New Westpac boss Brian Hartzer has stamped his authority in his first day as chief executive of the Australian banking group, in a shake-up that puts the potential achilles heel of technology front and centre.
However no significant changes were announced from predecessor Gail Kelly's strategy that delivered six years of strong shareholder returns.
Hartzer, aged 47, increased the number of people that report directly to him.
The head of technology, chief information officer Peter Curran, will now report to Hartzer after previously answering to chief operating officer John Arthur.
Hartzer made his own previous job redundant, abolishing the Australian Financial Services division created by Kelly for him to run, with a near Australian record sign-on bonus of more than A$7 million ($7.5 million) in shares.
