A Christchurch woman allegedly cut her partner's throat and stabbed him repeatedly - stopping only when the blade became lodged in his spine.
She then dragged his body and hid it in dirt and leaves while she cleaned the scene and moved out.
Martin Berry's body then lay concealed in his back yard for several weeks before Rena Joyce walked into a local police station and told them she had "accidentally manslaughtered him".
The alleged murder followed a series of earlier assaults on Berry - who told friends he was scared of Joyce and feared for his safety but was too "ashamed" to speak up and ask for help.
He had a protection order in place against her when he died.
Despite her claims that Berry's death was accidental, Joyce was charged with murder.
The 56-year-old is defending that charge in a trial in the High Court at Christchurch before Justice Jonathan Eaton and a jury.
Police allege Joyce murdered Berry at his home on Main North Rd in Papanui shortly after the troubled couple returned home from a lunch with his family in late December.
His decomposing body was not discovered until mid-January after Joyce went to the police.
Thirty-one witnesses will be called during the trial - set down for two weeks - including police, forensic experts and family and associates of both Berry and Joyce.
This morning a jury was empanelled and underwent rapid antigen testing before they were sworn in.
This afternoon Justice Eaton addressed them briefly about their role and court processes before the Crown and defence delivered their opening statements.
The Herald can now publish details of Berry's death which until today could not be reported.
Crown Prosecutor Penny Brown told the jury that Joyce killed Berry by stabbing him in the neck and cutting his throat.
She then "dragged" him outside and "partially buried him", then "left him to rot".
Brown said the alleged murder was "the fatal climax of an escalation of domestic violence" that Berry suffered at the hands of Joyce.
Joyce had been in a relationship with Berry for about five years and lived with him at his property on Main North Rd.
On December 30, a Tuesday, they went out for lunch at a local Indian restaurant with Berry's brother and his partner.
Over the next 15 days, Joyce went to the supermarket a number of times purchasing wine, cleaning products and rubbish bags.
She then proceeded to clean the house and attempted to conceal the bloody crime, Brown told the court.
It is alleged that Joyce then cleared all of Berry's personal property, clothing and furniture out of the house - discarding items into various rubbish bins in the neighbourhood that were collected over the next few days.
Joyce then packed up her own property and moved out, leaving Berry's body hidden in the back yard.
On January 19 last year she walked into the Christchurch Central Police Station and told staff Berry was dead.
She told officers: "I have buried my partner in the back garden."
His statement was brief and he said he would give a much more in-depth address later in the trial once he had heard the Crown's full case against his client.
It is not yet known if Joyce will give evidence in court, or call witnesses.
The jury then heard from one of the officers who found Berry's body.
Constable Fraser Woon said he was sent to carry out a welfare check on Berry at his home soon after Joyce presented at the police station and confessed to killing him.
He said he went to the backyard to look for any disturbed ground or evidence of Berry's body.
Woon and a colleague found a "mound of vegetation… that appeared to be a compost heap".
