Police are hoping a leaflet drop will turn up new clues in the search for a missing Christchurch woman.
Emma Campbell was last seen buying petrol from the Shell service station on Riccarton Road at 5.30am on Saturday.
Family and friends helped in a search of a forestry area near Dyers Pass Road on Wednesday, but nothing of significance was found.
Police have organised the leaflet drop to houses in the suburb below the Port Hills valley where the 29-year-old's car was found.
They say they have been talking to a range of people connected with Ms Campbell and inquiries will continue on Thursday.
Police would like to hear from anyone who may have been in the Dyers Pass Road area on Saturday between 5.30am and 7.30am.
