A new peer-reviewed study found evidence of chromosome damage in human intestinal cells exposed to glyphosate at every concentration tested — including the lowest concentration of 0.01 mg/L. What does that tell us about glyphosate exposure, and what questions remain unanswered?
A new rat study has found glyphosate in amniotic fluid and developmental effects extending across two generations. Researchers also found that male offspring appeared more vulnerable and that a glyphosate-based herbicide generally produced more severe effects than glyphosate alone.
ACC has revealed more about the 10 work-related gradual process claims mentioning glyphosate or Roundup that were all declined. Fewer than four involved cancer and fewer than four involved non-Hodgkin lymphoma. But the crucial question remains: why did none of the claims succeed?
Can you safely compost plants that have been sprayed with glyphosate? Research shows glyphosate can break down substantially during controlled composting — but that isn't quite the same as putting whole sprayed plants into a backyard compost heap. We look at what the evidence tells us, what remains unknown, and why NMGNZ recommends a precautionary approach.
Whangārei District Council supplied detailed information about herbicide use in public spaces, including its product use, Spray Use Policy and an independent 2025 review of glyphosate use and alternatives.
For the first months of life, a breastfed baby may receive almost everything it needs from one source: its mother's milk.
We encourage breastfeeding because...
ACC has identified 10 work-related gradual process claims mentioning glyphosate or Roundup — and all 10 were declined. We examine how ACC assesses long-term occupational chemical exposure, what its own policies say, and the crucial questions ACC has yet to answer.
Masterton District Council identifies the herbicides used in public spaces, where and how often they are applied, contractor requirements, public notification practices, non-chemical controls and its No-Spray Register.
No More Glyphosate NZ's seventh round of independent honey testing found detectable glyphosate in all five retail honey samples analysed by Hill Laboratories. While every product contained measurable residues, all remained below New Zealand's current maximum residue limit, and no AMPA or glufosinate was detected. Repeat testing continues to demonstrate how glyphosate residues can vary between production batches over time.
Central Otago District Council provided detailed information on herbicide use across parks and road reserves, including products used, application schedules, public notification practices, alternative weed management approaches, and confirmation that no formal review of herbicide use has been undertaken in recent years.
Queenstown Lakes District Council has outlined the herbicides used across its public spaces, application practices, notification procedures, operational guidance, and review history in response to an LGOIMA request.
MacKenzie District Council says glyphosate and Grazon are used in selected public spaces under contractor-managed procedures. The council also outlined notification practices, previous alternative weed control trials, and the review of its current maintenance contract.
Invercargill City Council outlined the herbicides used across parks, reserves and sports fields, explained its spraying practices, described alternative weed management methods, and confirmed no formal review of herbicide use has been undertaken in recent years.
Our sixth round of independent glyphosate testing examined five New Zealand honey products purchased from retail outlets. One sample returned a detectable glyphosate result, while the remaining four were below the laboratory reporting limit. This latest round expands one of New Zealand's largest independent datasets on glyphosate residues in retail honey.
Ashburton District Council explains how herbicides are used across parks, roads, reserves and water infrastructure, including operational safeguards, notification procedures, and non-chemical weed management trials.
Waimate District Council confirmed it uses glyphosate-based herbicides in parks, berms, footpaths, cemeteries and other public spaces, with herbicide management guided by operational procedures, contractor requirements and national standards rather than a standalone policy.
Marlborough District Council's LGOIMA response outlines the herbicides used across public spaces, how spraying is managed through maintenance contracts, notification practices, and the council's approach to reviewing herbicide use.
Every food label makes a series of claims, but how do we know they are accurate? We explore why independent laboratory testing plays an important role in verifying what's really in the food we buy.
Stratford District Council outlined the herbicides used in public spaces, non-chemical weed management methods, operational procedures, public notification practices, and measures introduced following its 2020 review.
No More Glyphosate NZ asked Hurunui District Council about herbicide use in public spaces under LGOIMA. Here’s what the council told us about glyphosate use, spraying locations, and treatment frequency.
