Four people were arrested at Christmas in the Park in Auckland last night.
But police are pleased with the general behaviour of the crowd.
The event, the 22nd Coca-Cola Christmas in the Park, was held at the Auckland Domain and was an alcohol-free event.
"There were minimal issues during the concert and good use was made of public transport for patrons travelling to and from the venue," said Auckland Police operations manager Inspector Peter Gibson.
The event would continue to be alcohol-free in future.
