Jamie Slater Found Responsible for Murdering Whatitiri Whakaruru at Hāwera Accommodation Complex

A tragic incident that began with a night of casual fun at a boarding complex in Hāwera, South Taranaki, turned fatal when Jamie Slater, also known as Jamie Shippey, stabbed 26-year-old Whatitiri Whakaruru in the heart with a chef's knife.

Witnesses, including Keremeta and Hori, intervened, with Hori grabbing the knife and throwing it to the floor before assisting Whakaruru. Emergency services were called and arrived shortly after, but Whakaruru could not be revived.

The report outlined Slater's significant behavioral and cognitive deficits, including impulsivity, emotional dysregulation, and limited insight. Slater was deemed a high risk of reoffending and was ordered to be detained in a psychiatric hospital as a special patient.
