A Complete Step-by-Step Guide to Asbestos Removal Before Demolition in Auckland

A Complete Step-by-Step Guide to Asbestos Removal Before Demolition in Auckland

If you’re planning to demolish an older home in Auckland — stop before swinging the sledgehammer.
If your house was built before the late 1990s, there’s a strong chance asbestos is hiding somewhere: ceilings, soffits, linings, wall claddings, vinyl flooring, or even under eaves.

You can’t see it. You can’t smell it. But once it’s disturbed, asbestos fibres can float through the air — and into your lungs.
That’s why asbestos removal before demolition isn’t just best practice — it’s the law in New Zealand.

Here’s how professionals handle it safely, and what every Auckland homeowner or developer should know before tearing anything down.

🧱 Step 1: Get a Pre-Demolition Asbestos Survey

Before any demolition can begin, a licensed asbestos assessor must inspect the building.
They’ll:

  • Identify asbestos-containing materials (ACMs).

  • Take samples for laboratory testing.

  • Produce a detailed Asbestos Survey Report identifying what’s present, where it is, and what condition it’s in.

This survey forms the foundation of your demolition plan. No WorkSafe-compliant demolition can happen without it.

🧰 Step 2: Develop an Asbestos Removal Control Plan (ARCP)

Once asbestos is confirmed, a licensed Class A or B removalist prepares an Asbestos Removal Control Plan under the Health and Safety at Work (Asbestos) Regulations 2016.
This plan covers:

  • The exact location and type of asbestos.

  • Removal methods and containment.

  • PPE requirements.

  • Decontamination and waste disposal procedures.

WorkSafe NZ must be notified at least five working days before removal begins.

🧽 Step 3: Site Preparation and Isolation

The removal team sets up containment zones around affected areas.

  • Barriers, fencing, and warning signs are installed.

  • Air conditioning and power systems are isolated.

  • Surfaces and ground areas are covered with 200 µm plastic sheeting.

This ensures asbestos dust can’t travel into neighbouring homes, the air, or the soil.

🚿 Step 4: Wet Removal and Safe Handling

Licensed removalists work slowly and methodically using low-pressure water misting to keep fibres down.
They remove entire panels, sheets, or linings intact wherever possible — no breaking, grinding, or sanding allowed.
All material is double-bagged or wrapped in heavy-duty plastic, sealed, and labelled:

⚠️ CAUTION – ASBESTOS. DO NOT INHALE DUST.

All debris is handled as hazardous waste from the moment it’s detached.

🚛 Step 5: Waste Transport and Disposal

Asbestos waste is never thrown in a skip or normal landfill.
It must go through a licensed asbestos waste transporter to an approved facility like Redvale or Hampton Downs.
The removalist provides disposal receipts and a waste manifest as proof of compliance.

🧼 Step 6: Decontamination and Clearance

After all visible material is gone, workers undergo full decontamination — vacuuming with HEPA filters and carefully removing PPE.
Then, an independent licensed assessor conducts:

  • A visual inspection,

  • Air monitoring, and

  • Issues a Clearance Certificate confirming the site is safe for demolition crews to enter.

Only after that certificate is issued can the demolition proceed.

⚖️ Step 7: Legal Responsibilities Under NZ Law

Under the Health and Safety at Work (Asbestos) Regulations 2016:

  • Only licensed asbestos removalists can perform Class A or B removal.

  • WorkSafe NZ must be notified before removal starts.

  • Clearance certificates are mandatory before demolition or re-occupation.
    Failing to comply can result in heavy fines and criminal liability.

👷 Why You Need to Engage a Licensed Professional

It’s tempting to think, “It’s just a few sheets, I’ll do it myself.” But here’s the truth:

  • DIY asbestos removal is dangerous and often illegal.

  • Unlicensed handling voids insurance and can lead to prosecution.

  • Professionals protect you, your neighbours, and your workers — and ensure full documentation for your council or WorkSafe requirements.

Licensed companies in Auckland like Safety 1st Removals and Auditsure Ltd have trained staff, correct PPE, negative-pressure units, and strict WorkSafe compliance systems.

💬 Real Talk for Homeowners and Developers

Asbestos removal might feel like a cost you’d rather skip — but ignoring it can stop your entire project in its tracks.
WorkSafe has zero tolerance for unsafe demolition.

A professional team doesn’t just remove asbestos; they protect your health, your workers, and your reputation.

✅ Final Word

Before you start your Auckland demolition, remember: asbestos comes first, demolition comes second.
Get your survey done, hire a licensed removalist, and make sure you’ve got a Clearance Certificate in hand before the excavator rolls in.

It’s not just compliance — it’s common sense.
