Police are urging Flaxmere 42-year-old Ri Nikora to come forward and speak to officers investigating the death of former Flaxmere woman Kathleen Kawana.
Kawana's body was found in a Ngarimu Hill property, near Ruatoria, on August 3.
The property recently changed hands and the body was found by the new owners who had gone to have a look around, Detective Senior Sergeant Ben Quinn said.
Nikora has not been in contact with family in several weeks and police believe he may be able to provide information which may help the investigation in the death of the 46-year-old.
Kawana's family paid tribute to her on Tuesday as a loved mother of eight children.
