"It's fine - we always do lots of succession planning," he said. "[Victoria's] a very exciting and different candidate for Auckland."
Crone was elected to the board of Contact Energy last week, and will earn standard fees of $126,500 for that role, plus additional fees for committee services.
At the company's annual meeting last week Crone told shareholders that she would be making a decision on the mayoralty bid this week and that she had told Contact's board that "if something were to happen" the firm would remain her "top priority".
Meanwhile, Auckland Chamber of Commerce chief executive Michael Barnett, previously thought to be another centre-right contender for the mayoralty, said he would not be standing.
"With a clotted market I think there's going to be a bit of dilution of the vote occurring," Barnett said.
"It's not an attractive environment to be putting up your hand, frankly."
He said he wished Crone luck in her bid.
Other contenders include Orakei local board member Mark Thomas, right-winger Stephen Berry and activist Penny Bright.
