The grounded container ship Rena broke-in-two after a strong storm struck during the New Years weekend.  The storm with 15 foot swells battered against the hull causing the vessel to split apart some 1.5 meters wide.   Divers have not been able to investigate to see if the Rena’s hull is still connected under the surface.   Both sections remained firmly aground, but oil that was trapped in the hull has leaked out.   Reports state a light oil sheen has been spotted and has come ashore.   Debris from containers that have fallen overboard has washed ashore near Tauranga and along the shores of Motiti Island.
