ANZ announced that its chief risk officer will retire at the end of March 2018.

Nigel Williams joined ANZ following the 2004 acquisition of The National Bank of New Zealand. At ANZ he has held a number of leadership roles including managing director Institutional, Corporate and Commercial Banking in New Zealand, and Managing Director, Institutional Australia.

Since 2011 Williams has been ANZ’s chief risk officer and a member of the Group Executive Committee. He has also been a director of ANZ Bank New Zealand and Shanghai Rural Commercial Bank, the Melbourne based bank said in a press release.

Williams' intention is to now pursue a career as a non-executive director, meanwhile ANZ expects to announce a successor in early in 2018.

ANZ along with Australia's so called other big four banks are about to face what could be a year long royal commission into misconduct into the country's banking and financial services sector.

The enquiry comes following a series of high profile misdemeanours. ANZ, Commonwealth Bank of Australia (CBA), National Australia Bank (NAB), and Westpac have been under growing political pressure.
