KEY POINTS:
Police have issued 4000 flyers seeking information about the disappearance Christchurch woman Tisha Lowry as the investigation enters its third week with few clues to her whereabouts.
Detective Senior Sergeant Virginia Le Bas said 4000 flyers were being distributed to family, friends, and Community Watch in the area she lived in and was last seen in.
The flyers are also on Christchurch city buses.
"Already these flyers have generated calls from the public," Ms Le Bas said.
"The inquiry team is following all this information up."
Ms Lowry disappeared without a trace on the morning of September 25, after leaving the Bower Tavern in suburban Aranui to walk to her grandfather's home nearby.
She was reported missing by her family on September 28.
Ms Lowry and her 48-year-old boyfriend moved to Christchurch a year ago from Porirua and had been living together in the Aranui and Kaiapoi areas.
Recently Ms Lowry had been living with her grandfather "to have a little bit of space" from her boyfriend.
Ms Lowry's personal belongings, including her cellphone and handbag, were found at her grandfather's home.
Since her disappearance Ms Lowry has had no contact with family or friends and there have been no confirmed sightings of her.
