Police have confimed that a missing Christchurch woman had gang connections in Wellington, but say the focus of their investigation remains in Christchurch.
Tisha Lowry, 28, was last seen walking with a man on Wainoni Road after leaving a pub on 25 September.
Detective Senior Sergeant Virginia Le Bas has confirmed that she had connections with the Mongrel Mob in Wellington and that police have been making inquiries in the capital.
But Ms Le Bas says the investigation centres on Christchurch. Officers will search the Avon River.
The last known person to be seen with Ms Lowry is being urged to contact police.
Ms Le Bas says they want to speak to a man seen walking with Ms Lowry after she left the Bower Tavern.
He is described as dark-skinned, possibly Maori, of thin build, aged in his 20s or 30s, with dark, short hair.
Police discovered on Thursday that she went home and changed her clothes before heading out again.
Her family say they first became concerned for her safety when she did not make it to her grandfather's birthday on 26 September.
Police have completed forensic examinations of the house where she lived, nearby rivers and parklands and her partner's house.
Ms Le Bas says some items taken from the house are being forensically examined.
She says police are also following up about 10 possible sightings.
