The family of missing Northland woman Bridget Simmonds have appealed for the public's help a year after the mother-of-two's disappearance.
Simmonds, 43, was reported missing on March 6, 2019, 11 days after her last confirmed sighting.
Police investigators have made multiple enquiries into the woman's disappearance, speaking to friends, family and associates, sifting through hours of CCTV footage, reviewing her bank transaction history and appealing to the public for information.
Despite the tireless efforts, Simmonds' whereabouts after February 23, 2019 remain unknown.
Simmonds' mother, Carol, has now issued a heartbreaking plea for the public to help her find her daughter.
"We really need closure, we miss her so much and not knowing what happened to her is very hard to deal with," Carol said in a statement.
"If anyone has heard anything or knows anything please let us know so that we can move forward and take the next step rather than constantly wondering all of the time."
On February 23, CCTV footage shows Simmonds making a bank transaction at an ATM after spending the night in Kerikeri with Carol. The two then travelled to Whangarei.
Carol last saw her daughter when she dropped Simmonds off at Countdown Regent on Kamo Road in Whangarei. The 43-year-old has not been seen in person since.
"We believe someone knows where she is or someone would have seen her in those days following February 23," Detective Senior Sergeant John Clayton said.
"We have been working closely with Bridget's family who are desperate for answers... they worry more and more about what's happened to her.
"Her family has had to heartbreakingly spend Christmas, birthdays and other family occasions without her and without knowing she is safe and alive."
The investigation into Simmonds' disappearance is still being treated as a missing persons' case by the police.
"We are determined to find out what happened to this mother, daughter and friend to so many people and bring her family and friends the answers they desperately crave," Detective Clayton said.
Bridget Simmonds was last seen wearing a dark singlet and has a large, distinctive tattoo of a fairy on her upper left arm.
