Sections of a Christchurch park may be closed for three weeks after asbestos was discovered in the soil.
Christchurch City Council cordoned sites comprised of trees and plantings around the edge of Kyle Park in Hornby on Friday, after testing found asbestos fibres in the garden.
Air testing is taking place at those sites, while soil is being tested in other areas of the park.
Test results won't be known until the end of the week, council parks unit manager Andrew Rutledge says.
"The work may take up to two weeks following the testing," he told NZ Newswire today.
"All the safety precautions will be in place until we get to the end of that process."
The cordons will be altered if necessary, he said.
"Ongoing testing will tell us as we move out through the park.
"It's unlikely that we would need to cordon off the entire park because in the situation where it's grass, it's stable."
Early testing in the sports field areas had shown no sign of asbestos.
"We currently have no evidence to justify full closure of the park."
The asbestos had appeared because the park used to be the site of a landfill which closed in 1981, Mr Rutledge said.
Canterbury Medical Officer of Health Dr Alistair Humphrey says the risk to park users is close to zero.
