Cr Keith Price, a former drugs squad detective, said the council had to make it as hard as possible for anyone to sell the substances anywhere.
Cr Maxine Boag, who had helped lead the group Tu Tangata Maraenui in a campaign against the suburban sales, said: "These substances shouldn't be allowed to be sold at all".
The move seeks to control the sale and distribution of the substances, commonly known as legal highs or synthetic cannabis, or such trade names as Kronic and K2, but the mayor and the 12 at her table were clear they didn't want the substances in their community at all.
A copy of the draft, along with a view of the restricted zone, is available at the website www.napier.govt.nz, and the mayor urged councillors and the public to make sure everyone's views were heard.
Cr Mark Herbert spoke emotionally of wanting the substances out of Napier, referring to his experience of witnessing a person's battle with P and regarding the legalised substances as every bit as bad.
His colleague, Cr Michelle Pyke told the council shortly before coming to the meeting she'd been involved in having a person taken into mental health care because of the effects of the substance abuse.
The draft was adopted by the Napier City Council yesterday, and public submissions are open until October 28.
