A former Fiji citizen who murdered his former partner has been sentenced to life imprisonment by the New Zealand court.

42-year-old Rohit Deepak Singh was found guilty for killing 24-year-old Arishma Chand in her home in Manurewa, South Auckland.

The 24-year-old mother who was also a former Fiji citizen was stabbed to death in November 2017.

The Crown’s case was that Singh was a jealous ex-boyfriend who became infatuated with Chand during a brief sexual relationship in 2016.

The pair met through Chand’s father, who had worked with Singh for a decade in Fiji.

Chand who had a daughter from a previous relationship entered a sexual relationship with Singh and hid it from her parents.

She later got pregnant, had an abortion and ended their relationship.

The Crown prosecutor informed the court that Singh refused to accept the break-up and began stalking her.

Chand was found by her parents in a pool of blood on her bedroom floor in their family home.

Chand’s parents say their lives have been torn apart and their three-year-old granddaughter is now motherless, constantly asking where her “mummy” is.

Singh will have to spend at least 19 years behind bars.
