ANZ says it’s reviewing the manual process which caused it to take 24 hours longer than the country’s other trading banks to recover from a computer problem on Wednesday night.
Whereas other banks had caught up with a backlog of payments resulting from the computer glitch by midday yesterday, ANZ only did so today.
“We’re trying to ascertain what the processing problem was,” says ANZ marketing head Mark Thomas.
Thomas says the bank thought it would take until midday yesterday to complete manual checking of payment data but the process ended up taking longer "perhaps because we have more customers".
The bank says it will waive fees and interest charges incurred by thousands of customers affected by the problem.
The disruption began with a power failure at the Mt Wellington data centre of computer services company EDS, which handles interbank transaction processing. The 30-minute outage affected payments for customers of all the trading banks.
EDS was unable to explain what caused the problem.
Thomas says a “standard operating process review” takes place after such occurrences.
“No one is terribly happy about it but it was a situation out of our control.”
