma in the world -- a direct consequence of the widespread use of asbestos-containing materials in NZ building construction through to the late 1980s. If your home was built before 1990, there is a very real chance it contains asbestos. Before you start any renovation, this is what you need to know.
Where Asbestos Is Commonly Found in NZ Homes
| Location | Common asbestos-containing material |
| Ceilings | Textured (popcorn) coatings, flat sheet ceiling linings |
| Exterior cladding | Fibrolite (asbestos cement sheet), corrugated asbestos sheets |
| Eaves and soffits | Asbestos cement sheeting under eaves |
| Roof | Corrugated asbestos cement roofing (pre-1985 homes) |
| Floors | Vinyl floor tiles and the adhesive (black mastic) beneath them |
| Laundry and bathroom | Asbestos cement wall linings, backing to older vinyl flooring |
| Fences and outbuildings | Fibrolite fencing, shed walls and roofing |
| Important Asbestos that is in good condition and not disturbed does not pose an immediate health risk. The danger arises when asbestos-containing materials are cut, drilled, sanded, or broken during renovation work. Fibres released into the air can cause mesothelioma, asbestosis, and lung cancer if inhaled. |
Who Can Test for Asbestos in NZ?
Asbestos testing in NZ must be carried out by a licensed asbestos assessor under the Health and Safety at Work (Asbestos) Regulations 2016. They will take samples and have them analysed by an accredited laboratory.
- What a survey includes: visual inspection, sampling of suspected materials, laboratory analysis, and a written report identifying location and condition of any asbestos-containing materials
- Typical cost: $300 to $800 for a standard residential survey
- Result: a written register of asbestos locations and a risk assessment, which your contractor will need before starting work
What Are the Rules for Asbestos Removal in NZ?
Under the Health and Safety at Work (Asbestos) Regulations 2016, removal work is classified as either Class A or Class B:

Frequently Asked Questions
Do I need to remove asbestos before selling my NZ home?
No, there is no legal requirement to remove asbestos before selling. However, you should disclose the presence of known asbestos to potential buyers. Encapsulation (painting or sealing good-condition asbestos) is a common compliant alternative to full removal.
Can I remove asbestos myself in NZ?
For bonded asbestos under 10 sqm in a non-commercial setting, a homeowner can remove the material following strict WorkSafe guidelines. However, WorkSafe strongly recommends using a licensed removalist for all asbestos work.
