BNZ says it is consulting with staff on potential changes to some parts of its business.
“From time to time, we look at how some teams are resourced. Sometimes we recruit and create new roles, other times it may mean some teams get smaller. We are currently consulting on proposed changes in some areas of the business," a BNZ spokeswoman said.
"Because we are in consultation phase, we are not able to share any detail or to speculate on what the proposed changes may be," she added.
The bank has 4,500 permanent full time staff and 760 permanent part time staff.
A spokesman for First Union, the bank workers' union, told interest.co.nz, “We’ve been reassured that our members aren’t affected, but it’s always concerning to learn people could be put out of work.”
First Union represents about a quarter of BNZ's full-time staff.
More broadly, the First Union spokesman said after recent branch closures by ANZ and Westpac, it was "tough watching major banks like ANZ and Westpac, some of the most profitable companies in the country, put people out of work.”
