Hurunui District Council Herbicide Use and Public Space Spraying

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 those practices have been formally reviewed.

Hurunui District Council initially advised that responding to the full request would require an estimated three to four hours of staff time and that charges (at $135/hour) could apply beyond the first hour in accordance with the council’s LGOIMA charging policy.

Following a refinement of the request, the council provided information about the herbicide product used, where it is applied, and the general frequency of treatment.

Quick Summary

What We Learned

Hurunui District Council advised that it currently uses Glyphosate 360 for weed control in publicly accessible council-managed spaces.

The council stated that herbicide applications occur within parks, playgrounds, berms, footpaths, and reserves.

When asked about treatment frequency, the council advised that spraying is dependent on weed growth, with approximately two treatment cycles undertaken each year.

No additional information was supplied regarding operational policies, notification procedures, review processes, alternative weed-control methods, or supporting documentation.

Application Locations and Frequency

Hurunui District Council advised that Glyphosate 360 is used in parks, playgrounds, berms, footpaths and reserves.

The council stated that treatment is dependent on weed growth, with approximately two spraying cycles undertaken each year.

No further information was provided regarding prioritisation, seasonal scheduling or location-specific programmes.

Products Identified

Note: Active ingredients have been identified from publicly available product information where they were not explicitly stated in the council’s response.

Documents Provided

No supporting documents were provided with the council’s response.

Observations

Hurunui District Council provided one of the briefest responses received as part of the Council Transparency Project. While the refined request answered the three questions ultimately asked, no additional documentation accompanied the response.

The council was also the first—and, at the time of publication, the only council—in the project to advise that charges could apply for responding to the original request before it was refined.

Following refinement of the request, the council’s response consisted of three brief statements identifying the product used, the locations where it is applied, and the general frequency of treatment.

No policy documents, review information, notification procedures, operational guidance or supporting records were provided.

Other councils participating in the project have supplied responses ranging from several pages to extensive document sets.

Why This Matters

Councils manage a wide range of public spaces on behalf of their communities. Understanding what products are being used, where they are applied, and how decisions are made helps contribute to greater transparency around weed management in public areas.

The Council Transparency Project aims to build a nationwide public record of herbicide management practices across New Zealand local authorities so residents can better understand what is happening in their own communities.
