Marchers gathered in central Tauranga to say no to genetic modification (GM) and protest against an American GM giant.
Saturday's "March Against Monsanto" was one of many held throughout the country, protesting against the company's sale of seeds engineered to resist insecticides and herbicides, add nutritional benefits or otherwise improve crop yields and increase the global food supply.
Up to 150 protesters crowded Red Square to raise awareness about the issue of genetically modified organisms (GMOs). Volunteers were handing out flyers and holding placards with slogans such as "I'm not a science experiment" and "Say no to GMOs, insecticide, Monsanto".
Local march organiser Martin Stewart said he saw information on Facebook about a "March Against Monsanto" in Christchurch and organised one in Tauranga. He wanted to make people aware of the dangers of GM food and seeds as well as highlighting corruption in places such as the United States and India.
"We were not just marching against the company itself but also looking at trying to get a GMO-free Bay of Plenty eventually. We can start to target and aim for that," he said.
