"Under the TPPA, transnational corporations will be able to dictate changes to New Zealand laws," Napier Grey Power representative and Napier City Council member Maxine Boag said. "It represents one of the greatest threats to New Zealand sovereignty, and it is being negotiated in secrecy."
The Hawke's Bay event was launched with speeches from representatives of community organisations, workplaces, unions and political parties at 12.15pm and finished at about 2pm with a waiata.
Ms Boag described the day as "peaceful and pleasant" despite the passionate topic of conversation. "There are no benefits for workers or farmers that we can see.
"It's all about big corporations."
On Wednesday March 25 Napier City Council's regulatory standing committee will consider a recommendation to adopt a 12-point resolution that expresses concern about the TPPA.
So far the resolution had been adopted by city councils in Auckland, Christchurch, Dunedin, Nelson, Tasman and Wellington.
