The 61-year old Australian native was arrested in his home on July 18 and accused of possessing and consuming alcohol, which would violate the terms of his house arrest. Rudd was sentenced to eight months of home confinement on July 9 after pleading guilty to threatening to kill a former employee and possessing methamphetamine and marijuana.
On Monday, the New Zealand judge allowed the drummer to remain in home confinement while he waits for a November hearing on the possible violation. The judge also ordered that Rudd must undergo regular drug and alcohol tests at the request of police.
If the judge finds Rudd guilty of breaking the terms of his conditions, he could face further punishment, including possible prison time.
The Associated Press reported that when Rudd exited the courthouse on Monday, he told reporters, "The only thing I'm nervous about is I don't, I don't actually don't know what's going on." He also said he would be spending the rest of his time on bail focusing on "self-improvement."

Strange behavior in front of the media has become a regular courthouse feature from Rudd. At one hearing he jumped on the back of one of his security guards and reportedly winked at journalists.
Although Rudd has said that he hopes to return to AC/DC as the drummer after his home confinement, his future with the band remains unclear. Earlier this year, the band announced that they would be launching the "Rock or Bust" North American tour in August, with Chris Slade substituting for Rudd.
Representatives for AC/DC did not immediately respond to PEOPLE's request for comment.
