"Our customers are always asking us for faster, easier ways to do their banking," he said. "What we see through this [app] is we can bring to life everyday banking in a very easy to use and visual way and that really is going to take everyday banking to the next level."
Pomeroy said that not long ago augmented reality was considered a "futuristic prop" in the movies but a growing number of people believed it had the potential to change our lives as much as the internet and mobile phone.
"From the moment we saw the concept for this app in our crowdsourcing competition in the United Kingdom and started to develop it the impact augmented reality can have in adding a new dimension to mobile banking became apparent," he said.
"This is the first time it has been used for account management in banking and we see a number of possibilities for it in the future."
Pomeroy said Westpac was pushing to become "the number one digital bank in New Zealand if not the world".
"For us this is all about driving customer experience and customer engagement," he said.
Last month Westpac announced it was trialling a new digital payment system, which would allow customers to use their smartphones to make payments at electronic terminals.
