Investigators are poised to release new information about the disappearance of Jessica Boyce in 2019.
Marlborough Police investigating the disappearance are encouraging people to watch tomorrow's Cold Case programme on TVNZ.
Detective Senior Sergeant Ciaran Sloan said "a large volume of information" has been worked through and "significant aspects of those inquiries" will be revealed on the show.
"The team remain focused and motivated to locate Jessica and to hold to account those responsible for her disappearance," Sloan said.
Boyce went missing from Renwick in Marlborough on March 19, 2019.
She was driving a red Holden Rodeo ute, registration BDG553.
After no contact from Boyce for two days, family members posted Facebook messages appealing to the public for help.
On March 22, 2019 at about 8pm, members of the public who had seen the Facebook post reported the location of the Holden Rodeo.
The vehicle was on the road leading to Lake Chalice in the Mount Richmond Forest Park.
Police began to receive anonymous information suggesting Boyce may have been the victim of foul play.
From that, patterns started to emerge and develop over time, police said, and homicide investigation Operation Largo was launched.
Anyone holding onto relevant information or knowledge of Boyce's disappearance is urged to contact the investigation team on 0800 COLD CASE (0800 2653 2273).
Watch Cold Case at 8.30pm tomorrow on TV1 or on TVNZ+
