Pieces of asbestos containing material (ACM) have been found on the Tāmaki Estuary coastline between Karaka Bay and Panmure Wharf. The largest amounts of ACM have been found at Glendowie Bay.
The ACM found is considered a low risk to health. However, you should not touch, collect or pick up any material that looks like pieces of fibre cement board.
Call 09 301 0101 or email environmentalhealth@aucklandcouncil.govt.nz with photos of the location if you find material you think is ACM.
We are monitoring and removing visible ACM and using an external team of experts to do a detailed site investigation (DSI).

Asbestos is a naturally occurring mineral made up of small, strong fibres. It was widely used in building materials in New Zealand between the 1940s and mid-1980s.
The building industry mostly stopped using asbestos in New Zealand by the late 1980s. A total ban was applied on its use in 2016.
An ACM is a material that contains more than 1 per cent of asbestos. Examples of ACMs include:
If you think you have materials that contain asbestos, you should have them tested by a professional.
Visit IANZ and search 'asbestos' for a list of accredited asbestos testing services. This will help you decide how to handle the materials.
We do not provide an asbestos testing service for the public.
Examples of ACM found on Auckland’s eastern coastline
Use a professional asbestos removal company to dispose of asbestos. Visit Worksafe for a list of certified asbestos removers.
Transfer stations in Auckland do not accept asbestos.
Our staff and contractors will not collect items they think contain asbestos. This includes items you put out for inorganic collections.

'Friable' asbestos can be crumbled into powder by hand. This can release toxic asbestos fibres into the air. If inhaled, these fibres can cause serious health risks like mesothelioma A type of cancer that mostly affects the lining of the lungs. and lung cancer.
'Non-friable' asbestos is less of a health risk. It is secured in a solid material like cement and cannot crumble by hand. This material only becomes hazardous if it crumbles.
Health risks from asbestos are at their lowest when it is wet.
ACM found on the beaches and in mudflats Muddy areas found along the coast that are covered with water at high tide and exposed at low tide. between Karaka Bay and Panmure Wharf are non-friable. This material is a low health risk when left untouched.
Health risks come from inhaling asbestos fibres. These are unlikely to be released from materials found on these beaches unless they dry and crumble.
Health risks from ACM on these beaches are further reduced because:
Most ACM found on our beaches is in the form of old building materials like fibre cement board.
If you pick up a piece of ACM and take it home, there is a higher risk that fibres will be released. This happens when the material dries out and if the cement crumbles.
Do not pick up any material that could be ACM.
It is still safe to visit beaches on the Tāmaki Estuary.
The material found on these beaches is a form of bonded asbestos (asbestos-cement) which is a low-level health risk.

Our Environmental Health team began removing visible ACM in February 2025 at:
Professional asbestos removalists completed a round of clean-ups in June 2025 at:
We will continue ongoing and regular ACM clean-ups at beaches in these areas.
Email healthenforcement@aucklandcouncil.govt.nz for our clean-up schedules.
