Hooning at Williams Domain in Whanganui East has caused largely superficial damage to the park.
Williams Domain is opposite Whanganui East School and is bordered by Tinirau, Patapu, Maketu and Hakeke streets.
A Whanganui District Council spokesperson said the incident, which is believed to have happened over the weekend, was not reported to the council and they had no information about the people or vehicle involved.
"Fortunately this time the damage is largely superficial and we believe it will rectify itself once the mower has been over it.
"It would have been worse if the ground was soft.
