Asbestos is a fibrous mineral used widely in New Zealand building materials until it was progressively banned, which presents a health risk when disturbed and releases fibres.
Common in properties built or renovated before the late 1980s: Fibrolite and other fibre cement cladding and roofing, vinyl floor tiles and backing, textured ceilings, pipe lagging, and around old wet-back and heating installations.
Undisturbed and in good condition, asbestos is generally not an immediate hazard. The risk arises when it is disturbed — during renovation, demolition or maintenance.
For anyone renovating, there are legal obligations. A person conducting a business or undertaking has duties under the Health and Safety at Work (Asbestos) Regulations 2016, including identifying asbestos before work that may disturb it, and using a licensed removalist for certain work.
Investors doing renovation work are frequently caught by these obligations without realising.
Asbestos removal is specialised and expensive, and it can substantially change a renovation budget. Discovering it mid-project is worse than knowing beforehand.
A pre-1990s property should be assumed to contain asbestos until surveyed. Budget for a survey before any significant renovation of an older property.
DIY removal is restricted. Certain asbestos work requires a licensed removalist regardless of who owns the property.
