Removing asbestos soffit lining yourself in New Zealand is not straightforward and, in most cases, not legal without the right licence. Even a "small" piece of asbestos-containing material (ACM) is subject to strict health and safety regulations under the Health and Safety at Work (Asbestos) Regulations 2016. Before you pick up a screwdriver, read this carefully — the risks to your health and the health of your family are serious.
Why Asbestos Soffits Are a Concern
Many New Zealand homes built before the mid-1980s used asbestos cement (AC) sheeting for soffit linings under eaves, carports, and garages. This material was popular because it was durable and fire-resistant. When it is in good condition and left undisturbed, the risk is relatively low. However, the moment you cut, drill, break, or sand it, you release asbestos fibres into the air — and inhaling those fibres can cause serious diseases including mesothelioma and asbestosis, often decades later.
What the Law Says in New Zealand
Under the Health and Safety at Work (Asbestos) Regulations 2016, asbestos removal work is divided into two classes:
| Class | Type of Work | Who Can Do It |
|---|---|---|
| Class A | Friable asbestos or any amount of non-friable ACM over 10 m² | Licensed Class A removalist only |
| Class B | Non-friable ACM of 10 m² or less | Licensed Class B removalist (or Class A) |
| Unlicensed | Non-friable ACM of less than 10 m² in some circumstances | Homeowner may be permitted — see below |
The critical distinction is friable vs non-friable. Asbestos cement soffit sheeting is generally considered non-friable (it doesn't crumble easily by hand). However, if it is weathered, damaged, or deteriorating, it may be treated as friable — in which case a Class A licensed removalist is legally required regardless of size.
WorkSafe NZ is the authority that sets and enforces these regulations, and their guidance is clear: even for small areas, you must follow strict procedures.
Can a Homeowner Legally Remove a Small Piece?
For non-friable ACM under 10 m² on your own home (not a rental or commercial property), the regulations do allow some unlicensed removal — but only if you follow all required safe work practices. This includes:
- Identifying the material first — you cannot assume it contains asbestos. Have a sample tested by an accredited laboratory, or hire a licensed asbestos assessor to inspect it.
- Wetting the material thoroughly before and during removal to suppress fibre release.
- Wearing the correct P2 (or higher) respirator — not a dust mask.
- Using disposable coveralls, gloves, and eye protection.
- Not using power tools — hand tools only, and even then, minimise breakage.
- Double-bagging all waste in clearly labelled asbestos disposal bags.
- Disposing of waste at an approved facility — contact your local council to find out where asbestos waste is accepted in your area.
- Cleaning up with a damp cloth or HEPA vacuum — never a standard vacuum cleaner.
Even if you are technically permitted to do this work yourself, it is strongly recommended that you hire a licensed professional. The consequences of getting it wrong — for your health and the health of those around you — are severe and irreversible.
Rental Properties and Healthy Homes
If the property is a rental, the rules are stricter. Landlords have obligations under the Tenancy Services Healthy Homes standards and broader health and safety duties. Any asbestos work on a rental should be carried out by a licensed removalist.
Getting the Material Tested First
Before doing anything, confirm whether your soffit actually contains asbestos. Not all older sheeting does. A licensed asbestos assessor can take a sample safely and have it analysed. This is money well spent — if it comes back clear, you have no problem. If it does contain asbestos, you'll have a written record and professional advice on next steps.
BRANZ provides useful guidance on identifying common asbestos-containing materials found in NZ homes.
Does This Work Require a Building Consent?
Replacing soffit lining may or may not require a building consent, depending on the scope of work. Minor repair or like-for-like replacement of a small section may fall under Schedule 1 exemptions of the Building Act 2004 — but you should always confirm with your local council before starting. MBIE Building Performance has information on consent exemptions to help you understand the framework.
When to Call a Professional
You should hire a licensed asbestos removalist if:
- The soffit material is damaged, crumbling, or weathered.
- The area is 10 m² or larger.
- You are not confident in identifying or safely handling the material.
- The property is a rental or commercial building.
- You want peace of mind and a proper clearance certificate.
A licensed professional will also arrange for an independent clearance inspection after removal, giving you documented proof the area is safe. You can find qualified asbestos removal specialists in your area on tradedirectory.co.nz.
