A woman was taken to Whanganui Hospital after a car hit a pole in Aramoho on Sunday night.
St John got a 111 call at 7.14pm, spokeswoman Jess Miller said.
Whanganui's Fire Service also attended, and Senior Station Officer Bryan Coskerie said the car had hit a pole.
The woman was taken to hospital in moderate condition.
It was a rainy evening, and traffic was diverted down George and Gibson streets while emergency services were in action.
