A rally opposing the proposed Trans-Pacific Partnership Agreement (TPPA) will start from the River Traders Market today.
Wanganui, one of 17 centres across New Zealand holding rallies, will hold a dance-march that will begin at the steel ball sculpture by the river at 10.45am.
Speakers will be Mairi Jay and Denise Lockett.
The TPPA is being negotiated by New Zealand and several other Pacific countries, including the United States, Japan and Australia.
Ms Lockett, who describes herself as a run-of-the-mill activist, said concern was growing worldwide over the TPPA, which she said was a corporate-driven pact.
