Not quite a storm off New Zealand, but someone I knew had a fascinating but earie story. He was on a Ship called the Norfolk off Hastings in the 1930's when the big earthquake occured. The previous ship of the same name, an old sailing vessel, had sunk in that area. During the earthquake, in the dark, the wreck rose up just beside them, and they could read the name and recognize the rigging. The crew were very quiet for a while after that!
