Businesses in the capital have been told to be on high alert for fake money, after someone was caught trying to pay with fraudulent $50 and $100 bank notes.
Wellington Police are making enquiries to establish the source of the counterfeit cash, but businesses are urged to be on the lookout - and report it straight away.
Detective Senior Sergeant Nick Pritchard says as part of the investigation, a person in Lower Hutt who was found in possession of 14 fake $100 notes has been charged.
"It's important for people to understand it is both an offence to make, use or be in possession of counterfeit banknotes," he explained.
"The Reserve Bank of New Zealand has clear guides outlining the security features of New Zealand banknotes and how to spot counterfeit notes.
"Security features are the same on all denominations, and businesses involved in handling money should be aware of security features within New Zealand banknotes."
Det Snr Sgt Pritchard advises businesses who believe they're coming into contact with counterfeit money to refuse it, and immediately report the interaction to police.
If the bank note has already been mistakenly accepted, he says it should be put in an envelope to avoid further handling.
"Anyone with information about the manufacture or distribution of counterfeit banknotes is asked to contact Police on 105," Det Snr Sgt Pritchard said. "Information can also be provided anonymously through Crimestoppers on 0800 555 111."
