Find out about current and upcoming weed and pest control work.

Effective pest management depends on collaboration. We consult with a range of interested groups when planning control programmes, including neighbouring landowners, district and regional councils, iwi, advocacy groups, and the local community.

Before undertaking any control work, we notify the public by:

  • putting up signs near the affected area
  • publishing notices in local newspapers
  • posting information on this website.

Most of our control work is weather dependent, so advertised dates may change at short notice. We try to avoid carrying out any spraying on weekends or during public holidays.

The tables below provide detailed information about our aquatic weed control work. You can find more information about all our biosecurity programmes in the related content.
