Police have released an image of a man spotted near ATM machines targeted in a skimming scam which has netted $1 million from unsuspecting bank customers.
Bank internal investigators and police have struggled to track the scam, the biggest in New Zealand.
Up to 500 cardholders are believed to have used affected ANZ and National Bank machines in Auckland suburbs including Parnell, Ponsonby, Takapuna and Howick.
One man last used his card in Northcote, on the North Shore, and lost $1300, which was withdrawn in Bangkok - a city he has never visited.
Another victim's money was stolen in several $500 withdrawals in South Africa.
