Retailers are being warned to be on the lookout for counterfeit bank notes after a number of reports of fake cash being used across the North Island.
Notes in $20, $50 and $100 denominations have been used in the scam, police said, in which a small item from a shop or supermarket is paid for in a high denomination note. The offenders then receive change in legitimate bank notes.
"Retailers should be alert to this practice, especially over the busy Easter weekend," Senior Sergeant Simon King of the Wellington District Command Centre said.
If retailers are suspicious about cash being used in their shops, Mr King advised them to take the following action:
• Consider refusing to accept the note.
