Christchurch police say it is "disappointing and frustrating" that the partner of missing woman Rowena Walker will not assist with investigations into her disappearance 10 months ago.
Rowena Walker went missing from a Burwood address in Christchurch on June 15 2025, and there had since been extensive searches and appeals for information about her including throughout Christchurch's red zone.
Today is her 40th birthday.
Inquiries have since led officers to believe that "on or around August 15, 2025, Rowena was the victim of foul play and is no longer alive".
Detective Senior Sergeant Jo Carolan said Walker's partner at the time has so far declined to assist police with inquiries.
"No person can be compelled to speak with police under any circumstances, and it is that person’s right to maintain his silence," she said.
"However, as the last person known to have seen Rowena alive, his assistance is crucial to the investigation, and it is disappointing and frustrating that he is unwilling to assist us."
"I would strongly urge him to reconsider and do the right thing by Rowena and her family," Carolan said.
Carolan renewed pleas for information, saying that no digital footprint and no verified sightings of Walker had been reported in the past 10 months.
"This absence of contact is deeply concerning for investigators and her family."
"The investigation has indicated that there is someone in the community who knows what happened to Rowena, and it’s time for them to step up and talk to Police.
"Rowena has family, including young children, who deserve answers about what has happened to her."
Police urged anyone with information they think may be relevant, no matter how big or small to get in contact online, by calling 105 or anonymously through Crime Stoppers on 0800 555 111.
