James Henry Coakley, 68, was allegedly involved in the maintenance of the bus carrying a tour party of 31 Chinese tourists when it lost control and collided with a car travelling up Otira Gorge in Arthur's Pass on December 31, last year.

It overturned and slid into roadside barriers, which stopped it from plunging into a ravine.
Coakley, of Ohoka, 25kms north of Christchurch, was charged with injuring by unlawful act.

The car passengers - a visiting Swiss family of three - also sustained moderate to serious injuries, police said.

All of those injured in the crash have since returned home.
