Fifteen people were on board the bus at the time, but only one was injured.
A police spokeswoman said they responded to a report of a single-vehicle crash on the Chatto Creek-Springvale Rd (State Highway 8) about 9.40am yesterday, after a bus hit the pole.
A commercial vehicle team travelled from Dunedin to investigate the cause of the crash, she said.
The road was closed for a period but reopened under stop/go traffic management and a restricted 30kmh speed limit.
Aurora Energy reported power was out to 310 customers in the Chatto Creek, Galloway, Letts Gully, Springvale and Waikerikeri areas.
A spokeswoman for the company said power had been restored to the majority of customers yesterday afternoon.
A reporter at the scene said the crash happened in icy conditions.
Sergeant Adam Elder, of Alexandra, said at the scene that the vehicle was heading towards Omakau and had ‘‘just lost it on the road in the ice’’ and had taken a power pole out.
Inquiries were continuing. Sgt Elder believed the road conditions may have contributed to the crash.
A Hato Hone St John spokesman said two ambulances and two rapid response vehicles attended the scene.
Of the 15 people on the bus, 14 were uninjured and one patient was transported to Dunstan Hospital in a moderate condition, he said.
NZ Transport Agency Waka Kotahi issued road ice warnings for the area, including on SH85 between Alexandra and Omakau, and Kyeburn and Alexandra.
