Crash blocks Arthur's Pass
A collision near Arthur's Pass does not appear to be as serious as first thought, police say.
Two rescue helicopters from Christchurch and Greymouth went to the scene of the two-car crash at Klondyke Corner, east of Arthur's Pass village.
But injuries from the crash did not appear to be as serious as first thought, Police communications spokesman Inspector John Doherty said.
"We're still there, hoping to clear the road and get some traffic flowing fairly soon," he said.
NZCC Rescue Helicopter pilot Angus Taylor said he had flown a pregnant woman and her 2-year-old son, who had been involved in the accident, to Greymouth Hospital.
"[The son] had taken a bang to the head, but obviously it wasn't as serious as first thought," he said.
The accident had closed a stretch of State Highway 73, but it was partially reopened by 4:25pm.
The New Zealand Transport Association said one lane had been re-opened, and travellers should expect minor delays.
