A fraudster is wanted by police, who say he has scammed $30,000 from Trade Me users by texting them and offering them iPhones.
Police say Joshua Colin Calthorpe, 32, does not have his own account on the auction site, but trawls through other users' listings to find victims.
He targets people who have left their contact details in the question and answer section of an auction - usually for iPhones.
"He views the auction listings and records the contact details of the interested buyers. He will then text or email them posing to be the seller from the auction they expressed interest in," said Counties Manukau police spokeswoman Ana-Mari Gates-Bowey.
