MH370 Kiwi widow: 'We'll never stop searching'

The wife of a Kiwi-born man missing aboard flight MH370 says she and the relatives of other passengers will never stop searching for the truth.

A three-year search for the Malaysia Airlines flight was called off on Tuesday, less than a month after experts identified a new area they believed contained the aircraft.

Danica Weeks, whose New Zealand-born husband Paul is among the missing, criticised authorities for cancelling the search.

Mr Weeks, 39, moved to Perth after the 2011 Christchurch earthquakes and was on his way to start a new fly-in fly-out job at a Mongolian mine.

"It's their plane, their responsibility, they're the ones that promised they would bring them home and now they're just giving up," Mrs Weeks said.

"If Malaysia thinks it's just going to disappear on them, then they've got another thing coming.

"I'm not going to leave him out there or wherever he is, we're not going to leave our loved ones out there."

The Voice370 support group for victims' families has also called on the public and aviation authorities to pressure Australia, Malaysia and China into resuming the search.

The MH370 Tripartite Joint Communique from the three countries said they remained hopeful "new information will come to light and that at some point in the future the aircraft will be located".

Flight 370 lost contact with air traffic control on March 8, 2014 early in its flight from Kuala Lumpur to Beijing with 239 passengers and crew aboard, and is regarded as one of the greatest aviation mysteries.
