Powerco's long standing chief financial officer Elanga Ekanayake is retiring and Dennis Martin has been appointed to take his place.
Martin comes to Powerco from the New Zealand Refining Company where he held the role of chief financial officer since 2001 and more recently strategy and planning manager.
Ekanayake will be leaving Powerco at the end of May 2010, following a handover of responsibilities to Martin.
Powerco chief executive Richard Krogh says Ekanayake made a major contribution to Powerco's consistently strong financial performance and stable credit profile during more than two decades of significant change in the electricity industry.
"During his time with Powerco, Elanga has seen the Company grow from a division of the New Plymouth District Council to the second largest electricity and gas distribution utility company in New Zealand."
