Rotorua mayor Steve Chadwick wants the government to review legislation around psychoactive substances and give councils the power to implement an outright ban on their sale.
In a letter sent to the Associate Minister of Health, Peter Dunne, Mrs Chadwick described current legislation as "manifestly inadequate."
"Rotorua District Council wants the government to let local communities decide whether or not to allow the sale of so-called legal high products in their cities and districts," she said.
Mrs Chadwick said her council was concerned that the current legislation had been introduced without local government consultation, despite councils' regulatory roles and the potential impact on local communities.
She said the Productivity Commission's recommendation that central government should collaborate with local government on such legislation had been ignored.
