An Auckland man sent to prison twice over the same attempted murder is set to be released on parole for a second time.
Martin Lyttelton, 57, in 2008 pleaded guilty to the attempted murder of former business partner Richard Ord, along with shooting Ord's partner, Colleen Fenton, at their North Shore home.
But after serving his sentence of five years and 11 months - half on parole - Lyttelton won a bid to have his guilty plea thrown out in an attempt to clear his name - only to be convicted by a jury and given a longer jail term in May this year.
That meant Lyttelton had to return to prison while the Parole Board figured out how much extra time he would have to serve.
The board has now announced he will be granted parole on Tuesday, meaning he spent two extra months in jail.
"We are unanimous that Mr Lyttelton does not presently constitute an undue risk of reoffending," the board said in its decision release on Monday.
"He spent a considerable amount of time in the community while on parole for the previous sentence and did not reoffend."
Lyttelton's second sentence and his first differed because the original included a discount for a guilty plea.
The board acknowledged it was an "unusual set of circumstances".
The conditions of his release include attending psychiatric assessments and counselling, a ban on owning a gun and not contacting his victims among standard restrictions.
Lyttelton's full sentence was due to run until March 2019.
During the trial, the prosecution said Lyttelton broke into Mr Ord's North Shore house, shooting Ms Fenton in the thigh with a shotgun and trying to stab Ord with a skinning knife.
But representing himself, Lyttelton argued he had no plan to kill Mr Ord, but wanted to commit suicide in front of him.
