An arrest has been made in the murder investigation of a person found buried in a shallow grave in the central North Island.

Following the discovery of the remains near Tongariro in March, police launched a homicide investigation called Operation Quattro.

Yesterday afternoon a 29-year-old man was arrested by Waitemata Police.

He has been charged with accessory after the fact to murder and appeared in the Waitakere District Court this morning.

Formal identification of the deceased is ongoing, however police believe the murder victim is Bao Chang Wang, also known as Ricky Wang, whose whereabouts had been unaccounted for since 2017.

Detective Inspector John Sutton says the arrest is a result of the hard work and dedication by the investigation team over an extended period of time.
