The school principal said she had been told the asbestos-containing material was in a solid form, not crumbling or a dust-forming state, and the danger was "minimalistic".
About 80cu m of topsoil was trucked to the park on October 24 and October 25 from a private property and levelled for landscaping purposes on October 25.
Local and sports parks manager Mark Bowater refused to say where the soil came from, except that it came from a private property and the agreement with the landowner was for clean fill. No other soil from the property had been used on council or other sites, he said.
Mr Bowater said the asbestos material in the fill was believed to be low-risk because it was in a solid form.
Even so, he said, all of the fill was being removed to an approved landfill and the council was testing it in conjunction with the Auckland Regional Public Health Service.
Emma Griffiths, whose 5-year-old daughter attends the school, said it was unbelievable that the council would not check and test the soil before using it on the park.
She said her uncle was being buried in the United Kingdom tomorrow after dying within a year of being diagnosed with an asbestos-related disease at the age of 53.
The council, she said, should be penalised and make a donation to the school.
