Public notice: Spraying operations November 2022 to May 2023

Monday 24 October 2022

This activity is carried out to keep the drains in land drainage schemes free from grass and weed build-up to maintain free flowing capacity in the drainage network.

Otago Regional Council schedules drains in: 

  • East and West Taieri 
  • Tokomairiro 
  • Lower Clutha 

The land drainage schemes ensure that the rural and some urban areas remain productive and liveable.  

Work will be carried out by ORC staff and external contractors between November 2022 to May 2023.
