The Mount Maunganui Post Shop and Kiwibank will close later this month.
The branch will close on July 28 with postal and courier services shifted to the nearby Paper Plus store because Kiwibank had ended its contract. PO Box services and a Kiwibank ATM would remain at the site.
Franchise owner Clint Wishnowski said NZ Post was re-evaluating its sites around the country and had decided it was no longer viable to continue running the Kiwibank there so ended the contract.
The shop had offered four services - Kiwibank, postal services, a bill paying service and post boxes, he said.
Mr Wishnowski said Kiwibank and the bill paying services accounted for two thirds of the business. The loss of that contract meant they had to close because operating just the Post Shop was not viable.
