Residents at Queenstown's Lake Hayes Estate are frustrated at frequent power cuts.
Delta Utilities confirmed 1100 properties lost power in Lake Hayes Estate, Lower Shotover and Frankton's Glenda Dr on Sunday night after high-voltage overhead lines were downed on Jims Way, Lower Shotover.
Comments on social media talked of a ''big explosion'' and wires arcing.
Power was restored to all properties shortly after 3am yesterday.
Lake Hayes Estate residents also had power cuts on June 4 and May 26.
Delta's communications manager, Gary Johnson, said crews worked through Sunday night to restore power.
''We will be carrying out permanent repair on that section of overhead line on Tuesday morning that may require a short duration outage to enable further investigation and repair work to be carried out safely.''
Jim Robinson, who has lived in Lake Hayes Estate for seven years, said the power supply was substandard and he was considering buying a $4000 generator as a backup.
Houses in Lake Hayes Estate are not allowed woodburners and rely mainly on electrical heating. Mr Johnson blamed the June 4 cut on ''connector'' failure and said Aurora Energy would replace them in coming months.
