The paintings in Moray Pl - a moa by UK artist Phlegm and lace by Polish artist NeSpoon - were added to Dunedin's growing collection on February 29 and March 3 respectively.
Mr Muir said a network of overseas artists was now talking about Dunedin as an art destination.
‘‘We've now developed a reputation about this [movement] and they want to come to Dunedin.''
Phlegm and NeSpoon knew each other, but did not know they would be in Dunedin at the same time, Mr Muir said.
Dunedin's growing street art collection was becoming a drawcard for tourists, he said.
‘‘There's a lot more foot traffic in the city because of it.''
