"It's easier to get in trouble, it's harder to get out."
Truscott was kept under intense supervision for 10 years until 2009 in various Government-funded locations, including in Merivale and Selwyn, at a cost of up to $300,000 a year.
He escaped multiple times, often going back to Hagley Park where one of his sexual liaisons occurred.
Canterbury Medical Officer of Health Cheryl Brunton said Truscott's supervision ended some years ago and he was now a "private citizen."
Dr Brunton said the Canterbury District Health Board was not aware of Truscott's busking, as it posed no threat to public health.
"HIV cannot be passed on by casual contact or being in the same geographical area as (an) infected person with HIV. Transmission of HIV requires close contact with blood or bodily fluids."
Truscott said he had been busking every day around central city tourist spots and Cathedral Square's Friday Street Food Market for about six weeks because it was a good money earner.
"I've got my freedom back and I'm keeping it," he said.
"I don't do those things anymore."
