Police have confirmed a man and a woman have died following a two-vehicle crash in Southland this afternoon.
Police were called to the accident on the Riverton Wallacetown Highway near Invercargill at 1:30pm.
The crash has occurred at Oreti River Bridge.
The man involved in the crash died at the scene while the woman was transported to Dunedin Hospital in a critical condition before she died a short time later.
