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.
Bayer has paid nearly $20 billion settling Roundup cancer claims. More than 100,000 lawsuits have been filed. Now, with the US Supreme Court, the Trump White House, and state legislatures all moving to shield the company from liability, the question is no longer just about glyphosate. It's about who the system is built to protect.
New Zealand has 14,000 people living with Parkinson's disease — a number heading to 20,000 by 2040. France, Germany, and Italy have already recognised it as an occupational disease linked to pesticide exposure. New Zealand has no research programme, no recognition, and no plan. That needs to change.
When MPI and the EPA tell us glyphosate is safe, they are relying on animal studies conducted on laboratory rats and mice whose biology has been profoundly distorted by decades of commercial breeding. The science of 'safe' is more fragile than regulators want you to know.
After publishing our potato testing results, many readers asked why we only tested for glyphosate, AMPA and glufosinate. The answer reveals just how many chemicals can be used in modern agriculture—and why comprehensive pesticide testing is far more complex and expensive than many people realise.
As part of the No More Glyphosate NZ Council Herbicide Transparency Project, Taupō District Council provided details of herbicide use across public spaces, including glyphosate application locations, thermal weed-control methods, and its current Weed Management Policy. The council also confirmed that the policy, adopted in 2009, has not been formally reviewed since its adoption.
As part of the No More Glyphosate NZ Council Herbicide Transparency Project, we asked Buller District Council about herbicide use in public spaces. The council provided details on products used, spraying locations, notification practices, contractor procedures, record-keeping, and plans for future agrichemical review.
As part of the No More Glyphosate NZ Council Herbicide Transparency Project, we asked Upper Hutt City Council about herbicide use in public spaces. Here's what the council disclosed about products used, spraying locations, frequencies, and oversight arrangements.
As part of the No More Glyphosate NZ Council Herbicide Transparency Project, we examined Clutha District Council's use of glyphosate in public spaces, spraying practices, notification procedures, and contractor requirements.
After 45 years in paediatrics, Dr Michelle Perro believes glyphosate exposure deserves far greater scrutiny. In this interview, she discusses children's health, gut disorders, environmental exposures, and the questions she believes regulators are overlooking.
As part of the No More Glyphosate NZ Council Herbicide Transparency Project, we asked Dunedin City Council about herbicide use in public spaces. The council provided detailed information covering glyphosate use, spraying locations, notification practices, alternative methods, and a recent review of weed-control policies.
As part of the No More Glyphosate NZ Council Transparency Project, we examined Tauranga City Council's herbicide policies, spraying practices, notification systems, and six years of agrichemical-use records.
We tested three potato varieties purchased from Woolworths New Zealand for glyphosate residues. All three returned non-detect results. Here's what that means—and what it doesn't.
Canada now continuously monitors new glyphosate evidence as it emerges. Should New Zealand adopt a similar approach, or is periodic reassessment enough in a rapidly evolving scientific landscape?
