Simon Botherway is headed back into the funds management business.
Mr Botherway, who heads the establishment board setting up the Financial Markets Authority, will run ANZ Wealth's Investment Management operation.
The operation has more than $12 billion of funds under management.
ANZ Wealth managing director John Body says Mr Botherway's championing of stronger investor rights and his experience as a regulator will benefit the bank.
Mr Botherway says with the industry's focus on Kiwisaver, the new role extends his experience beyond the boutique funds management sector.
Mr Botherway will start his new role in early May.
He will step down as a director at Fisher and Paykel Appliances at the end of next month, and with the FMA and Securities Commission when the new regulator starts up.
