Two people captured after a severe collision in North Canterbury have been released.
Emergency services were called for a collision at the intersection of Lineside and Mulcocks roads in Flaxton, just before 6pm on Thursday.
Initially, three vehicles were thought to be involved. However, New Zealand Fire and Ambulance (FENZ) spokeswoman Lyn Crosson said field crews were "talking" about two vehicles, one of which ended up on a nearby railway line.
Crews exterminated two people, one from each vehicle, she said.
Spokeswoman for St. John said two ambulances, an ambulance and a helicopter, were dispatched to the scene.
She said one patient was in critical condition, one was serious and the other was moderate.
All three were taken to Christchurch Hospital.
Crosson said FENZ approached train control to inform them that the rail line was blocked. "They said they would drop off any train until we got back to them and they said the line was clear," Crosson said. Still, she said no train was planned for the near future.
A police spokeswoman said the road was blocked and that there were diversions across Revells Road and State Highway 1.
A police unit for serious accidents has been notified.
