Do you know when chemical spraying is planned in your local parks, reserves, roadsides or waterways?
Check the Latest Public Spraying Notices
VIEW PUBLIC SPRAYING NOTICES — 2026
Find announced spraying locations, scheduled dates, chemicals identified and links to original council notices.
Monitoring began in November 2026. The 2026 register is not a complete record of spraying announcements for the entire year.
Across New Zealand, councils and other public agencies regularly use herbicides, pesticides and plant growth regulators to manage weeds, vegetation and public spaces.
Some publish detailed spraying schedules identifying the locations, dates and chemicals involved. Others provide only general notices, broad application periods or limited information about the products being used.
And unless residents know where to look, these announcements can be surprisingly easy to miss.
No More Glyphosate NZ (NMGNZ) is doing its best to find and share publicly available spraying notices from councils and other public agencies across New Zealand.
We’re a small, community-funded organisation, and finding these announcements isn’t always straightforward. Notices can be scattered across council websites, buried in downloadable documents, posted on social media or published in places that are difficult to discover.
We cannot possibly find, record or publish every spraying notice. But by bringing together those we do find, we hope to make it easier for people to know what’s being planned in their communities.
And with your help, we may be able to find considerably more.
What Spraying Notices Do We Monitor?
We look for publicly available spraying announcements from councils and other public agencies throughout New Zealand, with particular attention to chemical applications in places used by the public.
These include:
- Parks, reserves and recreational areas
- Sportsgrounds and areas surrounding playgrounds
- Footpaths, roadsides, cycleways and walking tracks
- Streams, rivers, lakes, drains and other waterways
- Public gardens, cemeteries and council-managed land
Our current listings identify scheduled spraying dates or application periods, locations, products and active ingredients where disclosed, and links to the original announcements.
Important: A published spraying schedule does not necessarily mean an application has taken place. Spraying may be delayed, cancelled or rescheduled because of weather, operational requirements or other circumstances.
What Information Do We Record?
Where the information is publicly available, our spraying-notice records include:
- Council or public agency: The organisation responsible for the announced programme.
- Location: The streets, parks, reserves, waterways or other areas identified.
- Notice date: When the spraying announcement was published, where this can be established.
- Scheduled application dates: The proposed spraying date or period.
- Products and active ingredients: The chemicals identified in the notice.
- Public safety information: Any stated precautions, access restrictions, signage or re-entry requirements.
- Original source: A link to the council or agency announcement.
Not every notice contains all this information.
Where details are missing, we aim to identify those gaps rather than assume information that has not been disclosed.
Why Are We Doing This?
Public spaces are shared by families, children, walkers, cyclists, sports participants, pet owners and others who may be unaware that chemical spraying is planned in areas they regularly use.
People should be able to find out what chemicals are scheduled for use, where applications are planned and whether any precautions are recommended.
Yet this information is often scattered across council websites, public notices, downloadable schedules and social media announcements.
Some notices provide very little advance warning before spraying is scheduled to begin. Others describe application periods extending over weeks or months, making it difficult for residents to know when a particular location might be treated.
By bringing these announcements together, we hope to make the information more accessible and encourage greater transparency about chemical use in public spaces.
Being informed should not depend on knowing which council webpage to check.
More Than Just Spraying Alerts
This initiative also forms part of NMGNZ’s wider work examining herbicide use and public accountability across New Zealand.
Through our Council Herbicide Transparency Project, we have been asking councils which herbicides they use, where and how frequently they apply them, what policies govern their use and when those practices were last reviewed.
The Public Spraying Alerts initiative complements that investigation by examining what councils and other agencies announce publicly about planned chemical applications.
Over time, retaining these notices may help us identify patterns in how spraying is communicated, including whether councils consistently disclose the chemicals being used, provide meaningful advance warning and explain precautions for people using affected areas.
These records may also help identify differences between councils and opportunities to improve public notification practices.
Public Spraying Notice Archive
We intend to retain historical notices rather than remove them once their scheduled application periods have passed.
This will allow readers to look back at what spraying was announced, where it was planned and what information was made publicly available at the time.
Annual records
- 2026 — Public Spraying Notices (Monitoring commenced November 2026)
As the collection grows, annual records may be organised into monthly sections to make them easier to navigate.
Our archive documents publicly announced spraying programmes. It should not be interpreted as a verified record of all chemical applications actually undertaken.
Have You Seen a Spraying Notice We’ve Missed?
This is where you can help.
Despite our best efforts, we know there will be spraying announcements we don’t find. Some may appear only on local Facebook pages, community noticeboards or council websites that are difficult to navigate.
If you come across a notice about planned chemical spraying in a public area, please let us know — either through our Facebook page or by email.
A link to the original announcement is ideal, but a screenshot or details of the council, location and spraying dates would also be helpful.
You can contact us through:
- Facebook: No More Glyphosate NZ
- Email: Our contact page
We can’t promise to publish every notice we receive, but every contribution helps us build a clearer picture of what’s happening around the country.
The more eyes we have looking, the more useful this resource can become for everyone.
Important Information About These Notices
No More Glyphosate NZ is an independent, community-funded organisation. We are not affiliated with the councils or public agencies whose notices appear in our records.
This is a best-efforts public-information initiative, not a comprehensive or official national spraying register. We cannot guarantee that every spraying announcement will be found, that every planned application will be recorded, or that all published details will remain current.
The absence of a council, location or spraying notice from our records does not mean that spraying has not been planned or carried out there.
Information is gathered from publicly available sources and is provided for general public awareness.
Spraying schedules can change without notice. A date range may represent a period during which spraying could occur, rather than a confirmed date for a particular location.
The inclusion of a product in a spraying notice does not necessarily establish that it was applied, or that every listed product was used at every location.
For the most current information, including access restrictions and safety precautions, readers should consult the original council or agency notice and contact the responsible organisation directly where necessary.
We aim to present the information accurately, distinguish confirmed details from information that has not been disclosed, and correct errors when they are identified.

The feature image on this page was created using AI-assisted image generation from an original concept developed by No More Glyphosate NZ and refined for publication in Canva. It is an illustrative representation, not a photograph of an actual spraying operation.
We recognise that AI technology has an environmental footprint. However, as a small, community-funded organisation working with limited resources, we must make practical choices about how best to use the time and funding available to us.
Our priority is to direct those resources towards independent testing, research and public information. AI-assisted imagery is one of the tools that helps us communicate our findings without diverting funds from that work.
