Police have issued a public warning about the spread of fake cash after arresting a Henderson man on currency and counterfeit offences.
Police say counterfeit $100 notes were being used mainly in the west Auckland area, however, it is believed the offending may be wider spread.
Waitemata police Constable Rebecca Brown said police would like to hear from retailers who may have had customers pay for goods with counterfeit money.
This follows the arrest of a 26-year-old man.
The fake cash, which consists mainly of $100 denominations, had been used to buy petrol, food, and cigarettes from retailers across Auckland, she said.
