David McLean has been appointed chief executive of Westpac New Zealand.
He had been acting CEO of the Australasian bank's local arm since August, when his predecessor, Peter Clare, resigned to recuperate from heart surgery.
McLean, a New Zealander, was previously managing director of Westpac Group's New York branch.
His appointment to the top role is a departure from common practice, as Australians have tended to hold the position in the past.
McLean's appointment was announced by Brian Hartzer, who has taken over as chief executive of Westpac Group today, replacing Gail Kelly.
