As part of the No More Glyphosate NZ Council Herbicide Transparency Project, we asked councils across New Zealand about herbicide use in public spaces, the products being used, the policies governing their use, and whether these practices have been reviewed in recent years.
Kapiti Coast District Council provided a detailed response, including information about where herbicides are used, application frequency, the regulatory framework guiding herbicide use, and a chemical inventory listing products held by the council.

What We Learned
Kapiti Coast District Council confirmed that herbicides are used across a range of public spaces, including parks, reserves, road reserves, footpaths, sports fields, tracks, trails, and ecological restoration sites.
The council explained that application frequency varies depending on the location and purpose of the treatment. Some programmes operate on scheduled seasonal cycles, while others occur throughout the year in response to weed growth and management requirements.
The response also included a chemical inventory showing that the council maintains a broad range of herbicides, alongside fungicides, insecticides, rodenticides, and other pest-management products.
The inventory supplied by the council is one of the more extensive received through the Council Herbicide Transparency Project to date, reflecting the wide range of vegetation, pest, and environmental management activities undertaken across council-managed land.
Where Herbicides Are Used
The council advised that herbicides may be applied in:
- Parks and reserves
- Road reserves
- Footpaths
- Sports fields
- Tracks and trails
- Ecological restoration sites
The frequency of spraying depends on the type of site and the weeds being targeted.
For example, track and trail edges are typically sprayed twice each year during spring and autumn. Sports fields may also receive prickly-weed treatments twice annually, although some autumn applications occur only where required.
Roadside pampas control is generally undertaken once per year, while ecological restoration sites may receive herbicide treatments throughout the year depending on weed presence and growth stage.
Products Identified
Kapiti Coast District Council supplied a chemical inventory containing more than 60 products.
The inventory includes glyphosate-based herbicides and a range of other herbicide products commonly associated with active ingredients such as dicamba, MCPA, picloram, amitrole, glufosinate, fluroxypyr and haloxyfop.
Products listed included:
- Knock Out 360
- Terminate Herbicide
- Activated Amitrole
- Dicamba 500
- Banvine Herbicide
- MCPA 750
- Starane Xtra
- Liberty 200SL Herbicide
- Gallant Ultra
- Fusilade Forte
- Cut’n’Paste Picloram Gel
- Cut’n’Paste MetGel
The inventory also included a range of fungicides, insecticides, rodenticides, adjuvants and other pest-management products used across council operations.
Policies and Reviews
Kapiti Coast District Council advised that herbicide use is guided by:
- Greater Wellington’s Natural Resources Plan for the Wellington Region
- Hazardous Substances and New Organisms Act 1996 (HSNO)
- Health and Safety at Work (Hazardous Substances) Regulations 2017
When asked when the current approach to herbicide use was last formally reviewed, the council referred to the development of Greater Wellington’s 2023 Natural Resources Plan.
However, the response did not identify a specific date when Kapiti Coast District Council itself last formally reviewed its herbicide-use programme or vegetation-management practices.
Documents Provided
The council supplied:
- Application location information
- Application frequency information
- Policy and regulatory references
- Chemical shed inventory
Why This Matters
Across New Zealand, councils manage thousands of hectares of parks, reserves, sports fields, roadsides, tracks, and other public spaces.
Understanding what products are being used, where they are applied, and what policies guide their use helps communities make informed decisions and contributes to greater transparency around public-space weed management.
The Council Herbicide Transparency Project aims to build a nationwide public record of how herbicides are managed across New Zealand’s local authorities, allowing residents to better understand practices in their own communities.
