A Rotorua Lakes Council spokeswoman said after hours contractors notified council earlier last week after the police had reported to them that several gravestones had been damaged and a car bumper had been left at the scene.
She said Infracore staff had inspected and confirmed four headstones had been damaged.
It is likely that a stone mason will need to be contracted to lift the stones due to their weight, she said.

She said the headstones were in the older part of the cemetery and could be more than 30 years old.
Staff were now working through the process of identifying family members so they could be notified, she said.
