New Zealand Weeds 

This site is dedicated to informing people about weeds in New Zealand. It has been designed both for members of the public and for students looking for information on weeds.

With over 2000 weeds in New Zealand, we do not cover all species, but you will find many of the weeds that commonly cause problems in our pastures, crops, lawns and gardens.

Each page has information on how to identify the featured weed (with photos) as well as information about the weed and some suggestions on how best to control it.

A 3-day short course on Understanding Herbicides is available at Massey University for members of the public wanting to learn how to control weeds using herbicides. There is also a university distance course available on Controlling Weeds. Click here for more information.

This resource has been created, and is maintained, by Dr Kerry Harrington.
