A mountain biker caught on camera in an apparent case of "bike rage" has been defended by a fellow track user after video of the incident prompted a storm of criticism.
Video footage from cyclist Jordan Brizzell's helmet mounted-camera shows another cyclist he was following - and attempting to pass - on the Flying Nun track on Christchurch's Port Hills confronting and appearing to push Mr Brizzell.
The cyclist has not been identified.
Bruce White, who met the unidentified cyclist while walking in the Port Hills with his wife on the day of the incident, said he felt it would be a waste of police time.
