No More Glyphosate NZ is an independent, community-funded project focused on transparency around glyphosate use, residues, and regulation in New Zealand. We investigate how pesticides, food production, and policy decisions affect public health and consumer clarity — so New Zealanders can make informed choices in a system that often hides the detail.
IARC has rated glyphosate "probably carcinogenic" since 2015 — the same rating given to red meat, talc and night shift work. Three prompted swift regulatory or compensatory action. Glyphosate got a $17 million industry campaign instead, and New Zealand's EPA has never reassessed it.
Canterbury has one of the highest Crohn's disease rates ever recorded anywhere on earth — and cases have nearly tripled since 2006. New Zealand has no dedicated research programme asking whether glyphosate exposure plays a role. This investigation examines the emerging science, the regulatory gaps, and the questions nobody is asking.
When Alan started reacting to certain foods with violent diarrhoea, he had no idea it would lead back to a mystery illness that began in a plastic greenhouse in 1991. Through years of careful observation — including a simple experiment swapping pork for beef — he pieced together a connection to glyphosate that changed the way he eats, shops, and grows his own food.
Seventeen independent scientists classified glyphosate as probably carcinogenic. Over 100,000 people sued. Bayer paid billions. And in New Zealand, you can still buy it next to your groceries — with no warning on the label. The precautionary principle was built to prevent exactly this. So what happened to it?
Two of the world's most authoritative scientific bodies examined the same evidence on glyphosate — and reached opposite conclusions. One decade, US$18 billion in litigation, a court-rejected EPA assessment, and a trade agreement that lets food exceed New Zealand's own residue limits onto our supermarket shelves later, the question of who is actually being protected — and from what — deserves a straight answer.
You can buy glyphosate-based weedkillers at your local New Zealand supermarket. No cancer warning on the label. The EPA says it's safe — but a US court vacated that very finding, Bayer has paid billions to settle lawsuits, and New Zealand's own reassessment was declined. Here's why the chemical stays on the shelf regardless.
Over a million New Zealanders may be living with fatty liver disease without knowing it. Peer-reviewed research is now linking glyphosate — the world's most widely used herbicide — to its rise. Children near agricultural areas are among the most vulnerable. This investigation explores the evidence, the mechanisms, and what New Zealand isn't yet measuring.
On June 25, 2026, the US Supreme Court ruled 7-2 in favour of Monsanto, blocking cancer liability claims from thousands of Roundup users. The ruling cites international regulatory consensus — including New Zealand's. No More Glyphosate NZ asks what that consensus is actually worth, and whether our regulators are paying attention.
A landmark scientific review has confirmed that gut microbes act as gatekeepers of oestrogen metabolism — and that disrupting them may contribute to hormone-driven cancers. No More Glyphosate NZ asks the question the researchers didn't: what role might glyphosate, a patented antimicrobial present in our daily food supply, be playing in that disruption?
Regulatory approvals are snapshots in time — but science never stops moving. As the US Supreme Court's Roundup ruling places chemical safety decisions firmly in regulators' hands, the question becomes: how quickly do those regulators respond when the evidence changes? Canada's new continuous oversight model for glyphosate offers one answer. New Zealand should be asking the same questions.
A US Supreme Court ruling has limited Roundup cancer warning lawsuits against Monsanto. While the decision does not change New Zealand law, it raises important questions about glyphosate regulation, scientific evidence, and public accountability here.
Celiac disease has risen nearly tenfold in New Zealand over three decades. Genetics cannot explain it. But emerging research points to a specific biological mechanism: glyphosate may be depleting the gut bacteria — called Rothia — that break down gluten before it can trigger an immune response. The question is whether anyone in authority is paying attention.
