It is possible that some of the wrecks were caused by the St. George Lighthouse being in the wrong location. The light was removed and relocated to the Crookhaven Head lighthouse. The stone tower was subsequently demolished by the New Zealand Navy which used it for gunnery practice, it had to be removed lest it be confused with the then newly established light on Point Perpendicular.
