The discovery of airborne asbestos fibres in children's play sand has prompted swift and coordinated action across New Zealand, raising serious concerns about product safety and long-term health risks for young children and their caregivers.
Testing conducted in a world-first study has confirmed that certain recalled coloured play sand products can release tremolite and chrysotile asbestos fibres into the air during normal play activities such as pouring, scooping and sifting. This development follows initial laboratory findings late last year that identified asbestos contamination in imported products sold in New Zealand and Australia.
Timeline of the Incident
The issue first came to light in November 2025 when routine testing in Australia detected asbestos in coloured play sand. New Zealand authorities were notified shortly afterwards, triggering immediate recalls and investigations. The Ministry of Business, Innovation and Employment (MBIE) and Product Safety NZ issued alerts for specific products, including EC Rainbow Sand and Creatistics Coloured Sand.
By mid-November 2025, additional testing led to expanded recalls involving Kmart Magic Sand products in various colours. Some batches were later cleared after further analysis, but many remained subject to voluntary and mandatory recalls. Schools and early childhood centres across the country began checking supplies, with dozens temporarily closing for testing and remediation.
In early July 2026, new research results confirmed that the asbestos fibres could become airborne under simulated play conditions, prompting urgent government meetings and heightened public awareness.
Understanding Asbestos and the Risks
Asbestos is a group of naturally occurring fibrous minerals known for their heat resistance and durability. The six main types include chrysotile (white asbestos) and tremolite, both identified in the contaminated sand samples. When fibres are inhaled, they can lodge in the lungs and cause serious diseases including asbestosis, lung cancer and mesothelioma, often decades after exposure.
Children are particularly vulnerable because their developing lungs are more susceptible to damage, and they may engage in prolonged play with the material. The risk arises primarily when fibres become respirable — small enough to be inhaled deep into the lungs — which the recent testing has now demonstrated can occur during typical children's activities.
Government and Agency Response
Multiple agencies have worked together on the response. MBIE's Product Safety team coordinated recalls and public alerts. WorkSafe has provided guidance on managing the material as friable asbestos-containing material in workplace and educational settings. The Ministry of Education issued specific advice for schools and early learning services. Health New Zealand has published health advice on exposure and cleanup.
Recalled products must be disposed of following strict protocols for asbestos waste. Standard household vacuums are not recommended as they may disperse fibres; professional cleaning or specialised disposal methods are advised for affected areas.

Impact on Families and Communities
Parents and caregivers across New Zealand have expressed shock and disappointment at the findings. Many households had purchased the brightly coloured sand for arts and crafts or sensory play, unaware of the hidden hazard. Early childhood centres and schools faced disruption as they identified and removed contaminated stock, with some facilities undergoing deep cleaning.
The incident has highlighted gaps in pre-market testing for imported consumer products, particularly those intended for children. Community discussions have focused on the need for greater transparency in supply chains and stronger border controls.
Cleanup and Safe Disposal Guidance
Official advice emphasises caution when handling recalled sand. Products should not be used and should be sealed in heavy-duty bags for disposal at authorised facilities. For homes or centres where the sand has been used, wet cleaning methods are preferred over dry sweeping or vacuuming to minimise airborne fibres.
Health New Zealand and WorkSafe recommend that anyone concerned about exposure consult a doctor, although the latency period for asbestos-related diseases means immediate symptoms are unlikely.
Broader Regulatory Implications
The episode has led to calls for enhanced product safety regulations, including mandatory testing for asbestos in imported craft and play materials. Stakeholders have pointed to the need for better international coordination, as similar products have been identified in other countries including the United Kingdom.
Industry groups and consumer advocates are urging importers and retailers to implement rigorous quality assurance processes before products reach the market.
International Context
New Zealand's experience mirrors developments in Australia, where hundreds of sites including schools were affected, and in other nations where recalls have been issued. The global nature of the supply chain for coloured play sand underscores the importance of harmonised safety standards.

Looking Ahead: Prevention and Consumer Advice
Consumers are advised to check product recall lists on the Product Safety NZ website and MBIE announcements. When purchasing play materials, opting for locally sourced or certified asbestos-free alternatives can reduce risk. Ongoing monitoring by regulators is expected as further testing continues.
The incident serves as a reminder of the importance of vigilance in product safety, particularly for items used by children.
