The discovery of human remains found in a shallow grave in the central North Island is now being treated as a case of homicide.
The remains were found on Rangipo Intake Road near Tongariro on Tuesday last week.
They are believed to be those of a Chinese man in his 30s who has not been seen since 2017, although formal identification is yet to be completed.
The examination of a property on McWhirters Farm Lane in Massey, west Auckland, was completed this morning.
The current occupants of the property have nothing to do with the investigation.
