The Environmental Protection Authority (EPA) is calling for information on the use of the herbicide glyphosate in New Zealand.
This weed killer has been used by home gardeners, farmers, and councils in New Zealand since the 1970s. Although it is commonly known as the active ingredient in Roundup, there are 89 mixtures containing glyphosate that are approved for use in this country.
We are seeking information from New Zealanders – including industry and the general public – about the manufacture, importation, and patterns of use of glyphosate in this country, as well as information on the availability of alternatives, and any impacts on Māori.
Busting the myths about hydration

The warmer weather and longer days have inspired reminders to “stay hydrated” and drink eight glasses of water – or about two liters – a day.
Not to burst anyone’s water bottle, but healthy people can actually die from drinking too much water. I am an exercise physiologist, and my research focuses on overhydration and how drinking too much water affects the body. Since water – and sodium – balance is essential to life, it is extremely rare for people to die from drinking too much – or too little – fluid. In most cases, your body’s finely tuned molecular processes are unconsciously taking care of you.

In 2015, the active ingredient found in Roundup – glyphosate – was classified as being probably carcinogenic to humans by the International Agency for Research on Cancer. (File photo) While approved for use in the EU, European Chemicals Agency (ECHA) and the European Food Safety Authority (EFSA) are currently reviewing the classification and approval of glyphosate. Their conclusions are expected to be released in mid-2022. EPA general manager of hazardous substances and new organisms, Dr Chris Hill, said by calling for information on the chemical’s use now, the authority would be better prepared to assess the EU findings. There has been ongoing public debate about the effects of glyphosate on environmental and human health.
