Watch: Man's mad dash to narrowly avoid runaway bus on Auckland's North Shore

Astonishing CCTV footage has been released of the moment a man narrowly avoids being hit by a bus before it ploughs into a cafe on Auckland's North Shore.

The incident happened on Birkenhead Ave on October 12, with the CCTV footage being released to 1 NEWS today.

The video shows a man jumping up from a bench he was sitting on and dashing away to safety, from the oncoming bus. 

Inspector Kai Shao has told 1 NEWS at the scene he understands the bus was stationary and picking up some passengers at a nearby bus stop, when for some reason it accelerated.

A father and his two children were also on the pedestrian crossing and the man realised the bus was coming, "so he pushed his children away," Inspector Shao said.

"And the children were not injured and the father was struck somewhere by the bus, and with very minor injury," he said.

Police said in a statement that two children were taken to Starship Hospital as a precaution and an adult male was transported to North Shore Hospital with moderate injuries.
