People travelling on Northland's public bus service can go into the draw to win grocery vouchers for wearing face masks when aboard.
The 'Mask up Northland' campaign, running until December 14, aims to reward continued mask use among bus passengers and encourage further use among those who reluctantly wear them.
Northland Regional Councillor Rick Stolwerk, who chairs Northland's Regional Transport Committee, said wearing a face covering isn't always the most comfortable thing, but it does make a difference to passenger safety.
"With the large variety of mask and face coverings we thought it would be great to see the different coverings passengers are wearing to protect each other on the bus," Stolwerk said.
"To help encourage people to get involved we are giving away 50 x $30 grocery vouchers randomly to those that have entered the draw."
