Red sea mystery off Hawke's Bay coast

The Hawke's Bay Regional Council is taking tests and awaiting results from a likely algal bloom spreading across the sea off the Hawke's Bay coast. Coastwatchers say the reddish-brown discolouration has been growing over several weeks – visitors to the Bluff Hill lookout reported what may have been its early signs on January 31, when it appeared to be coming from a ship apparently circling at sea off the Port of Napier.
