Canterbury DHB’s Community and Public Health unit has lifted its algal bloom health warnings for the Selwyn/Waikirikiri River at Coes Ford issued on 25 January 2021 and Cust Main Drain at Skewbridge issued on 10 May 2021.

Canterbury Medical Officer of Health Dr Ramon Pink says Environment Canterbury’s monitoring of these two sites will resume next summer when there is increased likelihood of cyanobacteria growth.
