Removing asbestos-containing textured ceiling coating yourself — even using wet methods — is not legal in New Zealand. Regardless of the technique used, this type of work is classified as licensed asbestos removal under NZ health and safety law, and must be carried out by a trained and licensed professional. Here's what you need to know to stay safe and on the right side of the law.
What Is Asbestos Textured Ceiling Coating?
Textured ceiling coatings — sometimes called "stipple," "popcorn," or "acoustic" ceilings — were commonly applied in NZ homes built or renovated between the 1940s and late 1980s. Many of these products contained chrysotile (white) asbestos as a binding and strengthening agent. If your home was built or renovated before 1990, there is a real possibility your textured ceiling contains asbestos.
Before any removal work begins, you should have the material tested by an accredited laboratory. A licensed asbestos assessor can take samples safely and arrange testing. Do not attempt to sample the material yourself.
What Are Wet Methods — and Why Aren't They Enough?
Wet methods involve saturating the material with water (sometimes mixed with a surfactant or wetting agent) before removal, to suppress the release of airborne fibres. In some limited asbestos-related contexts, wet methods do reduce fibre release compared to dry removal. However, in New Zealand:
- Textured ceiling coatings are classified as friable asbestos-containing material (ACM) once disturbed — meaning fibres are easily released into the air.
- Friable ACM removal is Class A licensed asbestos removal work under the Health and Safety at Work (Asbestos) Regulations 2016, regardless of the method used.
- Wet methods do not reduce the legal classification of the work or make it safe for an unlicensed person to carry out.
- Even with wetting, microscopic asbestos fibres can still become airborne and be inhaled — causing serious diseases including mesothelioma, asbestosis, and lung cancer, often decades later.
WorkSafe NZ is the regulatory authority for asbestos in New Zealand and makes clear that homeowners cannot legally remove friable ACM themselves.
What Does the Law Actually Say?
Under the Health and Safety at Work (Asbestos) Regulations 2016, asbestos removal work is split into two classes:
| Class | Type of Work | Who Can Do It |
|---|---|---|
| Class A | Friable ACM (e.g. textured coatings, sprayed asbestos) | Licensed Class A removalist only |
| Class B | Non-friable ACM (e.g. intact fibro sheeting) | Licensed Class B removalist (or homeowner in limited circumstances — see below) |
Textured ceiling coatings fall firmly into Class A. There are no exemptions that allow a homeowner to remove Class A material themselves, wet methods or otherwise.
For Class B non-friable materials, homeowners working on their own home may be able to carry out minor removal in some circumstances, but you should always confirm this with WorkSafe NZ and your local council before proceeding.
What Happens If You Do It Yourself?
Carrying out unlicensed asbestos removal exposes you to serious risks:
- Health risk: Inhaling asbestos fibres can cause fatal diseases with no safe exposure threshold.
- Legal risk: Breaching the Asbestos Regulations can result in significant fines under the Health and Safety at Work Act 2015.
- Property risk: Contaminating your home with asbestos fibres can make it extremely costly to remediate and may affect its sale value.
- Disposal risk: Asbestos waste must be disposed of at an approved facility — illegal dumping carries heavy penalties.
What Should You Do Instead?
- Don't disturb the ceiling. If the coating is in good condition and not being damaged, it may be safer to leave it in place or encapsulate it — discuss options with a licensed asbestos assessor.
- Get the material tested by an accredited assessor before any renovation work.
- Hire a licensed Class A asbestos removalist. They will prepare a removal control plan, use appropriate PPE and containment, carry out air monitoring, and dispose of waste legally.
- Check for a building consent requirement. Depending on the scope of work following removal (e.g. ceiling replacement), a building consent may be needed. Always check with your local council — MBIE Building Performance has guidance on consent requirements and Schedule 1 exemptions.

When to Call a Professional
You should contact a licensed asbestos professional immediately if:
- You suspect your ceiling contains asbestos and are planning any renovation.
- The ceiling has been damaged, is flaking, or is deteriorating.
- You have already disturbed the material — stop work, leave the area, and seek advice from WorkSafe NZ.
- You are buying or selling a home with pre-1990 textured ceilings.
Safety note: Never sand, scrape, drill, or water-blast a ceiling you suspect contains asbestos. Even brief exposure to asbestos fibres carries long-term health risks.
