Petrol company Z Energy won top honours in the Deloitte Energy Excellence Awards last night.
Roger Sutton, the face of Christchurch lines company Orion after the earthquakes, won the award for outstanding contribution to the sector.
Mercury Energy won retailer of the year.
The judges said Z had a stellar year.
"The company successfully rebranded and localised an otherwise decentralised operation ... returning a healthy earnings lift in the process," they said.
