Wilson is arguing at the High Court in Wellington today to have the 17 strict release conditions relaxed.
Especially in question was the tracking of his movements by satellite.
Wilson's lawyer Andrew McKenzie said Wilson's offending largely took place in his home against women and children.
He would "groom" victims and then abuse their trust rather than abducting children off the street, he said.
Mr McKenzie said the house at Whanganui Prison, if that was where Wilson ended up, was not a place where he could bring potential victims.
"He's accepted those conditions."
Because the release conditions included not having women or children at his home, a lot of the risk against the public had been mitigated.
He said a number of the conditions therefore go too far.
Mr McKenzie questioned the condition of satellite tracking.
"If you've got two minders on either side of you wherever you go, why do you need GPS?"
He said Wilson was better off in jail.
"At least in jail you can talk to other people, walk around and play cards.
"He's effectively under house arrest and that goes too far."
If he breached his conditions, he was liable to be recalled to prison.
Mr McKenzie said there were special conditions that had to apply before GPS monitoring could be imposed, and those conditions did not exist.
"(GPS) is not to look into the future to see what he's up to."
