Air New Zealand's reputation has nosedived over the way it has handled refunds to customers, according to a new survey.
Consumer research company Opinion Compare asked 478 people at the start of the month on how their opinions of major companies had changed.
Air New Zealand's reputation suffered the worst, while that of supermarkets surged.
Opinion Compare founder and chief executive Gavin Male said the airline's decision not to refund customers whose flights had been cancelled because of Covid-19 had "tarnished" its reputation.
"In a time where lots of people are sort of skimping a bit of money, everyone could do with the cashflow."
