Auckland might hold the key to whether Northland councils make district plan changes that could see GMOs banned in the region before the end of this year.
The Far North and Whangarei District Councils have decided to investigate plan changes enabling them to regulate the use of GMOs - but are waiting to see if similar proposed changes to Auckland's plan get the go-ahead first.
The possibility of an entire Genetic Engineering-free block from South Auckland to Cape Reinga is closer with the Auckland Council's proposed unitary authority plan.
That move would mean cost-sharing as well as consistency between the Northland and Auckland councils, already partners in the Inter-Council Working Party on GMOs.
If Auckland takes the unitary lead, GE free provisions would apply to its huge landmass and coastal (aquaculture) environs.
