ASB chief executive Charles Pink has resigned for personal reasons, and will be leaving the bank following a scheduled board meeting on Tuesday.
Chief executive retail banking Ian Park would take up the role of acting CEO until a permanent replacement was announced, ASB said today.
"The board of ASB is sad to be losing a chief executive of the calibre of Charles," chairman Gary Judd QC said.
"Charles has provided the bank with outstanding leadership over the past two years, and his legacy is a clear strategic direction, a strong leadership team and soundly performing bank."
Mr Pink had advised the board of his decision to resign in early September, and had agreed to delay an announcement while the board considered the steps it wished to take to appoint a replacement, Mr Judd said.
Mr Pink joined ASB as chief executive in January 2009. The former chief executive of Barbados-based FirstCaribbean International Bank had had an 18-year career in personal and commercial banking with Barclays.
Mr Park has been an ASB executive for 23 years.
