Pekerau Primary School acting principal Pat Boland said almost every flat surface of the playground — including the fake grass — was tagged.
"My guess was that it was out-of-towners doing the tagging, like dogs marking their territory," he says.
"It could have been really upsetting for the children to come back to school with a tagged playground."
But by the time school started back last week, the students were greeted with a fresh playground. Every tagged apparatus had been replaced.
Pat said the cost of replacement was significant and meant the school could spend money on other resources.
He said he was stunned at the kind gesture of the local businesses.
"I was really impressed. The level of community spirit here in Te Awamutu is incredible."
