IT was a day in December last year that started like any other for Neil John Hinkley.
The 56-year-old ordered a new pair of glasses from Izzard's Optometrists at Umina Beach on the morning of December 19 and at 10.45am, began the three-kilometre walk to his home in Memorial Drive at Ettalong Beach.
About 11.15am, his wife, Myree, called and Mr Hinkley said he was walking up Ocean Beach Road still headed for home.
Then - within the next few hours - something strange happened.
Mr Hinkley, who his family said was suffering from depression, vanished without a trace.
When Mrs Hinkley, who was on her way home from work in Sydney, called again about 6pm, there was no answer.
Family and friends have not seen or heard from Mr Hinkley since and despite a number of unconfirmed sightings and ties to towns in northern NSW, he remains missing.
Mr Hinkley will feature on NSW posters for 2013 National Missing Persons Week, which launched in Sydney yesterday with the focus of watching for warning signs in at-risk people before they disappear.
Mr Hinkley's wife, son and daughter attended the launch and remain very concerned for his welfare.
"We do believe that there's a chance he's out there somewhere," Mrs Hinkley said. "I hope he knows and remembers how much he's loved and needed by myself and all of the family."
Choking back tears, son Matthew Hinkley described his father as an "honest, down-to-earth bloke".
"We all love you, from the Hinkley family," he said.
Photographs of Mr Hinkley and a recently located 14-year-old girl are currently being promoted on billboards, bus stops and train stations throughout the state.
Neil John Hinkley is described as being of Caucasian appearance, about 175-centimetres tall, with a medium build, brown hair and blue eyes.
Police said he was last seen wearing beige shorts and a Hawaiian shirt.
Missing Persons Week began yesterday and will run until August 3.
