NZME photographer George Heard was in Queenstown on Saturday night when bars closed at midnight, as per Easter trading laws.
A video he took showed hundreds of people chanting in Ballarat St, one person falling from a tree in The Mall, and a man shaking a lamppost until it broke.
Boult said ratepayers would be left picking up the bill for the damage — "the last thing we need at the present time".
"We just don't countenance that behaviour and I can only hope the video reaches the police and they're able to identify the idiot concerned," he said.
Boult said he understood how the situation arose — by law, all bars must shut at midnight before Good Friday and Easter Sunday, meaning all patrons are ejected from premises at the same time.
