Christchurch residents are being warned of a door-to-door scam that touts mass-produced prints as artworks worth hundreds of dollars.
Police say the scammers are largely foreign backpackers going door to door representing themselves as art students and selling paintings.
The prints are being touted as original works and given price tags of hundreds of dollars.
Acting inspector Glenn Nalder says the paintings are actually mass-produced and can be bought online for a few dollars each.
Police first heard about the scam earlier in the week from a member of the public.
