Detectives looking into the disappearance of missing Christchurch woman Rowena Walker are holding a press conference this morning. 

Walker, 39, has not been seen since August 14 last year, when she was captured on CCTV on Bassett St, Christchurch. 

Speaking from the city’s residential red zone today, Detective Senior Sergeant Jo Carolan is giving an update to media. A livestream can be watched at the top of this article.

Carolan says Walker lived near the red zone that police will search today. Police want to ensure “no stone is left unturned”. 

“Even small finds could be crucial,” she said. 

Carolan said police cannot rule out foul play. 

Officers have executed a number of arrest warrants and say they have grave fears for Walker. 

It is the first time that the red zone has been searched since Walker disappeared eight months ago. 

The searchers will focus on areas of vegetation. 

Earlier this week, Carolan said police believed Walker may have been near the red zone when she went missing. 

A drone, boats and police ground crews have since scoured the area for Walker. 

“We believe Rowena went missing from Christchurch, as we have found no evidence she left the city before her disappearance,” Carolan said. 

“The day before, she told family she was living in Christchurch with a friend, indicating an intention to settle here. 

“This week, Police Search and Rescue, alongside Specialist Search teams, will be conducting land, water, and aerial searches in and around the red zone.” 

“Rowena’s last confirmed sighting was on August 14, when she was captured on CCTV in Christchurch on Bassett St with an associate,” she said.

Carolan said police have searched across the country for Walker. 

“We know she travelled often, and in our efforts, we have searched in several districts, including Waikato, Tasman and Canterbury,” she said. 

Walker has not been in contact with her children since she went missing, and her family are “desperately worried”, Carolan said.
