Westpac said moving the roles to Auckland would unify its technology, product and marketing hub in one location, a decision arisen out of a new opportunity to acquire more floor space at the bank's headquarters in the Britomart precinct.
Karen Silk, Westpac NZ Experience Hub general manager, said the current arrangement had worked well, but the chance to centralise teams in Auckland offered a fresh opportunity.
"Our team based in Wellington has produced some exceptional results with their colleagues in Auckland. However, we think collaboration and teamwork can be taken to the next level if we take the opportunity to bring all of our people under one roof.
"This will benefit our customers through the faster and more efficient delivery of new products and services."
Westpac said the changes do not affect any bank branches or branch employees.
Tali Williams, FIRST Union secretary for retail, finance and commerce, said no FIRST members were affected by the restructure.
