Police say the disappearance of Rawene woman Barbara Moka is increasingly looking like foul play.
Police have boosted the inquiry's staff numbers and renewed their appeal for information.
The 32-year-old mother was last seen on Sunday June 9 and had attended a Tangi at the Te Piiti Marae, Omanaia, near Rawene.
Ms Moka and her partner, aged 43, had reportedly been involved in a motor vehicle crash in the early hours of Sunday, about 1am, not far from the marae.
Police have been told that they returned to the marae following the crash.
