"You could be putting somebody's life at risk — they don't think of that.
"It's just the thought of it. Anything could have happened."
Noeleen Palmer of Hawera says her car was damaged at about 8.45pm when she was driving home from a St Mary's School concert. The new car, had only been driven three times, received a dented roof and chipped paint, leaving her footing a $300 excess on her insurance.
She reported the incident to the police and says she is disappointed, especially because it was a new car.
"It's the fright you get — and the fact that you could go over onto the wrong side of the road. It's dangerous."
Noeleen's daughter Christine Evans was following her mother and witnessed the incident. She posted it on social media and discovered they weren't the only ones hit. She says up to six cars were hit by stones between 6pm and 9pm that evening, with two cars receiving smashed windscreens.
