The Ministry of Business, Innovation and Employment issued a public recall for rainbow play sand from Educational Colours and coloured sand from Creatistics after tests found tremolite and chrysotile, a naturally occurring asbestos.

Anyone wishing to dispose of the recalled coloured sand products was advised to contact their local council.

People were warned not to dispose of these items in any kerbside bins.

From Tuesday, November 18, householders could drop the products off at Te Maunga Transfer Station on Truman Lane, Mount Maunganui, during opening hours.

Te Maunga Transfer Station was open seven days a week, Monday to Friday from 7.30am to 5pm, and Saturday, Sunday and public holidays from 9am to 5pm.

A clearly marked wheelie bin was available at the transfer station for the material.

Households were required to check in with weighbridge staff on arrival, who directed them to the safe drop-off point.

To prepare the sand for drop-off, products had to be in a sealed airtight container and double-bagged in sealed plastic bags or wrapped in plastic and taped securely.

WorkSafe provided further guidance on how to handle asbestos safely.

Schools, early childhood centres, retailers, workplaces and other non-residential sources were advised to arrange disposal through a licensed asbestos removal specialist.

Registered providers could be found on the WorkSafe website.
