Shoppers were left queuing at money machines to pay for goods after the Eftpos system crashed across parts of the North Island at lunchtime today.
Electronic transaction company Paymark reported a 10-minute outage that left electronic machines unable to process payments at checkouts.
Company spokesman Paul Brislen said while he was still finding out details of the fault, the widespread outage had been resolved.
However, social media is filled with reports of shoppers queuing at ATM machines outside Pak'nSave stores in both Kaitaia and Palmerston North after checkouts stopped working.
Shoppers caught out by the unexpected breakdown warned others to take cash if they wanted to buy anything.
