Eateries can ultimately charge what they like for a product or service but to add a surcharge legally they need to let you know before you agree to eat there. That’s so you have the opportunity to decide if you are willing to pay the extra cost.

Commerce Commissioner Anna Rawlings said it was routine for businesses to use surcharges to offset the cost of having staff working on a public holiday.

“However, if a surcharge is applied, it must be clearly disclosed and the reasons for the surcharge must not mislead customers,” she said.

If you feel like you’ve been misled about a surcharge over the long weekend, you can contact the Commerce Commission on 0800 943 600. Consumer NZ members are also welcome to contact our advisory service with inquiries.
