A group campaigning for the removal of GST from food plans to defy Whangarei District Council and use a city mall to display its petition.
The Residents' Action Movement is holding what it calls a people's procession to Parliament and its convoy expects to arrive in Whangarei about midday on Tuesday.
The council has refused to let the group use the Cameron Street mall for its campaign, which it regards as a political event.
But Vaughan Gunson, organiser of the procession, says the GST campaign is not party-political and the council's decision is ridiculous.
Nevertheless, the council says the group could be liable for a hefty fine if it goes ahead with its plans.
