Power has been restored to 420 homes across Whanganui after repairs were made on Wednesday.
A Powerco representative said a power pole in Gonville, damaged when it was hit by a truck on Tuesday evening, had been replaced.
The crash caused a power outage for 357 Gonville customers, with power restored by 8.20pm on Tuesday.
A field crew returned to the site on Wednesday evening to replace the pole.
Powerco said the repairs were made in the evening to avoid an outage that would have affected Gonville during business hours.
