David McLean, who has been acting in the role since August 2014, will continue as chief executive following the resignation of Peter Clarke last year.
Mr McLean’s appointment is the first official decision by Mr Hartzer, who officially took over the reins from Gail Kelly today.
“I am pleased we are able to appoint someone that I know is already deeply respected and known in the New Zealand business community,” said Mr Hartzer.
“We continue to see potential to grow and support our New Zealand customers and I’m pleased that an executive of David’s calibre will be leading the New Zealand operation,” said Mr Hartzer.
“David is one of New Zealand’s most experienced bankers with extensive knowledge of Westpac’s operations, having been with the group for 16 years in a number of senior positions across both retail and institutional banking,” he said.
Westpac New Zealand chairman Peter Wilson said that the company will benefit from Mr McLean’s “strong leadership skills and local knowledge”.
“His in-depth knowledge of all facets of the local organisation will deliver positive outcomes for New Zealand customers and employees,” said Mr Wilson.
Mr McLean said the appointment was an honour.
“I look forward to continuing to support our customers, our communities and to take a role in supporting this country to grow,” said Mr McLean.
