Bay of Plenty Police are looking for 35-year-old Genevieve from Pahoia.
Her family and Police have concerns for her well-being.
Genevieve was last seen at her home by her family at about 4.30pm yesterday.
She may have hitch-hiked from Pahoia to Tauranga.
A woman fitting her description was seen getting into a silver-coloured vehicle, similar to a Honda City, near the intersection of Pahoia Road and SH2 between 4.30pm and 5pm yesterday.
A witness also believes they saw her talking to a person in a light brown-coloured Ford Territory on SH2 yesterday afternoon.
