Police in Northland are warning of a sophisticated Eftpos card-skimming fraud which may have been used elsewhere in New Zealand.
The scam involves an individual posing as a courier driver who delivers a package but demands a small payment for delivery.
A shop owner in Kerikeri was targetted on Christmas Eve and several thousand dollars have since been withdrawn using a duplicate copy of the card.
The offender was wearing a green shirt with the company logo NZ Transport Ltd.
Three similar incidents were reported in Whangarei on Wednesday in what police say appears to be a carefully planned scam.
