Mackle and others appeared to be intoxicated and fights broke out.
Justice Graham Lang said it was unclear whether all the drunken prisoners had accessed Mackle's supply and therefore could not pin the blame on him for fuelling the violence.
Over the following hours furniture was smashed to pieces and fashioned into weapons to cause further damage.
Justice Lang said Mackle broke windows, doors, toasters and sandwich presses but he was not one of the group who broke into the guard room and attacked an officer with a volleyball pole.
He was originally charged with arson after he was seen adding broken items to a huge fire in the middle of the compound.
But the Crown withdrew the charge because he did not start the blaze.
Mackle pleaded guilty to riotously destroying property, which carries a maximum penalty of seven years imprisonment.
The judge highlighted the offender's previous convictions which included aggravated robbery and wilful damage but gave him credit for attending sessions with a prison psychologist.
Mackle was jailed for two years two months, which sees his end sentence pushed back to mid-2019.
A ministerial enquiry into the riot - considered the worst in 15 years - led to a dozen recommendations including reducing prisoners' access to fruit and using alcohol-free cleaning products.
As a result of the large-scale violence 23 inmates were charged with more than 40 offences.
It is understood more than than half of those charged have already been dealt with by the court.
