Paul Weeks from New Zealand, was on board Flight MH370 on his way to Mongolia to start a new job.
Mechanical engineer Paul Weeks, was on the plane that disappeared with 227 passengers and 12 crew on board.
Originally from New Zealand, Mr Weeks moved his young family to Perth, Australia, in 2011 to make a new start after their home in Christchurch was devastated by a series of earthquakes.
He left his wedding ring and watch with his wife and children as keepsakes in case something happened to him.
His wife Danica told the newspaper he had left his wedding ring and watch with her to give to their sons Lincoln, 3, and Jack, one, when they married.
She said: "Paul said 'If something should happen to me, then the wedding ring should go to the first son that gets married and the watch to the second'."
Mrs Weeks said she is praying for a miracle.
"I can't give up hope," she said.
"I would love him to walk through that door, hold him one more time."
A 100-nautical mile radius of the South China Sea is being searched for any trace of the plane, which disappeared on Saturday.
At least 10 countries are taking part in the search, which involves 40 ships and 34 aircraft.
