A large charter boat is being battered on rocks off the shore of the Mauao base track.
The boat was aground on rocks about 11.35pm last night and as the tide has changed this morning, the boat has begun breaking apart as waves crashed into it.
A member of the public walking the Mauao base track said there was a large amount of debris in the water and the boat continued to smash against the rocks with every new wave.
A large crowd has gathered on the track, stopping to watch and take photos. Other boats are floating nearby, with people in one dinghy trying to scoop up debris with a net.
