Key points at a glance
- Asbestos is common in homes built or renovated before the year 2000.
- The Health and Safety at Work (Asbestos) Regulations 2016 govern asbestos work.
- Removing over 10m² of non-friable asbestos, or any friable asbestos, needs a licensed removalist.
- Disturbing asbestos without proper controls is a serious health risk.
Where asbestos is found
Asbestos was widely used in New Zealand building products until around 2000 — in cladding, soffits, textured ceilings, vinyl and lino, roofing, and around old hot-water systems. Materials in good condition and left undisturbed are generally low-risk; the danger comes when they are cut, drilled, sanded or broken and fibres become airborne.
Before renovating or demolishing an older home, it is wise to get an asbestos survey so you know what you are dealing with.
When a licensed removalist is required
Under the Health and Safety at Work (Asbestos) Regulations 2016, removing more than 10 square metres of non-friable (bonded) asbestos, or any amount of friable asbestos, must be done by a licensed asbestos removalist. Friable asbestos work requires the highest class of licence.
Licensed removalists follow strict controls for containment, protective equipment, air monitoring and disposal at approved facilities. Do not attempt to remove significant asbestos yourself.
For homeowners
- Assume pre-2000 materials may contain asbestos — get a survey before renovating.
- Use a licensed removalist for anything beyond a very small, bonded amount.
- Never sand, cut or waterblast material that may contain asbestos.
For tradespeople
- Identify and assess asbestos risk before disturbing pre-2000 materials.
- Use a licensed removalist where the regulations require one.
- Follow containment, PPE, air-monitoring and approved-disposal requirements.
