Detective Sergeant Trevor Beatson (Kaitaia) said last week that police had been working closely with Ms Scott's family to identify lines of inquiry, and he noted the distress her disappearance had caused for her partner, siblings and parents.
"They have been very patient, but as time moves on they are becoming more and more anxious," he said.
"We have continued with our inquiries into Leeann's disappearance, and committed significant resources to those inquiries, but are still looking for answers as to where she is and what has happened. Given the passage of time, with no contact or sightings since December 12, we obviously fear the worst for her."
Detective Sergeant Beatson could not be contacted yesterday, and it was not clear what avenues, if any, might remain open in the search for her.
Anyone who has any information, no matter how insignificant it might seem, is once again asked to contact the Kaitaia police on (09) 408-6500, or, anonymously, Crimestoppers on 0800 555-111.
When last seen Ms Scott was wearing a bright orange Northface 'Summit' hooded rain jacket, black exercise-style pants and creamy/brown Nike walking shoes.
