A report has been lodged with Dargaville police.
Christiansen said thankfully, no structures were broken and that volunteers were able to clear the damage before the start of class yesterday morning.
"With further funding needing to be spent on more security measures, this impacts on our whanau and children as this funding would normally go towards learning and educational equipment for our tamariki at centre," she said.
There are about 20 children at the fees-free playcentre maintained by families through cleaning, planting and other work.
"Just wanting to ask the community to respect others property. So much hard work has gone into our playcentre and I know playcentres around the country put so much time and effort into keeping there centres up to optimal functioning to get the best and most for our tamariki," Christiansen said.
She said apart from an allocation of money from the Ministry of Education, volunteers rely on donations to keep the playcentre going.
