The tower itself was found to have a rotting timber structure and the gel coating on the slide had worn off, exposing glass fibres.
The report recommended the slide be immediately closed, but a fibreglass specialist who looked at it afterwards confirmed it was still in good condition and could be kept open for use.
Council took immediate action to fix the rest of the issues, and the playground was then deemed to comply with safety regulations.
Day said they had hoped people would be able to continue using the playground until its full renewal later this year, but this latest accident meant they would have to review the equipment.
"The issue is rubbery shoes can catch on things, it's something I've dealt with as a parent on many outdoor slides," she said.
"But we do need to look at the gradient of the slide, and make sure we don't have something that's going to cause further problems.
"I have asked council staff to have a good look at it and consider whether it does need to be closed off."
Council spokesperson Richard MacLean said the equipment was more than 30 years old, but it was inspected and maintained regularly. He stressed the playground is safe to use.
MacLean said they were going to renew the existing sign and add more signage around the slide tower, with a focus on advising people to remove their shoes.
