Several retailers with licenses to sell legal highs have been shut down for breaking new rules related to their sale.
The Psychoactive Substances Regulatory Authority says it has suspended licences in Hawera and Dunedin after evidence the retailers were not complying with the Psychoactive Substances Act.
Authority manager Donald Hannah says the licenses will remain suspended pending an investigation into concerns the businesses were selling food and drink which is forbidden under the Act.
He says in another case, an application for an interim retail licence in Dunedin has been refused, while a retailer in Waikato will be prosecuted for breaching the conditions of his license.
Dr Hannah says the new law has substantially reduced the number of outlets selling legal highs.
