Police have received a number of reports in recent days of counterfeit bank notes being used at retailers around the North Island.
The notes have been $20, $50 and $100 denominations. Typically the offenders have gone into shops and supermarkets, purchased a small item using a large denomination note
and then received legitimate cash as change.
Senior Sergeant Simon King of the Wellington District Command Centre said retailers should be alert to this practice, especially over the busy Easter weekend.
For information to help identify counterfeit notes, people can go to the Reserve Bank of New Zealand website at www.rbnz.govt.nz and look under "notes and coins" where they will find information on how to spot a counterfeit.
Mr King said if retailers were suspicious about cash being used in their shops, they should take the following action.
