"We don't care about rain and hail, TPPA will not prevail," rallygoers chanted on Saturday as they marched to Majestic Square.
About 200 people braved the unpredictable weather to join the anti-Trans-Pacific Partnership Agreement (TPPA) march and rally, organiser Denise Lockett said.
She and co-organiser Chris Cooper arranged speakers such as Te Oranganui Iwi Health Authority's Nancy Tuaine, Phil Rewiti, Nelson Lebo, Deputy Mayor Hamish McDouall, and David Hughes to address the public and gathered members of TPPA Action Whanganui on the controversial trade deal.
The details of the deal, involving 12 countries, including New Zealand and the United States, have been kept behind closed doors.
"It went from sunshine to rain to hail. They marched in the hail, the dear, sweet people," Ms Lockett said.
