In December 2015, Parsons strayed from his approved route to work and approached a 15-year-old girl wearing a school uniform. He did it again in May last year, giving her a note with his mobile number and asking her to buy underwear and other female items. As a result, he was sent back to jail.
Parsons has voluntarily engaged in intensive treatment programmes for sexual offending and individual treatment for several years.
However, Justice Nation said Parsons' actions have reduced earlier hopes that he would be able to control his sexual behaviour in an independent living situation.
"I am satisfied Mr Parsons has demonstrated an intense drive, desire or urge to commit 'relevant sexual offences', namely sexual offences against a child or young person. There is also evidence that Mr Parsons has an ongoing predilection or proclivity for behaviour which could result in serious sexual offending."
Parsons highlighted to the court his desire to start transitioning to transgender and his strong wish to be supported in that process.
Justice Nation found these desires also put him at high risk of reoffending if he perceives his sexual and cross-dressing wishes are being thwarted, he experiences stress or has access to potential victims.
Parsons partly blamed the Christchurch Residential Care and Probation for his breaches, as he believed they failed to meet his needs.
But Justice Nation said this showed a lack of acceptance of responsibility or remorse for his past offending and a lack of understanding about the effects of his offending on victims or potential victims.
Other conditions of Parsons' monitoring include not being allowed to own a phone that has access to the internet. He forbidden to have a camera and cannot enter any schools or public places where children under 16 are likely to be.
