As police continue to hunt for missing Christchurch woman Tisha Lowry, her mother today made a desperate plea for information.
Ms Lowry, 28, went missing in the suburb of Aranui about midday a week ago. She was reported missing on Sunday.
Police hold grave fears for her safety.
Today Ms Lowry's mother, Tanya, said she had no idea what had happened to her daughter, but she hoped and prayed she would return.
Tanya Lowry believes there must be someone, somewhere who had seen Tisha last Thursday and she wants that person to come forward.
Today police carried out a scene examination at the house in Hampshire Street where Ms Lowry lived with her grandfather.
Ms Lowry had left her grandfather at a local hotel and walked home.
She was wearing a blue Abercrombie sweater and carrying a case of Double Brown beer.
Police believe she reached home because the sweater was found there and it was thought that she then changed into a red Chicago Bulls jacket.
Her grandfather saw nothing amiss when he got home and it was not until Sunday that she was reported missing.
Police said the scene examination would be difficult given the time lapse, but they were not looking for anything specific and it was just a routine examination.
Inquiry head Detective Senior Sergeant Virginia LeBas, of New Brighton CIB, said the time frame and lack of communication with her family raised grave concerns.
Ms Le Bas said the examination of Ms Lowry's home was "just part of regular policing practice".
"This was where we believe she was heading back to when she left her grandfather last Thursday so it is an obvious place to look for any information."
So far there had only been a limited response from the public, she said.
"We would like as much information as we can get, especially any sightings of Tisha. As time goes on we become increasingly concerned for her safety."
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.
Ms Le Bas said that recently Ms Lowry had been living with her grandfather "to be in a different location and to have a little bit of space".
Ms Lowry's personal belongings were found at home, including her cellphone and handbag.
