Every year Waikato Regional Council carries out targeted spray operations to control invasive pest plants growing in our rivers, lakes and wetlands.
This work is important to protect the environment – and in particular agricultural production – from the impacts of these pest plants, as well as to improve biodiversity.
Resource consent 124871
Waikato Regional Council holds a resource consent (124871) to carry out this work. The consent authorises:
- the application of agrichemicals to air where they may enter water and the coastal marine area within the Waikato region, and
- the use of specific herbicides for controlling pest plants that cannot generally be controlled with glyphosate.
Public notice - spraying operations
Waikato Regional Council advises that under Resource Consent 124871 spraying of pest plants growing in aquatic and semi-aquatic locations will continue over the next three months.
You can read the public notice below. For specific details of when, where and what we are spraying, please check the scheduled operations information on this webpage.
Where and when are we spraying?
Where are we spraying?
You can access and view our map of operational areas using the link above.
- Operational areas are shown on the map with purple shading.
- Use the Search bar in the top left-hand corner to search for your address and see where spraying is happening in relation to your property.
When are we spraying?
Application may occur at any time during daylight hours, providing weather and tide conditions are suitable.
As these pest plants are difficult to control, two to three follow-up applications may occur over the next 12 months. It is unlikely that spraying will occur during duck shooting season. There will be no spraying on public holidays.
For more details, see the list of scheduled spraying operations on this page.
