The charges were not revealed to the murder trial jury, partly because they would have been prejudicial.
Macdonald had already served more than a year in prison while awaiting trial.
He was denied parole last December after the board found it was not satisfied he no longer posed an "undue risk to the safety of the community''.
The parole board confirmed today that his second parole board hearing will be held at Christchurch Men's Prison next Monday morning.
APNZ understands Macdonald will be represented at the hearing by a lawyer. He was not legally represented during his first parole board hearing.
Mr Guy, 31, was shot and killed at the end of the driveway of his Feilding home in the pre-dawn darkness of July 8, 2010.
