The incident was at the Clarence St and Blenheim Rd intersection outside a car wash business, about 5.40pm.
Two cars had stopped at red lights on Clarence St when a man got out of his vehicle and attacked the victim who was inside a red car.
The offender then fled north on Clarence St towards Riccarton Rd.
Police investigating the attack do not believe the people knew each other.
