David Bain will soon discover whether he will get a multimillion-dollar payout for being wrongfully imprisoned for 13 years.
Justice Minister Judith Collins said she had received a report from retired Canadian judge Ian Binnie, who had to decide whether Mr Bain was innocent "on the balance of probabilities".
The minister said she would be meeting Justice Binnie over the next two weeks, and was expected to make a final decision before the end of the year.
Mr Bain was convicted in 1995 of murdering his family and spent 13 years in jail before being found not guilty in a 2009 retrial.
He had been sentenced to 16 years in prison for killing his parents, Margaret, 50, and Robin, 58, and three siblings, Arawa, 19, Laniet, 18, and Stephen, 14, by shooting them with a .22 rifle in June 1994 in Dunedin.
