Some of the branched are closing but they still have the largest branch network in NZ and sometimes branched reopen and get moved because of customer demand. It is not a good ides to have a branch open with 5-10 staff to service 50 people when there is another branch 10 min drive down the road. By memory there are about 23 branched in CHC
I personally have not been in to a branch other that to set up my account with NBNZ or Kiwi. I get my pay put in electronically, have an EFTpos cards, Visa debit card, Visa (credit) card and internet banking so have no need for a branch.
Note: everything I say here is my opinion and not that of my employer
