Spammers are using Auckland's new AT HOP passenger transport cards to rip off people.
Auckland Transport says passengers are being approached on trains by two people offering to sell AT HOP Cards for $20 cash.
They are told the cards have $50 loaded onto them.
However, the cards being offered are ones that have been cancelled, as they have been reported lost.
And a couple in Papatoetoe who were approached by a group of three people going door to door offering to sell AT HOP cards.
They filled in a fake form and were told the cards would be posted to them.
They paid up - but have heard no more.
