Fake notes used in shops
Retailer are being warned to keep a look out for counterfeit cash.
Police say the $100 and $50 notes have been used on three separate occasions since October.
They want to identify a man who used a fake $100 note to pay for a coffee at a Pak 'n Save supermarket in Glenfield on January 14.
Just before Christmas a fake $50 note was also used at a North Shore butcher shop and in late October another fake $50 note was used at a Glenfield clothing store.
A 21-year-old woman was charged with misuse of a document in relation to the Glenfield incident last year.
Police now wish to identify the man believed to be responsible for using the false currency at Pak 'n Save.
He is described as a European man with ginger hair, wearing a red back pack and riding a mountain bike.
Police say inquiries are under way to establish whether the three cases are related.
"If you're receiving a large denomination of money, take a look closely at the notes. If the paper feels odd or it just doesn't look right, contact the police," Constable Simon Hooker says.
Anyone with information on the identity of the man at Pak 'n Save is asked email email@example.com with details.
Information can also be given anonymously to Crimestoppers on 0800 555 111.
