Fears are growing for the safety of a Christchurch woman who hasn’t been seen since September 25.

Inquiry head Detective Senior Sergeant Virginia Le Bas, of New Brighton CIB, said Tisha Lowry, 28, was last seen by a family member about midday last Thursday in the Hampshire Street area of the suburb of Wainoni.

Family reported her missing on Sunday.

Lowry had gone to a hotel in the Wainoni area with her grandfather about 11am.

While her grandfather, with whom she lived, stayed for a few beers, Lowry set out to walk home.

“Tisha … hasn’t been in contact with her family or friends since that time,” Le Bas said on Wednesday.

“It is logical that we obviously have grave concerns for her safety.”

Le Bas said she was fairly confident that Ms Lowry, who moved to Christchurch from Porirua about a year ago, had a Red Chicago Bulls jacket with her when she was last sighted on Thursday, and was probably wearing jeans and white sports shoes

Police were currently speaking with family members and other people Ms Lowry knew, including her 48-year-old boyfriend of five years, who TVNZ reported was a former gang member.

Lowry’s mother, Tanya, was reported as saying the couple had a sometimes difficult relationship.

“Today essentially we’ve been speaking to her family, and speaking to neighbours in the area where she’s been living and generally gathering and collecting some background information into her activities and movements,” Le Bas said.

“At this time we haven’t heard from her and we haven’t got any location of her.”

Le Bas said the longer Lowry remained missing, fears for her safety would grow.

She said police wanted to hear from anyone who might have some knowledge or clues as to her whereabouts.

Tanya Lowry pleaded for her daughter’s return. She said Ms Lowry had left her handbag, cellphone and other personal belongings at home, which raised fears.
