"The work has to be cool enough to resonate with taggers and I think the graffiti guys recognise what I'm doing - they recognise the technique and the medium.
"I would definitely like to think I provide a service to the community and the city as an artist, as someone who goes around painting the streets or walls within the community."
Charles Flanagan, Tagbusters team leader, said the Hamilton City Council had an annual budget of $700,000 for graffiti removal, with $15,000 of that committed to "proactive tactics" such as Shirley's art.
He said Shirley's designs had appeared on 23 bus stops, seven toilets and the Melville Park Building and Cobham Drive Bridge over the past two years and the results had been very pleasing.
Mr Flanagan said that although Shirley's art work was far from asilver bullet it seemed to deter taggers.
"Jeremy's murals do seem to be having the desired effect - tagging has reduced at the sites where he's done his murals," he said.
"We have much anecdotal and verbal evidence to support the appreciation of the art, and believe the bus shelter murals have proven to reduce graffiti in those shelters.
"Additionally, it appears to have been a catalyst for other painted public artwork in the city."
