Ewen Macdonald has remarried in a small private ceremony.
The man acquitted of murdering Feilding farmer and his own former best man Scott Guy married Joyce Braas in Dunedin on October 12.
Macdonald's ex-wife, Anna Guy, did not attend the wedding, but told NZME it was a small ceremony, attended by Macdonald and Braas' seven children.
Guy divorced Macdonald, while he was in prison for charges unrelated to her brother's murder.
She said she had met Braas once, "for about five minutes".
Braas' mother, Ria Blokdyke, did not attend the wedding, because her daughter only told her about it afterwards.
"She told me on my birthday... it was a big secret I think," she told Fairfax.
"All her brothers and sisters were at my birthday. That's why she phoned me to tell me.
"The brothers and sisters didn't go to the wedding."
In 2012, Ewen Macdonald was found not guilty of murdering Guy, who was shot outside his rural property on July 8, 2010.
Macdonald was jailed for five years for other offences, including vandalising the farmhouse, where Guy lived with wife Kylee, killing 19 calves and burning down a 110-year-old building.
He was granted parole in 2015 with strict conditions, including electronic monitoring, a ban on visiting the North Island, a ban on firearms and a ban on communication with co-offender Callum Boe.
