Search teams are scouring areas a missing Nelson woman was known to visit, police say.
Ann Sheridan, 48, was reported missing on Monday.
Her car and wallet were found at her home and her bank accounts had not been touched.
Police yesterday interviewed family and friends and completed a search of Ms Sheridan's home.
Senior Sergeant Grant Andrews said a number of recurring themes came out of those interviews which had led to identifying today's search areas.
