The man, who goes by just Akash, displayed “cruelty, brutality and callousness” in murdering 22-year-old Gurpreet Kaur, Auckland High Court judge Matthew Palmer said.
The judge said the pair were secretly dating for 12 months but Akash, 24, snapped on April 7 this year when Kaur told him the baby was not his and she wanted to end the relationship.
High on methamphetamine, he stabbed her 29 times and dumped the body in roadside bushes south of Auckland.
He initially pleaded not guilty, arguing the stab wounds were self inflicted, but admitted his guilt in August, four months after being arrested.
Palmer said the fact that Kaur was 7 to 10 weeks pregnant exacerbated the crime and made her death even more painful for her family.
“Not only did you murder Gurpreet Kaur and deprive her family of her existence, but you deprived her and her family of the potential of another life,” the judge said.
Akash was sentenced to life with a minimum of 17 years behind bars
