Investigations are continuing this morning into several crashes yesterday afternoon and last night.

One man faces careless driving charges after his car crossed the centre line in the Milford Sound, hitting another car and injuring two female occupants.

Rain, speed and inattention are believed to have been factors in the crash.

One person was injured at an Auckland railway crossing crash in Henderson, and a woman was killed and another man was seriously injured when a car left the road in Central Otago.
