He is due to be released next week, and a Department of Corrections lawyer, Ian Auld, yesterday asked the Masterton District Court to hear an application for special release conditions to be imposed.
Mr Auld said any conditions relating to Patterson's previous sentence would have been suspended due to the fresh convictions in 2015, and asked if the court could deal with the issue before Patterson's release on Tuesday.
Parole had not had the opportunity to impose special release conditions as Patterson had reoffended while still in jail, Mr Auld said.
Any conditions now would be targeted at his risk of reoffending, he said.
However, Patterson's lawyer, Jock Blathwayt, said the department had had months to raise the issue and it was unfair to rush things now.
"He's served his time and I'm conscious that he gets a fair hearing and it's not simply going to happen at the end of the list today.
"The probation service had months to come up with this and it's an abuse of process to try and fix up something that they say the parole board and the sentencing judge were wrong on."
He also questioned whether the court had jurisdiction to deal with the matter.
Judge Barbara Morris said while it was important that the issue was resolved quickly, a "few days after release isn't the end of the world".
The parameters between the sentencing act and the parole act were a "nightmare", Judge Morris said.
"[This has] a complicated history and potentially a complicated future."
She noted the department had begun the proceedings at the start of July.
"Judge Cameron didn't impose any special release conditions and Section 31 (1) of the Parole Act says that the conditions, if they were in place, would be discharged.
"That's left us in a position where Mr Patterson will be released without any special conditions and parole says there should be some imposed now."
Mr Auld said it was possible the department would seek interim release conditions.
"It's not an ideal situation and one that the department is partly responsible for."
A date has been set for early next week to see when the hearing will go ahead.
