Nearly four days after the disappearance of Malaysia Airlines Flight MH370, there's still no definitive trace of the Boeing 777 or the 239 people who were on board.
Two-thirds of the jet's passengers were Chinese. The rest were from elsewhere in Asia, North America, Europe, Australia and New Zealand.
Paul Weeks, 38, was one of two New Zealanders named on a passenger list for MH370. His wife, Danica Weeks, says she is praying for a miracle.
"I can't give up hope. I would love him to walk through that door, hold him one more time ... I see him everywhere in the house," she told the Nine Network.
"It's so hard, so hard. I mean we are praying for a miracle."
Weeks left Christchurch for Perth in 2011 with his wife and two young children in search of a better life after the earthquakes.
Mr. Weeks was en route to Mongolia for his new job with Transwest Mongolia. He emailed his wife before the flight to tell her he missed her and their sons Lincoln, three, and Jack, 11 months.
"He sent me an email saying he missed us, that we were his world, and that was the last I heard from him," she said.
Danica said on Sunday she was desperately waiting for news of him.
Weeks' older sister, Sara Weeks, of Christchurch, told Fairfax Media in New Zealand that family members were clinging to hope.
''At the moment we're all just here hoping to find something out. I think we're hoping that it landed somewhere nicely and he's sitting having a coffee. We don't know anything other than what we have seen on the television, but I think when you put two and two together... it's not looking good."
New Zealand Prime Minister John Key expressed his sadness over the aircraft's disappearance.
"This will be an almost unbearable wait for the families. Not knowing what has happened to the flight and their loved ones is an awful ordeal. While they will be hoping for a miracle, they will also be preparing themselves for the worst," he said.
"There is nothing I can say to alleviate their pain, but they should know we are hoping and praying with them."
