The 80-year-old Chinese woman who was attacked in her Manurewa home this week has died.
Police have launched a homicide inquiry as they hunt for a man linked to Wednesday's home invasion, which left the woman, Yin Ping Yang, battered and unconscious in her Manurewa home.
She was in serious condition in hospital for several days before her death.
The woman, who had been bundled into a wardrobe, was found by her shocked son at her Saralee Drive home, a short distance from the liquor shop where Navtej Singh was fatally shot a week ago.
Police said it appeared to be a random attack on the woman who lived at the address with her son and grandchildren but was alone at the time.
The woman was found when her son returned by home about 10pm on Wednesday but the attack was thought to have occurred about 5.30pm.
Detective Inspector Mark Gutry from the Counties Manukau police said it was not known how the intruder entered the house and the first the woman was aware anything was wrong was when a hand was place over her mouth and she was assaulted.
She was forced into a wardrobe but managed to get free and collapsed unconscious on the living room floor where she was found by her son.
He initially thought she had fallen over and drove her to hospital where she was found to have internal injuries, including broken ribs.
When she regained consciousness the next day the woman said she had been attacked and police were informed. She was not believed to have been sexually violated.
Mr Gutry said there was no obvious motive for the attack.
"This is an assault on an 80-year-old woman who couldn't fight back and so we'd really like to get hold of this person before he hurts anyone else," he said.
