KEY POINTS:
The disappearance of a Christchurch woman has raised fears that she has met the same fate as other young women in the city in recent months.
Tisha Lowry, 28, was last seen a week ago in the eastern suburbs of Christchurch after visiting a bar with her grandfather and opting to walk home. She has not been in contact with her family since.
When last seen, she had only the clothes she was wearing, including a Chicago Bulls jacket and jeans, having left her handbag and cellphone at home.
Police say they have "grave fears" for Ms Lowry, and her mother believes something is "seriously wrong".
Her disappearance comes just a few months after Christchurch schoolgirl Marie Davis, 15, disappeared and her body was found in a river near Christchurch. Dean Stewart Cameron, 38, is charged with her rape and murder.
Last November, 20-year-old deaf woman Emma Agnew went missing and her body was found concealed in scrub north of Christchurch.
Liam James Reid is to stand trial next week for Miss Agnew's rape and murder.
Detective Senior Sergeant Virginia Le Bas, who led the investigation into the disappearance of Marie Davis, said foul play had to be considered in the case of Ms Lowry.
"The fact that no one has heard from her ... it's unusual, and it leads you to think something odd has gone on."
Ms Lowry's mother, Tanya Lowry, told the Press newspaper that she feared the worst as it was uncharacteristic for her daughter not to have been in touch for so long.
