Waiau township stopbank remediation and construction

Waiau township has been subject to many flood events from both the Mason and Waiau Uwha Rivers.

Numerous ad-hoc stopbanks were constructed over the past century, the earliest dating between 1907 and 1922 by the Waiau Riverside Protection Board.

Completed work

Completed in February 2022, this project improved the level of flood protection to Waiau through the remediation and strengthening of two existing stopbanks on Inland Road, and construction of a new stopbank, including topsoiling and fencing, which borders the eastern side of the town.
