Power was restored to hundreds of Whanganui properties on Wednesday afternoon after being out since about 5am.
Power was cut to about 200 Aramoho properties after a car crashed into a power pole on Brunswick Rd early on Wednesday morning.
A police spokesperson said the power pole was still standing but was on a slant and the driver of the vehicle had not been located.
Contractors worked throughout the day to get the power back on. A Powerco spokeswoman said power was restored at 4pm on Wednesday.
Stacey Williams, of Staceys Cakes, posted on Facebook that she was baking when the power went out and she had wasted ingredients in a cake she was making for a client.
