An ambulance officer has been taken to hospital after being punched by a patient they were caring for.
He was one of two ambulance officers, a man and a woman, who were assaulted while attending a routine callout to New Brighton in Christchurch about 7pm tonight.
"It was totally unprovoked," St John Canterbury operations manager Dion Rosario said.
Ambulance staff were treating a patient when the person receiving care assaulted them.
"There was no indication to the staff where this was going."
