While the Whangarei Marina was full and unable to take on more boats, Marsden Cove Marina already had eight extra boats berth in the last 24 hours with more likely on Sunday.
Bay of Islands Marina, at Opua, had already reached capacity as a result of vessels seeking refuge from the cyclone. "We've accommodated as many as we possibly can," marina manager Chris Galbraith said.

Severe gales and heavy rain were expected in Northland from Sunday evening and into Monday, she said. It is possible rainfall would exceed warning criteria which means more than 80mm in 18 hours.
