The Commonwealth Bank's chief information officer will leave the bank in a restructure initiated by CBA's incoming chief executive officer.
Matt Comyn was appointed CBA's new chief in late January, and will start in the position on April 9.
Ahead of his commencement the bank today announced a restructure of its senior management team that will see three executives including its CIO depart.
David Whiteing was appointed CBA's CIO and head of enterprise services in June 2014 following the departure of former high-profile IT chief Michael Harte.
He had joined the bank less than a year prior as its executive general manager of architecture and planning following a short stint at McKinsey, and longer terms at the IT operations of BP and Accenture in the UK.
Today outgoing CBA CEO Ian Narev thanked Whiteing - and his two departing colleagues, head of institutional banking and markets Kelly Bayer Rosmarin and HR chief Melanie Lang - for their service.
"Leadership transitions are inevitably a time of change in senior teams, as executives reassess their own plans and the bank prepares for its future," Narev said in a statement.
"We thank them for their leadership and wish them all the very best for the future."
Comyn said he had started the recruitment process for the three vacant positions.
He said he was "focused on building a leadership team that will work to exceed the expectations of our customers, the community and regulators" as well as rebuild trust in the bank following a money laundering scandal.
Whiteing's tenure was largely focused on ensuring CBA's IT team was equipped with the skills the bank would need for the future.
Paul Newham, CBA's head of group operations, will act as head of the enterprise services division while recruitment is underway for Whiteing's replacement.
