The sale of synthetic drugs could be banned in poor suburbs such as Otara, Mangere and Henderson and small residential shopping centres under a policy being developed by Auckland Council.
The council is drawing up rules where retail outlets of psychoactive substances can operate, including a ban within 300m of a high school, 100m of a primary school and 500m of an existing store.
It is hoped the rules will be in place by the time synthetic drugs are due back on sale next year.
The Government made an emergency law change in May stopping the sale of all party pills and synthetic cannabis until a rigorous testing regime is in place.
Under the Psychoactive Substances Act 2013, councils can produce a "local approved product policy" to regulate where legal highs can be sold.
