A world-first study led by the Auckland University of Technology is set to examine whether fibres in contaminated children’s play sand can become airborne and inhaled.
The research comes after tremolite asbestos was discovered in coloured play sand used in homes and schools across New Zealand in November last year.
The findings triggered product recalls, school closures and extensive clean-ups to limit potential exposure to the cancer-causing substance.
“The research will either confirm the fibres do not become airborne when the sand is played with, which presents a much lower risk and will hopefully reassure worried parents and caregivers,” she said.
“Or it will provide evidence that the sand does, in fact, release fibres, which would support further testing to assess risk and also provide a record of the event, should asbestos-related disease occur in the future from sand use.
“At this stage, we don’t know what the answer will be, but we really hope it’s not airborne.”

Berry, who is also chairwoman of the Mesothelioma Support and Asbestos Awareness Trust, said the research is dedicated to co-founder Leonie Metcalfe, who died earlier this month.
“Leonie was New Zealand’s longest surviving mesothelioma patient and a driving force of the Mesothelioma Support and Asbestos Awareness Trust Charity,” Berry said.
AUT deputy vice-chancellor research Mark Orams said the project highlights how scientific research can solve real-world problems.
“In addition to answering the question of whether asbestos found in these products is airborne, the research will help us better understand the level of risk to the children, teachers, parents and caregivers who have come into contact with these products in Aotearoa, Australia and across much of Europe,” he said.
The research is partially funded by AUT, WorkSafe New Zealand and the Ministry of Business, Innovation and Employment, with additional backing from industry groups in New Zealand and Australia.
Although New Zealand prohibits the import of asbestos-containing products unless permitted, there is no requirement to routinely test goods at the border.
