Regulatory and environmental committee chairwoman Ann Court said the new policies aimed to give the council greater control over where potentially harmful substances could be sold.
"Our intention is to minimise harm to children and young people in particular by ensuring that outlets that sell these potentially harmful products aren't close to schools, churches and similar public facilities."
Ms Court said the council was aware of strong community concern about legal highs, particularly in Kaitaia where there had been protest marches.
The proposed policy would confine legal high outlets to commercial areas.
The council planned to adopt the policy in September so the new controls would be in place before the temporary ban expired.
"We can't legally ban all sales within the district as much as some would want it that way, but we certainly can introduce rules which give a greater level of control over where these sales can happen," she said.
The policies had been developed after consultation with police, Northland's medical officer of health, council staff and community boards. Submissions close on August 1.
"Now is the time for the wider community to tell us whether we've got the proposed changes to the rules right and for retail outlets and licensed premises involved to have their say," Ms Court said.
The Far North had only one outlet licenced to sell legal highs, Jujnovich Holdings on Kaitaia's Commerce St, though the synthetic drugs were reportedly available illegally in Kaikohe. The owner of Jujnovich Holdings, Raymond Jujnovich, voluntarily stopped selling legal highs before the temporary ban came in.
