It has now been a week since 20-year-old Emma Beattie went missing in Canterbury.
Ms Beattie was last seen on Friday night at her home in Fernside around 11pm just outside the town of Rangiora, 30km north of Christchurch.
She has not been in contact with friends or family since.
Police are continuing their search efforts this morning and remain focused on the Ashley River area and properties of interest.
Yesterday, specialised dog squads were brought in to help search for the missing woman.
Police say they are very concerned for her wellbeing.
Emma has long blonde hair, is about 5'7" and is believed to be wearing orange and black Nike shoes.
She may also be carrying a small brown backpack with cream-coloured rope straps and may have had some Beats headphones with her.
