Some were helicoptered into Pukehuia, near Dargaville, where damaged to two poles was detected following an aerial survey.
The faults were fixed following an aerial survey the chopper then touching down at each pole while a three-man lines crew completed repairs.
The area was inaccessible by road due to flooding one local farmer described as the worst in over 50 years.
