The short answer: sometimes yes, sometimes no
In New Zealand, you do **not** need a licence for every asbestos job. But if the work involves **higher-risk asbestos removal**, the law requires a **licensed asbestos removal specialist**. In practice, that means many homeowners can only DIY very small, low-risk jobs — and even then, only if they can do it safely and legally.
The key point is this: asbestos is regulated because the fibres can cause serious diseases, including mesothelioma, lung cancer, and asbestosis. Once asbestos-containing material is disturbed, broken, cut, drilled, sanded, or removed incorrectly, the risk increases fast.
If you’re unsure whether the material is asbestos, or whether the job is Class A or Class B removal, treat it as asbestos until proven otherwise and get professional advice.
What the rules are in New Zealand
Asbestos work in New Zealand is governed mainly by the **Health and Safety at Work (Asbestos) Regulations 2016** and wider workplace health and safety law. The rules distinguish between:
- **Asbestos removal work** that must be done by a licensed removalist - **Lower-risk work** that may be done by a competent person in limited situations - **Preparation, transport, and disposal** requirements that still apply even when a full licence is not required
For homeowners, the important practical distinction is between **licensed removal work** and **very small DIY-legal jobs**.
Licensed removal work
A **licensed asbestos removal specialist** is required for:
- **Class A asbestos removal** — generally higher-risk friable asbestos or asbestos that can be crumbled by hand pressure - **Class B asbestos removal** in cases above the legal threshold for non-licensed removal - Any job where the amount, condition, or location of the asbestos makes the work too risky to do without a licence
Class A work is the most tightly controlled and is usually done by trained, licensed professionals with proper containment, decontamination, waste handling, and air monitoring processes.
When DIY may be legal
Some asbestos work can be carried out by a homeowner, but only when it is **small, low-risk, and done carefully**. In general, this is limited to tasks such as:
- Removing a **small amount of non-friable asbestos cement** that is in good condition - Replacing a **small number of asbestos cement sheets** where the work can be done without breaking the material - Working on material that is firmly bonded and not likely to release fibres if handled correctly
Even when DIY is technically legal, it is not automatically wise. If the material is weathered, damaged, or in a difficult location, the safer option is usually to use a licensed specialist.
A practical guide: what needs a licence, what may not, and what to be careful about
| Type of asbestos job | Usually licence required? | DIY-legal? | Main caution | |---|---:|---:|---| | Friable asbestos, loose-fill, or material that crumbles easily | Yes | No | High fibre release risk | | Large-scale removal of asbestos cement roofing, cladding, fencing, or soffits | Often yes | Usually no | Size, height, and breakage risk | | Small, intact asbestos cement sheet removal | Sometimes no | Possibly, if low-risk and done correctly | Must avoid cutting, sanding, or breaking | | Drilling, cutting, grinding, or sanding asbestos materials | Often yes or strongly discouraged | Generally no | Creates hazardous dust | | Encapsulation or painting over asbestos in sound condition | Not usually removal work | Sometimes, with caution | Must use appropriate products and methods | | Disposal of asbestos waste | Not a licence issue by itself, but regulated | Yes, if handled correctly | Must package and dispose of properly |
If the job is more than a tiny, straightforward task, assume professional help is the safer choice.
Why “licensed” matters even if the material looks manageable
A lot of homeowners are surprised by how quickly a simple-looking job becomes non-compliant. The cost of a licensed specialist is not just labour; you’re paying for systems that reduce risk.
A properly qualified asbestos removal specialist should be able to manage:
- Site assessment and asbestos identification - Risk controls and job planning - Personal protective equipment and containment - Wet methods and dust suppression where appropriate - Safe removal without unnecessary breakage - Bagging, labelling, transport, and lawful disposal - Decontamination and, where needed, clearance procedures
This matters because asbestos dust is not always visible. A job that looks tidy can still contaminate roof spaces, wall cavities, tools, clothing, vehicles, and neighbouring areas.
The hidden risks of unlicensed asbestos work
1) Safety risk to your household and neighbours
The most obvious risk is health. But the less obvious one is how contamination spreads.
Unlicensed work can release fibres into:
- Ceiling cavities and roof spaces - Gardens and driveways - Dust on clothing and shoes - Nearby homes, especially on tight suburban sections - The vehicle used to carry waste
If asbestos debris is left behind or blown around by wind, the problem can become much larger than the original job.
