Sometimes public concern does not begin with a scientific paper, a government review, or a media headline.
Sometimes it begins with a parent looking out the window and noticing strips of dead vegetation appearing along a school fence line.
Recently, an Auckland family contacted No More Glyphosate NZ after becoming increasingly concerned about what appeared to be herbicide spraying around the school their daughter attends — a school that also directly borders their property.
According to the family, the issue first caught their attention during the Christmas holidays, when they suspected some form of weedkiller had been used around parts of the school grounds. More recently, they noticed fresh spraying again along the shared boundary fence beside their home.
Wanting clarity, the parent emailed the school directly asking what product had been used and whether it was Roundup, glyphosate, or a similar herbicide.
The response they received was brief: “Yes, it’s similar to Roundup.”
No specific product name was provided.
After looking more closely around the grounds, the family said it appeared spraying had occurred extensively throughout parts of the school property, particularly along fence lines, edges, and boundary areas.
For the family, the concern quickly became larger than a single spray event. Their daughter attends the school, their home directly borders the grounds, and they suddenly realised they did not actually know what was routinely being sprayed around either environment or how often those applications were occurring.
That realisation is becoming increasingly common.
Many Parents Assume Schools Strictly Control Herbicide Use
Most parents probably assume schools operate under very clear nationally consistent rules when it comes to chemical use around children.
There is often an expectation that spraying near schools would involve standard notification processes, carefully defined safeguards, or at least clear public visibility around what products are being used and where.
But once families begin asking direct questions, the situation can appear far less transparent than many people expect.
Practices often vary from one school to another. Some rely only on occasional spot spraying while others use herbicides more routinely as part of grounds maintenance programs. Some schools proactively communicate with parents before spraying takes place, while others treat it as standard operational maintenance requiring little public discussion at all.
Much of this work also happens quietly in the background during school holidays, weekends, or outside normal school hours. In many cases, parents never actually witness the spraying itself. They simply notice the dead vegetation afterwards.
For neighbouring residents living directly beside schools, however, the issue can feel much closer and more personal. Spraying may occur only metres from homes, gardens, pets, washing lines, outdoor play spaces, or open windows.
Concerns that might otherwise feel theoretical can become much more immediate when the spraying is occurring directly beside a family home.
What Does “Similar to Roundup” Actually Mean?
One of the more revealing aspects of the school’s response was not necessarily what it said, but how little it actually clarified.
“Similar to Roundup” sounds straightforward on the surface, yet most members of the public would struggle to know precisely what that means in practical terms.
Many people use the word “Roundup” almost generically to describe weedkiller. But commercial herbicides are not all identical products, even when they contain glyphosate as an active ingredient.
Glyphosate itself is only one component within many herbicide formulations. Products may also contain surfactants and other co-formulants designed to help chemicals spread across plant surfaces, penetrate leaves, or remain stable during application.
Without the exact product name, neighbouring residents and parents often have no practical way of understanding precisely what has been sprayed around homes, schools, parks, or playgrounds.
That lack of visibility is part of what increasingly unsettles many families.
Not because every parent expects to become a toxicologist overnight, but because most people reasonably assume they should at least know what chemicals are being applied around environments used daily by children.
Why These Conversations Are Growing
Over recent months, No More Glyphosate NZ has also received messages from other parents, grandparents, teachers, and neighbouring residents raising similar concerns about herbicide use around schools, playgrounds, sports fields, and public spaces.
In many cases, people only begin paying closer attention after directly witnessing spraying taking place themselves or noticing dead vegetation appearing around areas used daily by children.
Some are simply looking for information. Others are asking whether schools are required to notify parents before spraying occurs, what products are being used, or whether non-chemical alternatives are being considered at all.
What emerges repeatedly is not necessarily panic, but a growing sense that many families assumed these decisions were already operating within far clearer and more transparent systems than may actually exist in practice.
More Parents Are Concerned About Glyphosate Around Schools
Public concern around glyphosate-based herbicides has grown steadily internationally over the past decade, particularly following the International Agency for Research on Cancer’s 2015 classification of glyphosate as “probably carcinogenic to humans.”
At the same time, regulatory agencies in New Zealand and elsewhere continue to maintain that glyphosate can be used safely when applied according to approved directions and exposure limits.
For many ordinary families, the tension between those two positions has become increasingly difficult to ignore.
On one side sit longstanding regulatory approvals and decades of widespread use across agriculture, parks, schools, berms, and public spaces. At the same time, an expanding body of scientific literature continues examining issues such as chronic low-level exposure, endocrine disruption, oxidative stress, microbiome impacts, formulation toxicity, and cumulative environmental exposure patterns.
Few parents are spending their evenings reading toxicology journals. Yet an increasing number are beginning to question whether modern regulatory systems adequately account for repeated, long-term exposure across multiple everyday environments over the course of childhood.
History has repeatedly shown that products once widely accepted as safe can later become the subject of major public health controversy. Asbestos, leaded petrol, 2,4,5-T, PFAS chemicals, and even cigarettes all existed for years within regulatory systems and accepted use practices before broader societal reassessment eventually occurred.
That history does not automatically prove harm is occurring in every situation involving glyphosate-based herbicides.
But it does help explain why many families no longer view “currently approved for use” as the end of the conversation.
The Bigger Questions About Herbicide Exposure Around Children
In many ways, this Auckland family’s experience reflects a much broader shift now taking place quietly across New Zealand communities.
People are beginning to pay closer attention to the environments they move through every day and asking questions they may never have thought to ask before.
- What is being sprayed around schools?
- What is being used around playgrounds, sports fields, drains, berms, and parks?
- How often does this occur?
- Who decides what products are appropriate?
- How much transparency should exist around these decisions when children are involved?
Those are not fringe questions anymore.
And importantly, many families are not demanding certainty or making dramatic claims. In most cases, they are simply asking for clearer communication, greater transparency, and a more precautionary approach around environments used daily by children.
Because for many parents, the issue is no longer just one school, one spray event, or one chemical alone.
It is the growing realisation that modern chemical exposure often occurs quietly, routinely, and cumulatively across multiple ordinary environments most people rarely stop to think about at all.
And once parents begin noticing that reality, it can become very difficult to stop seeing it.
What Parents Can Do If They Have Concerns
For parents who find themselves in similar situations, the most useful first step is often simply asking questions calmly and respectfully.
Many schools may never have received detailed enquiries about herbicide use before, particularly from neighbouring residents or parents concerned about long-term exposure around children’s environments. In some cases, schools may be relying on long-established maintenance practices that have rarely been revisited or publicly discussed.
Where concerns exist, families should ask the school for the exact product name being used, whether Safety Data Sheets are available, and how often spraying occurs around school grounds. Some parents might want to ask whether advance notice could be provided before future spraying takes place, particularly where applications occur near shared residential boundaries, playgrounds, or outdoor activity areas.
Documenting what is observed can also be useful. Photographs or videos of spraying activity, recently treated areas, signage, or affected boundary zones may help establish a clearer timeline of what occurred and where. In many cases, simply being seen while documenting spraying activity may encourage greater care, transparency, and accountability in how these products are used.
Importantly, many parents raising these questions are not demanding certainty or confrontation. They are simply seeking clearer communication and reassurance that precaution is being taken seriously around environments used daily by children.
