But Sandy and Ian Benjamin, from Rainbows Relics and Dean Abel, of Snow Brothers Auto Electric in Clyde St, have started a petition opposing the plan.
Mrs Benjamin said it had already gathered more than 150 signatures.
She said the petition was organised because the retailers, building owners and their customers were totally opposed to legal highs.
"Nobody wants these things in these streets or Whangarei full stop," Mrs Benjamin said.
"If people can't get off on life rather than these things that's sad, but we don't want them here. I've had retailers, building owners and customers all signing the petition."
The Act was introduced after widespread concerns about legal highs and their affects on the community. Retailers selling the substances have to get an interim licence from the Psychoactive Substances Regulatory Authority to trade.
Council district living manager Paul Dell said if the council doesn't have something like a zone it will have no influence or say on what the Wellington-based agency (that regulates legal high sellers) will do when they register companies.
