The Mayor of Ruapehu District has called on all businesses in Ohakune to enforce a "No Scan - No Service" policy ahead of the ski town's annual Mardi Gras weekend.
Mayor Don Cameron made the request ahead of the popular festival, which is predicted to see 7000 people from across the country head to the small town.
In a statement, Cameron said it was "critical that everyone follows best practice for keeping our community safe".
"In the event of a community outbreak the ability to contact trace is critical to enabling health authorities to quickly get on top of the situation," Cameron said.
