Mount Maunganui concert goers will be offered refunds or a rescheduled concert after a power cut left them in the dark on Saturday night.
Promoter Paul Farnan of Pitch Perfect Promotions said about 350 people - many dressed up in full 80s fashion - were seated at Totara St ready for the Automatic 80s Live show to begin when the lights went out.
"They were looking at a black stage."
About 3700 properties in Mount Maunganui were affected by the unplanned outage, Powerco reported.
