The children's coloured sand recalls started quietly in November 2025. By the middle of 2026 they had become the most significant consumer asbestos event in Australia and New Zealand in years: dozens of recalled product lines, around 50 New Zealand schools and early childhood centres closed for cleaning, a Commerce Commission investigation, and an outright ban on children's play sand under active consideration.
The turning point was a piece of research from Auckland University of Technology, and it hung on one question. Does the sand actually release fibres when a child plays with it?
How the recalls unfolded
The first recalls landed on 12 and 13 November 2025, expanding through Kmart and Target lines on 16 November, sensory activity sets on 5 December, and CleverPatch products on 8 December. A further recall of HTI-branded scented sand followed on 12 May 2026. Independent testing commissioned by FAMANZ later identified more contaminated products, including a 14-piece Sandcastle Building Set and blue, green and pink Magic Sand.
The recalled range covers exactly what you would expect to find in a primary school art cupboard or a childcare sensory table: Kadink sand and decorative sand, Educational Colours Rainbow Sand, Creatistics coloured sand, Paw Patrol, Bluey and Frozen 2 sensory activity sets, Anko sand ornament kits, MIKI sand art sets and Kidsplay craft sand party packs.
Two asbestos types were identified. Tremolite, a naturally occurring contaminant of the mineral source, and chrysotile, found in Kidsplay products. Other samples contained unidentified mineral fibres consistent with tremolite. The contamination is understood to trace back to the quarried mineral used to make the sand rather than to anything in the manufacturing process, which is why the same products triggered recalls in a string of other countries.
The advice that held for eight months
Throughout this period the official position from Australian and New Zealand agencies was reassuring in tone. The standard line, which appeared on regulator alerts including SafeWork SA's, was that respirable asbestos fibres were unlikely to be released from the sand in its current state unless it was processed by mechanical means such as crushing or pulverising.
That framing shaped how thousands of institutions responded. If fibres only release under crushing, then a sealed packet at the back of a store cupboard is a disposal problem rather than an exposure problem.
Reporting by the NZ Herald later established that the "unlikely to become airborne" line traced back to a risk assessment commissioned by the supplier, Educational Colours, rather than to independent testing. Regulators on both sides of the Tasman had been relaying a supplier-funded conclusion as official public health advice.
What AUT actually did
Associate Professor Terri-Ann Berry and her team at AUT's School of Future Environments set out to test the assumption directly. In March 2026, inside a controlled asbestos enclosure, a licensed asbestos removalist in full protective equipment simulated children's play using samples of recalled sand previously sold in New Zealand. Air samples were collected from three locations and analysed independently by laboratories in two countries: Eurofins in the United States and the University of Torino in Italy.
The results were released publicly in July 2026. Both tremolite and chrysotile fibres were released into the air during simulated play from some of the sand products tested. Craft sands released fibres at low, moderate and high play intensity alike, so fibre release was not a function of vigorous handling. Moulding sands, by contrast, did not release detectable fibres in the tests.
Berry's team also flagged a caveat that cuts the other way. The detection limits achievable in the study sat above standard asbestos clearance criteria, so a negative result cannot be read as confirmation that a product is safe.
The findings were shared with public health officials and regulators in both countries before publication. MBIE, WorkSafe New Zealand, the Ministry of Education and the Ministry of Health have all acknowledged the study.
Why this matters beyond the sand
The specific products are being dealt with. The structural lesson is broader, and it applies to anyone who relies on a supplier's safety documentation.
The AU/NZ product safety system defaulted to a risk assessment produced by the party with the strongest commercial interest in a low-risk finding. That assessment then propagated across government alerts, school communications and council disposal advice. It took an independent university, an asbestos enclosure and two overseas laboratories nearly eight months to test the claim.
If you manage a property portfolio, the parallel is direct. A supplier declaration that a material is asbestos-free is a commercial assurance, not a technical one. The same reasoning applies to imported building products, imported plant and equipment with gaskets or friction components, and bulk landscaping material. All of those are areas where AU/NZ has repeatedly found asbestos arriving despite a total ban.
What schools, childcare centres and facilities managers should do now
If recalled product may have been used or stored in your facility:
- Stop using it and restrict access to the area. Do not sweep, vacuum or tidy the space first. A standard vacuum cleaner will disperse fibres rather than capture them.
- Engage a licensed asbestos assessor or competent person to assess the area and decide what cleaning or removal is needed. This is a technical judgement, not a caretaking task, and given the AUT findings it should not be short-cut on the basis of the older "low risk unless crushed" advice.
- Handle unopened product as asbestos waste. Place it in 200-micron plastic bags marked with asbestos warnings and dispose of it at a facility licensed to accept asbestos waste. It does not belong in general waste.
- For spilled sand on hard surfaces, use P2 respiratory protection, disposable gloves and eye protection, with wet-spray methods rather than dry sweeping or vacuuming, and dispose of the material in labelled asbestos waste containers.
- Document what you did and when. With the Commerce Commission investigating and further regulatory action likely, being able to show a clear response timeline matters.
- Talk to parents and staff early and plainly. The New Zealand experience is that facilities which communicated late faced much harder conversations than those which got ahead of it.
Where this is heading
Three threads are still live.
The Commerce Commission is investigating what New Zealand consumers were told about these products. That line of inquiry goes directly to the supplier-commissioned risk assessment and how it came to be repeated as official advice.
An outright ban on children's play sand is under consideration in New Zealand, and the AUT findings make comparable Australian action more likely. Facilities should not assume the current recall list is final. FAMANZ's independent testing has already extended it once.
Most significantly, the episode has put the product-safety regime itself under scrutiny. Neither country currently requires routine asbestos testing of imported consumer goods with mineral or stone content, despite both maintaining a total prohibition on asbestos importation. The sand recalls are the second major demonstration in recent years, after imported building products and vehicle components, that a ban at the border is only as good as the testing behind it.
For duty holders the practical takeaway is unglamorous but durable. Treat supplier assurances as a starting point rather than an endpoint, keep a record of what you relied on and why, and when independent evidence contradicts the official line, go with the evidence.
