A founder of the Maori produce label, Hua Parakore, says iwi food growers and processors are leaders when it comes to indigenous peoples' stand for clean earth and clean food.
Geneva Hildreth said initiatives such as the "pure product" stamp Hua Parakore, Taitokerau Organic Producers (which she also helped found), and Maori plant, environment and cultural sustainability organisation Te Waka Kai Ora had struck a chord among other peoples with similar traditions of earth ethics and spirituality.
"What we're trying to do is promote an indigenous model," Ms Hildreth said of Hua Parakore, the Northland initiative she helped start up in 2012.
It was essentially a process of verification as well as an inherent value system that went beyond the soil and practice-based "organics", she said.
"The process is very deep. People who use this have to be able to talk about the whakapapa of their whenua. It's about how we look at what we're doing, not just meeting standards. There are plenty of standards-based certifications out there.
