There are five new cases of COVID-19 in New Zealand, including one community case and four people in managed isolation.
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 acrossthe 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.

He said that the age of most of the visitors means that use of the app would be high.
"The majority of the people at Mardi Gras will be young, tech savvy, digital natives who would have no problem in downloading and using the Covid Tracer app.
"While I expect most people will be doing the right thing and using the contact tracing app or another method that works for them, for those that aren't or are forgetful there is no problem in calling on them to do so."
He also called on revellers to practice good hygiene and consider wearing a face covering.
