Health warnings have been issued at dozens of Auckland beaches due to concerns about wastewater overflow and poor water quality following today's torrential downpours.
An alert system on Auckland Council's Safeswim website warned wastewater overflow had been detected by sensors at all of the central beaches and said swimming was "not advised".
The warning was in place for Mission Bay Beach, Browns Bay, Castor Bay, Herne Bay, Mairangi Bay, Narrow Neck, Okahu Bay, Point England and St Mary's Bay.
