Kiwibank says it won't be stepping in to fill the void left by Westpac's proposed branch closures.
First Union says Westpac is planning to close up to 19 branches across New Zealand many of which are in small towns.
Three towns - Ranfurly and Fairlie in the South Island and Raglan in the North Island would be left with no full-service bank branches if Westpac goes ahead with its plans leaving residents driving up to an hour to get to their nearest branch.
Paul Brock, chief executive of Kiwibank said whilst the bank was always looking at opportunities, it did not see the proposed Westpac departures as a reason to move into those towns.
"I don't see any plans in that space at that the moment."
