As many as 6000 customers may have been affected when Kiwibank had a problem on Sunday that affected some ATM and EFTPOS transactions.
Communications manager Bruce Thompson says all systems are up and running now but that identifying customers who were affected had been more difficult than first thought.
“Our original intention was to try to remedy it in one fixed run on Monday,” he says. “However, this was difficult and we decided to progressively work through them.”
He says about 6000 customers may have been affected but the number may also have been much smaller because some had tried several times to access funds, being debited each time without getting the money.
“There may be some tidying up to do in relation to some fees,” he says. That may also affect end-of-month back fees, which will be charged but then reversed.
The bank had given emergency overdrafts to some customers in need.
“We were swamped with calls on Sunday,” Thompson says. “We had taken down parts of the system at 2am for scheduled maintenance but when we brought them back up some parts were not functioning correctly.”
