A 20-year-old woman who stabbed a Christchurch woman to death at a party will spend at least 10 years behind bars.
Katrina Epiha has been sentenced to life imprisonment at the High Court in Christchurch..
During an alcohol-fuelled rage, she fatally stabbed 32-year-old Alicia Nathan, and threatened to kill another at an Avonhead property in August 2017.
The victim's father, Paul Robinson, told the court he had video-called his daughter just 20 minutes before her death.
He says Epiha robbed Nathan's three-year-old son of laughs, cuddles and a future with his mother.
