Rotorua mayor Steve Chadwick has written to the Government requesting the power to completely ban the sale of psychoactive substances.
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 the current legislation had been introduced without local government consultation, despite councils' regulatory roles and the potential impact on local communities.
"We do understand that the Government now requires psychoactive substance products to be licensed and that the intention was to allow only less harmful products to be legally sold.
