ANZ is on the hunt for a new chief information officer following the sudden departure of Anne Weatherston.
Weatherston will leave the bank next week, with chief operating officer Alistair Currie taking on her responsibilities while a global search for a permanent replacement is carried out.
Weatherston joined ANZ in 2010 from Bank of Ireland, where she spent four years as Group CIO. Previously she was information technology director at Abbey/Santander and has also worked for RBS and NAB.
The bank gave no reason for her surprise departure.
Says Currie: "We have made very significant progress under Anne's leadership by establishing a transformation roadmap for ANZ technology aligned to ANZ's super regional strategy.
"This has seen ANZ strengthen technology infrastructure, introduce new customer channels including mobile goMoney and ANZ Transactive, deliver new global processing systems in payments, loans and markets, move to a single core banking platform in New Zealand and develop a first class technology organisation to support our business."
