Police say they have reached a "critical point" in their search for a missing Northland mother.
Despite extensive investigations since mother of two Bridget Simmonds, then 42, was reported missing on March 6 last year, police have been unable to find her.
But new information from the public has resulted in police carrying out searches under warrant and setting up a 50-strong investigation team at Wilson Rd, Parakao, 40km west of Whangārei yesterday.
Today police narrowed their search area to one of these properties along Wilson Rd they searched yesterday, a statement said.
Detective Senior Sergeant John Clayton said police have reached a critical
point in their investigation, but were not able to provide further information for operational reasons.
