A man accused of fatally stabbing his ex-wife in a broad daylight attack in West Auckland had previously been conducting surveillance on her, a court heard.
Manchao Li, 65, denies murdering Zhimin Yang and breaching a protection order.
His trial started today in the High Court at Auckland before a jury with Justice Pheroze Jagose presiding.
It is alleged Li repeatedly stabbed his former partner - also known as Jennifer - in Massey on July 29 last year.
Crown prosecutor Nick Webby said Yang reported seeing Li loitering near her home on the evening of April 17, 2019, despite a protection order being in place.
"He shouldn't have known where she lived but somehow he did," Webby said.
The prosecutor said she told police: "I believe if Manchao knew where I lived he would kill me".
The following day police observed him in the area but he claimed he did not know where she lived and that he walked every evening on doctor's orders, Webby said.
Webby said there were "strange goings-on" at another address in Massey in the months prior to Yang's death.
Tenants at her son's house reported "suspicious things" happening on the property starting on May 28, 2019, when they noticed all the tyres on their cars had been slashed.
Next a car was tagged with red paint before a dead rat and then a dead pigeon were found in the letterbox, Webby said.
Yang met with a community constable and advised that she suspected Li was responsible for the damage "as a way to get to her".
Earlier Webby told the court that just after 8am on the day of her death Yang had left home to catch a bus on Westgate Drive.
"She didn't realise it at the time – at least not until it was too late – that she was being followed that morning by the man that would kill her," he alleged.
The Crown alleges Li stabbed her 12 times across her head, neck, chest, stomach and arms with a hunting knife that had been purchased the day prior.
The blows sliced into a major artery in her neck and a major vein in her body, Webby said.
The court heard several members of the public - including a nearby construction worker - rushed to help Yang.
Webby alleged the construction worker had seen Yang tackled from behind and dragged to a grassy area before her assailant pulled her hair back to expose her face to the attack.
Another witness described a man punching a woman on the ground as she screamed hysterically, the prosecutor said.
Efforts were made to resuscitate Yang.
"Her life was unable to be saved," Webby said.
"She died not far from where she had been waiting for her bus."
As people had neared, Webby said, Li left in his car but was followed by a member of the public who managed to block him with his own vehicle.
Li had a tendency of breaching the protection orders that were in place, Webby said.
He had become "obsessed" with exacting revenge – or "justice as he viewed it" – after a property dispute in which the court ruled in her favour, he said.
The Crown's timeline
The court heard Yang and Li married in China in 1997 before moving in 2001 to New Zealand where they purchased a property in Blockhouse Bay.
"Both contributed some money and took out a mortgage," Webby said.
The couple separated in 2005 and she moved to Avondale.
Shortly after that Li came around to her property and a "loud argument" ensued that sparked a police call, Webby said.
Another protection order was granted in early 2018 and on February 9 the police removed a number of weapons from Li's home, including air-rifles and five crowbars, Webby said.
