A 30-year-old man [1] was arrested and charged with the double murder of Brendon and Trina Cole.

The arrest follows a months-long investigation into a crime that shocked the Ruatiti community and left a couple dead in a rural area.

Police discovered the bodies of the two victims [1] in December 2025 [2] on Murumuru Road. The location is situated near Whanganui National Park in the Ruatiti area of Whanganui, New Zealand [1, 2].

Authorities announced the arrest this week, marking a transition from the search for a suspect to the formal legal process. The suspect remains unnamed as the case proceeds through the judicial system.

Detective Inspector Gerard Bouterey said the arrest represents a "significant milestone" in the investigation. He said the police are pleased to have this result for the families of Brendon and Trina Cole [2].

The investigation team focused on the remote nature of the crime scene on Murumuru Road. Police said the arrest is a significant milestone in the investigation into the couple’s deaths, and aims to bring justice for the families [2, 3].

“The arrest represents a "significant milestone" in the investigation.”

The transition from a cold case to a formal charge indicates that investigators have likely secured forensic or testimonial evidence linking the suspect to the December 2025 crime scene. By making an arrest five months after the discovery of the bodies, New Zealand authorities are moving toward a trial phase to provide closure for the victims' families in a high-profile double homicide.
