New Zealand weeds database

Find information on 77 of the more troublesome weeds found in New Zealand agriculture and horticulture.

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.

This database provides information on 77 of the more troublesome weeds found in New Zealand agriculture and horticulture. 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.