2) Insurance problems
If you do unlicensed or careless asbestos work and there is a later claim, your insurer may ask:
- Was the work legal? - Was the material identified before removal? - Were the right safety steps used? - Was the waste disposed of correctly?
If the answer is no, you may face a reduced payout or a declined claim. That can matter if the job leads to contamination, fire damage, water damage, or a later health-and-safety complaint.
3) Resale and disclosure issues
Asbestos is common in older NZ homes, especially those built or altered before the late 1990s. If you remove asbestos yourself and the work is later questioned during a sale, you may need to explain:
- What was removed - Whether it was licensed work - Whether there is any remaining asbestos - Whether disposal records exist
Poorly documented or visibly patched areas can raise buyer concerns. A professional invoice, waste receipt, and any clearance paperwork can help support your position later.
4) Compliance and enforcement risk
If unlicensed removal is outside the legal limits, the work may breach workplace health and safety law, even in a residential setting. That can create problems if:
- A contractor later finds disturbed asbestos on site - Neighbours complain about dust or waste - Council or WorkSafe become involved - You later start renovation work and uncover the mess
In short, the risk is not just getting caught — it is being left with a site that is harder and more expensive to fix.
How to tell if you need a licensed specialist
Ask these questions before doing anything:
- Is the material definitely asbestos, or just suspected asbestos? - Is it **friable** or damaged? - How much material is involved? - Is it on a roof, in a wall cavity, under the house, or in another awkward location? - Would the work require cutting, drilling, breaking, or sanding? - Can the material be removed without creating dust or fragments? - Are there kids, pets, or neighbours nearby who could be exposed?
If you answer yes to any of the higher-risk points, get a licensed asbestos removal specialist to assess it.
What to check before hiring an asbestos removal specialist
In New Zealand, not all tradespeople who say they “do asbestos” are suitable for every job. Before you accept a quote, check:
- **Their licence status** for the type of asbestos work required - **Company experience** with residential jobs like yours - **Their health and safety plan** for the site - **How they will contain the work area** - **How waste will be packaged and disposed of** - **Whether they provide clearance documentation** if required - **What is included in the quote**: labour, containment, disposal, testing, and GST
A reputable specialist should be able to explain the process in plain English without pressuring you.
Get at least two or three written quotes
For most home jobs, it’s sensible to get multiple written quotes. This helps you compare more than just price.
Look for:
- Clear description of the asbestos material - What will be removed and what will remain - Job timing and expected duration - Disposal method and any landfill fees - Whether the quote includes scaffolding, access equipment, or making-good - Any exclusions or assumptions
Be wary of a quote that seems unusually cheap if it does not mention containment, waste disposal, or compliance paperwork.
What a professional asbestos job usually looks like
A licensed removalist will typically:
1. Inspect the site and confirm the material type 2. Plan the removal method based on risk 3. Set up exclusion zones and warning signs 4. Use the correct PPE and dust controls 5. Remove the material without unnecessary breakage 6. Bag and label the waste properly 7. Transport it to an approved disposal facility 8. Clean the area and complete any required clearance steps
This process is especially important in older NZ homes, baches, garages, fences, and roof replacements where asbestos cement products are still common.
When DIY is a bad idea, even if it might be legal
Even if a small job might fall within DIY-legal limits, hiring a professional is usually the better call if:
- You are not completely sure the material is asbestos cement - The sheets are cracked, weathered, or brittle - You need to work at height - The job is near a boundary or shared driveway - You are renovating and other trades will be on site - You want proper documentation for insurance or resale
A small mistake with asbestos can create a long-term problem, while the upfront cost of professional removal is often modest compared with remediation later.
The bottom line for NZ homeowners
You **do not always need** a licensed asbestos removal specialist in New Zealand, but you **do** need one for higher-risk asbestos work, especially friable material and larger or more complex removals. DIY is only legal in limited low-risk situations, and even then you still need to handle the job carefully and dispose of the waste properly.
If the material is damaged, the job is large, or you want certainty for insurance and resale, a licensed specialist is the safest choice. Get at least two written quotes, check credentials, and make sure the quote clearly covers containment, disposal, and any required paperwork.
When it comes to asbestos, the cheapest option is rarely the safest one.
