The Bank of New Zealand looks set for a major shake-up on the back of a departure by one of its top executives.
Shelley Ruha, who has been with the bank for 29 years and is currently the head of its flagship partners division is to leave the bank at the end of February.
There is speculation that the bank will merge its partners or business banking division with its retail division in the wake of her departure.
A BNZ spokesman said it was Ruha's decision to leave and the company had announced her resignation to staff earlier this month.
"Shelley's decision to leave has given the executive a chance to look at the shape of the business."
