Ewen Macdonald has been denied parole at his third Parole Board hearing, more than three years into a five year jail sentence.
Macdonald was found not guilty of the 2010 murder of his brother-in-law, Scott Guy, but was later jailed for five years for arson, vandalism and killing livestock. He has been in custody since April 2011.
In today's decision, the Parole Board said he still posed an undue risk to the safety of the community.
The ruling is the third Macdonald has had his application for parole turned down.
He was denied parole last November when the Parole Board said he posed a clinically significant risk of reoffending.
A forensic psychiatric assessment of Macdonald found he suffered from a significant personality disturbance and had failed to address behavioural issues relating to revenge and envy.
Scott Guy's father, Bryan Guy, said the right decision had been made.
"We're pleased that he is going to spend a bit more time serving his sentence, and there's consequences when you do crimes like he's admitted to," he said.
"So we're pleased that he's going to be there for a bit longer yet."
Mr Guy said his family was firmly focused on looking after each other, including Macdonald's four children, and was not spending too much time worrying about parole board hearings.
Commenting on reports Macdonald had been doing work in the community, he said it was important the prison system did not take it too easy on him.
Scott Guy's wife, Kylee, travelled to Christchurch for today's hearing.
