Find out how to safely use glyphosate, what it is used for, and how it is regulated in New Zealand and overseas.
Glyphosate is a chemical used to control weeds. Glyphosate-based substances are perhaps the most common herbicides used in New Zealand and around the world.
It is safe to use, as long as people follow the instructions on the labels of products containing glyphosate.
The use of glyphosate in New Zealand
Glyphosate has been used in New Zealand since the 1970s. It is sold under different brand names, including Roundup.
It is used by commercial businesses, councils, and around the home. Some of the places it is used include orchards, vineyards, pastures, vegetable patches, roadways, parks, and sports grounds. It is used in the garden at home.
Glyphosate is regulated in New Zealand and there are laws around its use. Products containing glyphosate are considered safe, provided that people follow the rules. These include:
- wearing personal protective equipment, such as gloves, goggles and boots
- using sprays in calm and dry conditions
- storing and disposing of products correctly.
We, the EPA, actively monitor and review the status of glyphosate using information we gather from credible sources. This includes reviews and decisions made by international regulators and research groups. As well as New Zealand, other countries regulate the use of glyphosate.
