Nigel Williams will step down from the role at the end of March 2018, having started in the position in 2011 after joining the major bank in 2004, according to a statement.
Prior to his role as chief risk officer, Mr Williams held positions such as managing director, institutional, corporate and commercial banking in New Zealand as well as managing director, institutional in Australia.
He also previously held director roles for ANZ Bank New Zealand and Shanghai Rural Commercial Bank.
Commenting on his departure, ANZ chief executive Shayne Elliott said Mr Williams had “led the transformation” of risk with a focus on data analytics, automation and cyber security.
“He has also played a leading role in the resolution of a number of business and regulatory issues, and in significantly improving ANZ’s risk profile,” Mr Elliott said.
He added that Mr Williams’ intention was to pursue a career as a non-executive director after 33 years in banking.
“This is a natural next step given his banking and data experience, and background on a number of boards at ANZ and externally including NZX Limited and the New Zealand government’s taskforce on capital markets development,” Mr Elliott said.
“He can be proud of many achievements in his time at ANZ and we wish him every success with his future career.”
Mr Williams’ successor will be announced “early in 2018”, according to the statement.
