A man jumped from the Bridge St bridge in Hamilton this morning.

Witnesses said the man jumped from about a third of the way across the bridge. It is believed two men jumped in after him.

They reported seeing the first man treading water before the second man pulled him to shore on the Waikato River's east bank.

A Hamilton News reporter on the scene said the rescuer had got the man up onto a pier just north of the bridge, and police and ambulance were on the scene.

St John's Central Region spokesman Mark Tregoweth said they received the call at 8.40am and arrived on scene at 8.46am.

The jumper was taken to Waikato Hospital with moderate injuries. He is now in stable condition. Mr Tregoweth said the man was lucky his injuries were not worse.

"He has moderate injuries, which is surprising really considering the height of the bridge," he said.

Waikato District Command spokesman Senior Sergeant Aaron Alderton said the man had been carried through Memorial Park to the road to get him to the ambulance.

Waikato Police communications manager Andrew McAlley said emergency services were on the scene. He said the rescuer was in good condition and the first man had been carried out through the park to be taken to hospital.
