He was jailed in May 2008 but was freed by the Parole Board in July after they deemed he was no longer considered an "undue risk" to the safety of the community.
A number of release conditions were imposed - one being that Masters was forbidden from associating with gang members unless a specific exemption was made by his probation officer.
He was also banned from entering "any areas where gangs congregate" including "fight clubs and gang pads".
In November the Herald revealed that Masters had been charged with breaching a condition "in that he associated with a known gang member".
Court documents do not state who that gang member was.
Masters pleaded not guilty to the charge.
He was almost killed in April when he was shot in the torso in a daylight attack at a Mt Wellington motorbike shop.
Aukustino Tae - a patched member of the Tribesman gang - has been charged with the attempted murder of Masters.
The pair were friends for many years.
Tae is defending the charge and is expected to appear in the High Court at Auckland next month.
Masters has reportedly refused to speak to police or make any kind of statement about the incident.
