A 22-year-old man from France has suffered serious leg injuries after jumping from a bridge south of Murchison.
The man was winched from the scene by the Nelson Marlborough Rescue Helicopter and flown to Nelson Hospital.
St John ambulance and the fire service also went to the scene about 1.20pm.
Murchison Volunteer Fire Brigade chief fire officer Paul Wilkins said the man had jumped off O'Sullivan's Bridge with two other friends. The group jumped together but something went wrong when the man hit the water.
It was about a 15-20m drop to the water.
He said the water was still discoloured from recent floods.
''It wasn't a very wise thing to do.''
Mr Wilkins said the man was in a lot of pain and it was difficult to communicate with him due to the language barrier.
The Fire Service took their stretchers to the scene, but it was decided it was easier to winch him out of the area with the helicopter.
''I think they have learnt a valuable lesson.''
