Northland Regional Council, on the other hand, has resisted pressure to include strong GMO precautions in its long-term plans because that council says central Government has the risks covered.
Last week's unanimous decision was the result of 10 years of effort between councils and the community, and inter-council cooperation, Ms Deeming said.
"We have maximised our joint resources to assess risk in a systematic way and decide how to address them in a way that is workable."
She paid tribute to the council's Futures Planning team leader Dr Kerry Grundy, who convened the inter-council working group and provided research and guidance on which the ground-breaking decision was based. Dr Grundy said the collaborative approach had been a cautious yet responsible way to proceed with a contentious and complex issue.
The plan change cannot be actioned until a public process involving consultation, submissions and hearings.
Zelka Grammer, from GE Free Northland, said applications for any field trials in Northland would now face significant deterrents in that additional tier of protection imposed by local councils.
Far North District Council will be the next Northland council to vote on the recommendations.
