Removing old vinyl flooring sounds straightforward — but if your home was built before the mid-1980s, that vinyl may have an asbestos-containing backing or adhesive, and the rules around removing it are strict. In New Zealand, whether you can legally do this yourself depends on the type and condition of the asbestos material, and the quantity involved. Getting it wrong can put your family's health at serious risk, so it pays to understand the rules before you lift a single tile.
Why Old Vinyl Flooring Can Contain Asbestos
Asbestos was widely used in New Zealand building materials until it was phased out in the late 1980s. Vinyl floor tiles and sheet vinyl from this era often contained asbestos fibres in the backing layer or the black mastic adhesive used to bond them to the subfloor. These materials are classed as non-friable asbestos (also called bonded asbestos) when they are in good condition — meaning the fibres are locked into a solid matrix and are less likely to become airborne under normal circumstances.
However, when you cut, sand, scrape, or aggressively disturb this material, fibres can be released into the air. Inhaling asbestos fibres is the cause of serious diseases including mesothelioma, asbestosis, and lung cancer — conditions that may not appear for decades after exposure.
NZ Legal Framework: What Are You Allowed to Do?
In New Zealand, asbestos removal is governed by the Health and Safety at Work (Asbestos) Regulations 2016, administered by WorkSafe NZ. The rules distinguish between two classes of removal work:
| Class | Type of Asbestos | Who Can Do It |
|---|---|---|
| Class A | Friable asbestos (loose, crumbly, easily crumbled by hand) | Licensed Class A removalist only |
| Class B | Non-friable asbestos (bonded, in good condition) up to 10 m² | Homeowner on their own home, or licensed Class B removalist |
| Class B (>10 m²) | Non-friable asbestos over 10 m² | Licensed Class B or Class A removalist |
So, if your vinyl flooring is non-friable, in good condition, and covers less than 10 m², you may legally remove it yourself — but only if you are the owner-occupier working on your own home. If the area exceeds 10 m², or the material is damaged, deteriorating, or friable, you must hire a licensed asbestos removalist.
Important: Always confirm the rules with WorkSafe NZ and your local council before starting any asbestos removal work.
Step 1: Get the Material Tested First
Before assuming your old vinyl contains asbestos, have it tested by an accredited laboratory. Do not attempt to identify asbestos by sight — it is impossible to tell without testing. A qualified asbestos assessor can take samples safely and send them for analysis. This step is strongly recommended and may save you significant cost and risk.
If You Proceed Yourself (Under 10 m², Non-Friable)
If testing confirms non-friable asbestos and the area is under 10 m², here is the general safe-work approach based on WorkSafe NZ guidance:
- Do not sand, grind, or dry-scrape the material — this releases fibres.
- Wet the material thoroughly before and during removal to suppress dust.
- Wear a properly fitted P2 respirator (not a dust mask), disposable coveralls, gloves, and safety glasses.
- Seal off the work area and keep others — especially children — well away.
- Double-bag all waste in heavy-duty polythene bags, label them clearly as asbestos waste, and seal with tape.
- Do not vacuum with a standard vacuum cleaner — use a H-class (HEPA) vacuum only.
- Dispose of asbestos waste at an approved disposal facility — contact your local council for the nearest site, as requirements vary by region.
- Clean up with damp cloths, not dry sweeping.

What About the Black Mastic Adhesive?
The black bitumen-based adhesive beneath old vinyl tiles frequently contains asbestos. This adhesive is notoriously difficult to remove without grinding or scraping aggressively — both of which are high-risk activities. In many cases, the safest and most practical option is to encapsulate the adhesive by laying new flooring over the top, rather than removing it. Talk to a flooring professional or asbestos assessor about this option.
Disposing of Asbestos Waste in NZ
Asbestos waste cannot go in your general rubbish or skip bin. You must take it to a council-approved landfill that accepts asbestos. Ring your local council or check their website for the correct facility and any pre-notification requirements. Illegal dumping of asbestos is a serious offence under NZ law.
When to Call a Professional
You should always hire a licensed asbestos removalist if:
- The area to be removed is greater than 10 m²
- The material is damaged, crumbling, or friable
- The black adhesive needs to be ground or scraped off
- You are not the owner-occupier (e.g., a landlord with tenants — note Healthy Homes Standards obligations)
- You have any doubt about the condition or type of asbestos present
- You simply don't feel comfortable doing this work safely
A licensed professional will have the correct equipment, training, and insurance — and will handle disposal for you. You can find qualified asbestos removal specialists in your area on tradedirectory.co.nz.
