Glyphosate: Call for information

We are calling for information on the use of the weed killer glyphosate in Aotearoa New Zealand. This request for information is the very first step in deciding whether to change the rules around its use.

About glyphosate

  • A weed killer used in New Zealand since the 1970s.
  • It is common and is the active ingredient in many consumer and agricultural products.
  • Used by home gardeners, farmers, and councils.
  • It is safe to use if you follow the instructions and the rules.

Information we are looking for

We want to find out from importers, manufacturers, professional users, retailers, organisations, community groups and the public:

  • information that is relevant to the current use, practices, and benefits of glyphosate products
  • evidence of the effects of glyphosate products: positive or adverse impacts; toxicology; ecotoxicology; environmental fate studies; or monitoring results
  • how glyphosate products are used and applied in different areas, for example, agricultural, domestic, in public areas, for conservation, or as an aquatic herbicide
  • your views on the positive or negative impacts you think glyphosate products have on our environmental, economic, social and cultural wellbeing.

Why we are asking you

  • There is ongoing public debate about the effects of glyphosate on the environment and people’s health.
  • Glyphosate is currently approved for use in the European Union until 15 December 2022. That approval is now being reviewed, with a decision due mid-2022.
  • The information you provide in this call for information will be used to assess whether there are grounds to reassess the use of glyphosate in New Zealand.

It’s a first step

  • This call for information is the very first step in understanding how glyphosate is currently used in New Zealand.
  • If there are grounds to reassess glyphosate and a formal reassessment application is made, you will have an opportunity to make submissions on the application once it has been publicly notified.
