Outgoing Commerce Minister Simon Power has been named as the new head of Westpac Private Bank.
Power, 41, is joining the bank in January next year after being an MP for the past 12 years and a Cabinet minister for the last three.
Westpac chief executive George Frazis said Power brought "a range of skills and experience to the position that fitted well with the purpose and focus of Private Bank."
Westpac Private Bank is described as the part of the company that "delivers a relationship banking service to our premium personal customers."
"We are enormously excited to be joined by someone with such an outstanding record of leadership and achievement at the highest level" said Frazis .
