Some restaurants have introduced pre-pay systems as a result of an increase in dine and dash incidents.
Results from a Restaurant Association New Zealand survey showed many restaurants had experienced "walk outs" this year.
After inquiries from the Herald on Sunday, the association's chief executive Marisa Bidois surveyed its members. Of the 180 who responded, 18.9 per cent had noticed an increase in people not paying.
"The majority of those said it happened 1 to 5 times a month. We had the odd one who said it happened up to 10 times a month," said Bidois.
She said some restaurant owners now asked customers to hand over credit cards before dining. "It's a security reason. Restaurateurs need to look after their business and to make sure they are getting paid for what is going out.
