A Complete Step-by-Step Guide to Asbestos Testing Before Renovation of a House in Auckland
A Complete Step-by-Step Guide to Asbestos Testing Before Renovation of a House in Auckland
If you own a house in Auckland and you’re planning a renovation, you need to think about one hidden hazard: asbestos-containing materials (ACMs).
Homes built or renovated before the late 1980s often have ceiling finishes, vinyl flooring, cement sheeting, cladding, or insulation that include asbestos.
Before you pull up floors, drill walls or rip out ceilings — you need to test for asbestos first. If you skip this step, you’re not only risking health but breaching the law under the Health and Safety at Work (Asbestos) Regulations 2016.
Here’s how to do it properly in Auckland-style, step by step — and why hiring a professional assessor is the smart move.
1️⃣ Step 1: Assume Risk & Prepare
Start by asking: when was the property built or last renovated?
If it’s pre-1990s or has materials like textured ceilings, vinyl tiles, cement sheets, there’s good reason to treat them as suspect.
According to the Auckland Council, any material that could contain asbestos must be treated with care and tested if you plan disturbance. Auckland Council+1
2️⃣ Step 2: Engage a Licensed Asbestos Assessor
Only a licensed professional should carry out an asbestos survey. They’ll perform a full inspection, take samples properly, and produce a detailed asbestos survey or management plan.
As the regulatory guidance explains: before renovation works that may disturb asbestos you must have a “refurbishment or demolition survey”. allclear.nz+1
3️⃣ Step 3: Sampling & Laboratory Testing
Here’s how the testing process works:
-
The assessor identifies suspect materials.
-
Samples are collected following strict protocols (e.g., dampening, protective gear, sealed double bags). fibres.co.nz+1
-
Samples are sent to an IANZ-accredited lab (eg. in Auckland) for analysis. Prolabs
-
The lab report shows whether asbestos is present, what type, and what concentration. Consultex Laboratories
If asbestos is found, you then decide whether to remove it or manage it in place — but you can’t proceed with renovation until this is resolved.
4️⃣ Step 4: Report & Decide What Happens Next
Once you have results, you’ll get a formal asbestos survey or sample report.
That document should map where ACMs are, their condition, and recommended actions. It becomes part of your renovation planning.
If removal is needed, you’ll then move into a licensed asbestos removal process.
5️⃣ Step 5: Document & Keep Records
Keep all paperwork: the survey report, sample analysis, correspondence with the assessor, removal quotations or management plan.
These records are key if you sell the house, get inspected, or need to prove compliance.
💡 Why You Should Always Use a Professional
-
Sampling or guessing on your own? One mistake and fibres can spread through your home.
-
Professionals know the regulations, have correct PPE, and use accredited labs.
-
If you DIY and something goes wrong (or inspectors show up) your project may stop, fines may apply, or you may expose your family to risk.
As one Auckland testing provider says: “If you think a material might be asbestos you should have it tested by a professional.” Auckland Council+1
✅ Final Word
Asbestos testing isn’t just a box-ticking exercise. It’s a vital step to protect your health, your home and your renovation investment.
If you’re planning to renovate in Auckland, get your asbestos survey done before you lift a floorboard or break a wall.
Hire a licensed assessor, submit samples, get your report — and then proceed with confidence.
