A burst of fake money being presented to pubs, supermarkets and service stations in Palmerston North has police urging people to be aware.
In the past five days, police have been made aware of at least eight fake $50 notes being circulated in the area.
"We are asking the community to ensure they pay extra attention to any larger denomination notes they come into contact with," Constable Mark Reid said.
"People who work in jobs where they handle cash are also asked to take extra care. Anyone with information should contact local Police or anonymously call Crimestoppers on 0800 555 111."
