An Auckland bus driver was pulled out of her bus by three hooded men who punched and kicked her to the ground.
FIRST Union transport organiser Emir Hodzi said the driver was driving her usual night route in Mangere on July 4 when the attack took place.
The woman had since seen her attackers and alerted the bus company to it.
Hodzic said serious driver assaults occurred only a couple of times a year but the incidents highlighted the need to have more robust safety procedures.
A FIRST Union survey in October showed more than half of bus drivers reported being abused or assaulted by passengers while on the job and noted the more minor assaults were often not reported.
