Asbestos Storm Damage NZ: What to Do After a Cyclone

• Buildings built or renovated before 2000 may contain asbestos

• Storm damage can make asbestos materials friable and dangerous

• Do not clean up debris until asbestos risk is assessed

• DIY cleanup methods like water blasting or sweeping can spread fibres

• Professional inspection is the safest way to proceed

Severe weather events like cyclones can cause significant damage to homes and buildings across New Zealand. While most people focus on visible damage like broken roofs or flooding, there is often a hidden risk that many overlook — asbestos exposure.

If your property was built or renovated before the year 2000, there is a high likelihood that some materials may contain asbestos. When these materials are damaged by wind, rain, or debris, they can release airborne fibres that pose serious health risks when inhaled.

⚠️ If your property has been damaged, do not begin cleanup until asbestos risk has been assessed.

In New Zealand, any building constructed or renovated before 1 January 2000 should be considered at risk of containing asbestos.

Asbestos was commonly used in:

• Roofing and cladding

• Soffits and eaves

• Vinyl flooring and adhesives

• Textured ceilings and wall linings

• Pipe insulation and backing boards

Even if a building appears modern, renovations completed before 2000 may have introduced asbestos-containing materials that are now hidden within the structure.

Storm damage can break, disturb, or weaken these materials — significantly increasing the risk of fibre release, especially as materials dry out after flooding.

Cyclones often expose materials that were previously sealed or stable. Based on experience across Hawke’s Bay, Gisborne, Taupō and Manawatū, the most common risk areas include:

• Asbestos-cement roofing (including older sheets and decramastic systems)

• Soffits, eaves, and exterior cladding

• Vinyl tiles and sheet flooring (including asbestos-containing adhesives)

• Textured ceilings (e.g. popcorn ceilings)

• Wall linings in wet areas such as bathrooms and laundries

• Pipe lagging and insulation

• Backing boards behind fireplaces or heaters

One of the biggest risks comes from well-intentioned cleanup efforts.

Avoid the following:

• Do not water blast roofing or cladding

• Do not sweep or vacuum debris

• Do not cut, sand, or break materials

• Do not assume materials are safe based on appearance

These actions can release microscopic asbestos fibres into the air, increasing exposure risk for you, your family, or workers on site.

If your property has been impacted:

✔ Keep people away from damaged areas

✔ Avoid disturbing any suspect materials

✔ Limit access to prevent further contamination

✔ Arrange a professional asbestos inspection

If materials are wet, lightly misting can help suppress fibres — but avoid excessive water that may spread contamination.

For homeowners and businesses (PCBUs), there are legal responsibilities under the Health and Safety at Work (Asbestos) Regulations 2016.

You must:

• Identify asbestos risks

• Ensure safe management of materials

• Obtain proper assessments before repair or demolition

A professional asbestos survey provides:

• Identification of asbestos-containing materials

• Assessment of condition and risk

• Clear recommendations for safe management or removal

After a cyclone, there is often pressure to clean up quickly — but this is where mistakes happen.

Independent asbestos testing ensures:

• Accurate identification of materials

• No conflict of interest (unlike removal companies)

• Clear, compliant advice aligned with WorkSafe requirements

Air monitoring can also be used during cleanup or removal to confirm that fibre levels remain safe.

Storm recovery can be stressful, and it’s natural to want to get things back to normal as quickly as possible.

However, disturbing asbestos without proper assessment can create long-term health risks that far outweigh short-term convenience.

Taking the time to assess asbestos risks properly ensures:

• Safe cleanup and repairs

• Compliance with regulations

• Protection for occupants, workers, and neighbours

If your property has been affected by a cyclone, don’t take risks with asbestos.
