In her opening address, Crown solicitor Sarah McKenzie said there was no dispute about who killed Reedy or how — both parties agreed she was strangled in the motel room by her husband.
The question of the trial was about Fallowfield's intention and the Crown's case was that he murdered Reedy, she said.
Fallowfield and Reedy lived in Balclutha and they knew each other about a year before their wedding in April 2019.
Since then, police had attended six family harm incidents where Fallowfield and Reedy were "victims, aggressors, or offenders".
"Their relationship was not without issues," McKenzie said.
The first incident happened the day after they were married, when Reedy told the police Fallowfied had a gun in his possession but he did not have a licence for it.
At the time, he was charged and sentenced to three months' home detention and the judge placed him on six months of post-conditions release.
Police also attended another five incidents — which included an occasion where Reedy allegedly trespassed Fallowfield from the property on July 2019, and a complaint that Reedy had been raped by Fallowfield when she went to pick up some belongings at his house in December 2019.
Police had not laid any charges in relation to those matters, but on December 18, 2019, the Department of Corrections issued a non-association order to Fallowfield in relation to his wife.
During the lockdown, on March 25, Fallowfield obtained a relaxation on the order — he could contact Reedy by phone, attend Corrections appointments with her and go for walks with her.
Despite the order, McKenzie said it seemed Reedy and Fallowfield were living together.
"The defendant described their relationship during that time as the best they ever have been, so much so [that] on May 7, 2020, the defendant booked a motel room in Te Anau."
On the day that Reedy was killed, the couple checked into their accommodation and headed to the township, where they walked while holding hands and bought some wine.
After returning to the motel, at 3.22pm, Reedy posted two pictures on her Facebook page, one with her husband and the other alone while holding a glass of sparkling wine.
She wrote as the caption "Cheers from Te Anau", the court heard.
Fallowfield has told the police at some stage Reedy changed and they had a "bit of a tiff" in respect to a previous rape allegation made by Reedy against Fallowfield.
"He said they didn't yell or anything but Shirley Reedy threatened to have him up for rape again. He says he pleaded with her not to and that she started to yell 'rape', 'rape'."
Fallowfield told the police he felt dirty and he just snapped.
"The defendant describes going over to Shirley Reedy and straddled her with a leg on either side of her torso, putting his hands around her throat."
The jury heard when he removed his hands, she laid limp.
"In his interview, he says he cuddled her, told her he loved her and he was sorry."
McKenzie said the pressure applied to Reedy's neck was not minimal and Reedy was being treated with medication for schizophrenia at the time of the crime.
This is not a case where the defendant did not appreciate what he was doing and the very real consequences of his act, she said.
Defence counsel Katy Barker told jurors her client did not dispute that he killed his wife, nor the mechanism of her death.
"He is responsible and should be held responsible."
At the beginning of the trial, Fallowfield denied the murder charge, but told the registrar he pleaded guilty to manslaughter.
Barker said Fallowfield didn't intend to cause any bodily injury likely to cause death.
Much of the evidence presented in court was accepted by both parties, but the challenge for the jury was the interpretation of it, she said.
Barker said the Crown would not be able to prove, without reasonable doubt, what the defendant's state of mind was at the time of the offending.
"The defence's case is that Mr Fallowfield just wanted his wife to be quiet ... He did not intend to kill her," she said.
The trial before Justice Doogue continues tomorrow.
The Crown will call 19 witnesses during the two-week trial.
