Cape Rodney experiences non-toxic red algal bloom
Auckland Regional Council staff today confirmed the presence of a non-toxic algal bloom at Cape Rodney in the Leigh/Ti
ARC staff were carrying out their monthly routine sample of the area and confirmed the positive result of Noctiluca
scintillens, a non-toxic algal bloom commonly found in the Auckland area in the summer.
"We want to reassure the public the algal bloom is harmless to their health and the environment. Our only advice is for
the boating public not to drive through the bloom as its jelly-like substance may clog engine filters," said ARC Land
and Water Quality Manager Eddie Grogan.
The algae ranges from a light pink to a deep red colour. It looks like pink milk pudding when in concentrated patches
and at night causes phosphorescent waves. Similar blooms have been reported on the North side of Waiheke and at Oneroa
and Palm Beach.
Residents may recall that two years ago Leigh harbour was totally covered by the bloom.
