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.
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.

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.
