At the time, Pearson was on bail on a charge of burglary.
Judge Phillip Cooper said Pearson had broken into a Four Square last August by climbing up a wall of the building and removing some glass panels but left when the alarm was activated.
Pearson's lawyer, Nicky Scott, said Pearson progressed well if he had someone to confide in and sought psychological counselling for him when he was released.
She said when Pearson rode the motorcycle, which was not stolen by him, he was unable to stop and ended up going out on to the road.
Judge Cooper said Pearson had two previous convictions for drink driving and said the starting point was eight months' jail, but reduced the sentence to six months for the guilty plea.
Pearson had already served the sentence while remanded in custody.
He was banned from driving for a year and ordered to pay reparation of $21. Pearson was also ordered to undergo psychiatric and psychological assessments and receive any treatment or counselling which resulted.
In 2008, Pearson was sentenced to three years' jail for ill-treating and assaulting 3-year-old Nia Glassie, who died after months of abuse by a number of people. He was released in 2010 and his parole conditions ended in January last year.
