A group of four teenagers chose the wrong spot to carry out some tagging overnight, police say.
At about 12:30am a police staff member was taking a break from answering 111 calls outside the police northern communication centre in Auckland.
She was surprised to see the group tagging the bonnet of an expensive Audi opposite the centre, and then move on to tag an adjacent building.
When they realised they had been spotted they ran off but were soon rounded up by police patrols.
Police said the teens were this morning discussing their actions with Auckland officers.
