The new hubs will have a Smart ATM and full cash change services, a full-time dedicated concierge, an employee from each bank available on site for a few hours on separate weekdays, a private meeting room, and private areas for phone and internet banking.
Roger Beaumont, chief executive of the New Zealand Bankers' Association, said the trial and associated research had provided extremely useful insights into regional banking, despite significant changes in customer banking behaviour and Covid-19 alert level interruptions.
"The past 12 months have been a difficult time to run a trial, with major changes in customer behaviour accelerated by the Covid-19 pandemic and regular changes in alert levels. We intend to run the next phase until the end of 2023, to give these dynamic changes time to pan out."
Participating banks are ANZ, ASB, BNZ, Kiwibank, TSB and Westpac.
The banks have also renewed a promise not to close any more regional branches until the end of 2023.
This excludes branches in the main centres of Auckland, Tauranga, Hamilton, Wellington, Christchurch and Dunedin. It also does not cover TSB's network in Taranaki.
