Mercury’s chief executive Vince Hawksworth is to retire, effective from August 31.
He will be replaced by Stew Hamilton, the energy company’s current executive general manager generation, the company said.
Hawksworth has served as CEO since March 2020.
The company said Hawksworth had overseen a period of significant growth at Mercury, leading the company through the construction of the Turitea Wind Farm and two major acquisitions, adding the New Zealand assets of Tilt Renewables and the Trustpower retail business to Mercury’s portfolio.
