Judge Atkins told Marlow that her "performance" yesterday led him to believe sentencing might need to be more restrictive than community work.
Marlow is facing additional charges, including one of obstructing police and one of possessing a pipe to smoke methamphetamine.
One of the co-accused and Marlow's partner, Jordon Hanson, is due to appear for sentencing next week, while Tyson Lewis was sentenced to 175 hours' community work for his part.
Debra Paulson has been charged with receiving the stolen meat but has pleaded not guilty.
She is due to reappear for a case review in November alongside the fourth co-accused, Hamish van der Wiel, who has also pleaded not guilty.
