We’re making some changes to our branches

With more and more New Zealanders doing their banking online, we need to make some changes to our banking services. From December 2020, we’ll be closing a number of our branches. We’ve been in touch with customers who use these branches regularly, and we’re committed to providing them with accessible ways to do their banking.

Branches open during COVID-19

All of our branches are open, with a range of additional measures in place to help keep you and our people safe. Open branches and operating hours may change, so check our branch and ATM finder before visiting a branch.

All Partners Centres are open for customers.
