The MH370 family support group is upset with the government for the lack of communication with the next of kin on their plight to find out the whereabouts of the missing flight.

The group has urged the government to be open about the offer and their decision-making process.

Group's spokesperson Grace Nathan said: "One consistent theme since MH370 disappeared on March 8, 2014 is their lack of communication with the next of kin.

“Time and time again we have asked to be a made a part of the process. Instead, we are treated as incidental to it. Malaysia has made no attempt to repair or improve the lack of faith, or trust that has developed over the last three-and-a-half years."

The final report on the underwater search carried out by Australia is due in September.

“We believe that their earlier recommendation that the newly more narrowly defined search area be searched will carry through into this final report. We hope that Malaysia makes its decision by then so that we do not incur any more delay which will result in further decay of evidence that may lead to solving what is dubbed as the greatest aviation mystery of all time,” she told Malaysiakini.

“We hope Malaysia will honour its promise, to the world, to find this plane and bring my mother and 238 other passengers and crew on board home."

In their official statement released this morning, the group commented: “The US seabed exploration firm Ocean Infinity and the government have confirmed that there is a proposal to search for MH370. Why hasn’t Malaysia accepted this win-win offer?”

Especially since the transport minister had repeatedly stated that lack of funds has never been an issue vis-a-vis the search for MH370, they added.

"It has been more than four months now since Ocean Infinity first made the offer to carry out the search with a fee payable contingent upon success. We believe this offer should be accepted without further delay.

“We call upon the government to share with Voice 370 - the Association of Families of Passengers on MH370, the aviation industry and the flying public. When is a decision on the proposal expected and the evaluation criteria being used for this process; the details of the proposal from Ocean Infinity, including what constitutes success and qualifies for a fee payable; and, should the search be successful, what are the plans for recovery.”
