Air New Zealand is again under fire from a consumer watchdog that claims the airline's reluctance to issue refunds means it has locked away millions of dollars.
Consumer NZ says customers are being "short-changed" by the national carrier's preference to provide credits rather than to return money.
A survey by the watchdog found 80 per cent of passengers on cancelled Air NZ flights have been left stuck with credits - allowing the airline to sit on "millions of dollars of customers' money".
"The majority of customers have only been given credits and many didn't know if or when they'd be able to use them," chief executive Jon Duffy said.
Consumer NZ surveyed more than 2000 Air NZ customers and found that only six per cent had been given refunds after flights were cancelled due to Covid-19 lockdown.
