Macdonald, 32, killed 19 calves by hitting them on the head after a farmer caught him and a young accomplice, Callum Boe, poaching deer in June 2007.
He also burned a 110-year-old whare down and emptied a milk vat on a neighbouring farm causing thousands of dollars of milk to be lost.
The acts were committed against the farmers "for retribution" after Macdonald and Boe were caught poaching Sumbar deer and were trespassed from the farms, between Foxton and Himatangi, in the lower North Island.
The charges were kept from the murder trial jury because the trial judge, Justice Simon France, ruled them inadmissible, partly because they would have been too prejudical.
A spokesman for the judge last night said it was inadvisable for media to publish details.
However, Justice France issued a minute this morning allowing the charges to be reported.
Macdonald was found not guilty of murdering his brother-in-law Scott Guy last month after a month-long trial.
During the trial a four-hour interview Macdonald gave two detectives was played to the court where he confirmed other acts of arson and vandalism - directed at Scott and Kylee Guy - but insisted he was not responsible for the murder.
He told the officers he was "not that extreme" that he would take someone's life. "It looks obvious, these leading up to events, but I'm not that blimmin' psycho."
The judge that sentenced Boe said he "readily admitted" his actions when police investigating the murder of Scott Guy visited him in his new home of Queenstown, in April 2011.
Boe's confessions provided police with the crucial breakthrough they were hoping for and they arrested Macdonald for murder soon after.
They alleged he killed Mr Guy as a rivalry over the family farm - but he has always maintained his innocence.
Court documents viewed by the Herald , show Boe went along with Macdonald, whom he viewed "as a leader" and was under the influence of him.
The crimes took place in August 2007, soon after Macdonald and Boe were caught poaching on Graham Sexton's Foxton farm.
When they were caught by the neighbour, Paul Barber, who phoned police, Macdonald tried to claim he was only "photographing deer". He later aplogised for his actions at a meeting at Mr Sexton's home and he returned a number of stag heads of animals he'd shot on the property.
But seven months after the calves were killed and the milk vat sabotage, he and Boe returned to Mr Sexton's farm and burned the whare down.
It had no electrical connection and was used mainly as a sleep out and by duck shooters and was found smouldering on March 22, 2008.
Macdonald's wife Anna, who is Mr Guy's sister, gave evidence during the trial that her husband's relationship with Boe was an immature one, and she was unaware of what they were doing on their regular night "missions".
During Macdonald's trial his lawyer Greg King -speaking of the acts against the Guys - said his client had admitted some heinous things and would be punished, but that did not mean he was a murderer.
The suppression order was supposed to be lifted when Macdonald appeared in the Palmerston North District Court for a callover on Tuesday, but were continued by the district court judge who declined jurisdiction to sentence Macdonald.
He will now be sentenced by the High Court later this year - a sentencing date will likely be set when he next appears in court on September 14.
