A man who suffered two strokes and could no longer walk or clean himself was left alone without food for hours in a house by his wife, his sole carer, a jury has heard.
Malia Unalotokipea Li denies causing Lanitola Epenisa's death from sepsis, a blood infection brought on by infected sores '"all over his body", some so deep muscle and bone were exposed.
The mother of two is on trial for manslaughter at the High Court in Auckland, almost five years on from his death in October 2016 in Māngere.
Epenisa died sitting in his own encrusted faecal matter, with maggot pupae embedded in his hip and surrounded by bags of his soiled clothes and a nest of mice, the Crown alleged.
A relative of Epenisa visited him while he and his family lived at a Tongan community-operated home on Vine St in Māngere.
Paealata Laukaupo'uli said her son had to climb through the window because they found him locked inside alone when they came to visit.
Epenisa shouted through the window that he had not eaten.
"Another time I went to visit Epenisa, I knocked on the door and no one was there, I rang Malia and she came back," she told the courtroom.
"When the door was open Epenisa was shouting from the bedroom and he said to her 'Since you've left this morning I haven't eaten'."
Because of Tongan custom, Laukaupo'uli did not want to interfere, she said.
She offered to help Li find a more suitable home for her husband's needs but it never eventuated, she said.
On one visit Laukaupo'uli claims Epenisa asked his wife to go to the toilet. She told him to wait until their daughter arrived home.
"Epenisa said he was desperate to go to the toilet. Malia said just wait."
Malia then "led" him to the bathroom during which it appeared "an accident happened", the courtroom heard.
When their daughter arrived home she was seen mopping the floor and giving him a bath.
Laukauo'uli agreed under cross examination it is "tapu" in Tongan culture for daughters to undress their father, but she did not talk to Malia or anyone else about her concerns.
Laukauo'uli often spoke to Malia over the phone about Epenisa's wellbeing when the family moved out of the community house and into a home of Malia's relative.
"She told me she often leaves Epenisa with her cousin. I asked her: 'How does he go to the bathroom?' and I was told the cousin takes him."
Malia said Epenisa did not want to go to a rest home.
Epenisa missed doctor's appointments and family gatherings, Laukaupo'uli claimed.
"There was one appointment my daughter was going to take him to, but it didn't happen.
"My son really wanted to see Epenisa on the day of his wedding. He didn't come."
Under cross-examination Laukauo'uli confirmed she knew Malia had been to hospital twice for her own medical issues.
A committee member who helped to maintain the Vine St community house would visit "more or less every day".
Siupeli Moala said Epenisa would sometimes be left alone in the house during the day.
The committee asked for Epenisa's family to move out of the house when they wanted to carry out renovations. The family, who had been living there for two years, moved out in January 2016.
They shifted into a house owned by Li's relative on Kivell Close in Māngere.
It was here a prayer group from the family's church came to pray for Epenisa in June 2016, a relative of Li told the jury.
Kalolaine Faleafa said they stayed for around 15 minutes and said Epenisa was leaning in his chair and talked very slowly.
A second time they visited to pray, Epenisa's daughter said he was sleeping and turned them away. The group did not step inside the house, Faleafa said.
It's the third day in the trial before Justice Wylie.
