Power was cut to about 440 homes in Carterton on Thursday, after a power pole was hit by a vehicle overnight on Wednesday.
Contractors replaced the pole along State Highway 2 after it was reported damaged.
A Downer representive said many upset residents had approached them to see what was happening when power was cut just before 1pm on Thursday.
A police media spokesperson said there was no record of a crash being reported overnight.
The Times-Age reported last month that drivers knocked down an average of one power pole every three weeks in Wairarapa.
In the past 24 months, more than 33 power poles have been struck by vehicles in the region.
Powerco owns the power poles that carry network lines in Wairarapa.
Networks operations manager Phil Marsh said overhead power lines were often brought down when vehicles hit power poles, creating a hazard for occupants and the public.
He said network damage from vehicles often caused power cuts to surrounding properties.
