A Taupo secondary school has been left reeling after discovering more than 100 shattered windows around its premises.
Senior management at Tauhara College received a call from the school caretakers at the weekend reporting 134 smashed windows.
Principal Peter Gould said police had caught the culprits, who were a group of at least three primary school-aged children.
"We haven't received an official police report but we understand the oldest of the children was 8."
He said it was not the first time young children had been caught at the school.
