Former Prime Minister Jenny Shipley will step down as Genesis Energy chair after this year's annual meeting in October, and be succeeded by ex-ASB Bank chief executive Barbara Chapman.
Shipley, who is among former Mainzeal directors facing a civil suit from unpaid creditors of the failed construction firm, will end a nine-year spell as chair of the electricity generator-retailer.
During that time, she ushered it from a pure State-owned enterprise to one of three partially privatised and listed companies under the mixed ownership model of the previous administration.
Chapman joined the board earlier this year as she transitions into a new career as a professional director, having led ASB for six years.
Her appointment to the Genesis board name-checked her skills in disruptive innovation, marketing, digital transformation, consumer technologies and driving leading brands.
