No More Glyphosate NZ
334 POSTS0 COMMENTS
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.
Roundup Cancer Lawsuits: What Monsanto v. Durnell Means for You
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.
Glyphosate and Parkinson’s Disease: Is New Zealand Asking the Right Questions?
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.
Glyphosate Safety and Flawed Animal Studies: What NZ Regulators Aren’t Telling You
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.
Potato Testing: Why We Focused on Glyphosate Rather Than Hundreds of Other Chemicals
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.

Glyphosate, Children’s Health, and the Questions Regulators Aren’t Asking
