Barbara Chapman has only been chief executive of the ASB Bank since April last year but already she had stamped her mark on the company.
The bank reported a record profit of $685 million for the year to June 30 - up 21 per cent on the prior year.
Figures supplied by the Bankers Association show that ASB had the highest average return on equity for the last five years compared to its competitors, at more than 15 per cent per annum.
ASB's return on ordinary shareholder equity was 19 per cent for its 2012 financial year, up from 17.2 per cent in 2011.
