NAB has tasked former NSW Premier Mike Baird with leading its retail unit as consumer boss Andrew Hagger departs following his mauling at the financial services royal commission.
Mr Baird, who surprisingly quit as NSW Premier in January 2017 and has led NAB's institutional bank since April the same year, will become chief customer officer for consumer banking.
He will replace Mr Hagger, who last month was criticised by counsel assisting the royal commission for showing "a disrespect for the role of the regulator and a disregard for the gravity of the events in question" over his response to the fees-for-no-service scandal.
Mr Hagger, who has been with NAB for 10 years and part of the lender's executive team for eight, will leave the bank.

NAB chief executive Andrew Thorburn said the separation of the bank's wealth business from consumer operations to prepare for a demerger and IPO was a factor in Mr Hagger's decision to leave.
"With the recent bringing together of the wealth businesses ... to prepare for separation from NAB, Andrew Hagger believes now is the right time to leave," Mr Thorburn said.
NAB shares were flat in early trade on Monday, making them the best performing among the big four banks.
