This seemed to only affect a specific customer and not any Viaduct customers but he eftpos outage at supermarkets around Wellington this morning were caused because systems were unable to cope with today's leap day date.
The outage, which has now been resolved, affected many New World, Pak n' Save and Four Square stores across the lower North Island from early this morning.
Eftpos machines in the stores were down when shops opened and were restored about midday.
George Sutherland, brand general manager at Foodstuffs Wellington, said customers were still able to shop using cash and credit cards.
"It is our understanding that the fault created in our point of sale systems stemmed from an error relating to today's date, February 29. Our sister companies in the upper North Island and South Island were unaffected as they have different point of sale systems."
Richard Taggart, owner of New World Metro supermarket on Willis St in central Wellington, said its eftpos was down when it opened the store at 7am.
There was a staff member at the door telling customers they would need to pay with cash.
Pak n' Save Kilbirnie and Petone, Pak n' Save Hastings and New World in central New Plymouth, were also affected by the outage. It has all been resolved now. Roll on March.
