Two pieces of debris found in Mozambique are "almost certainly from MH370", Australia's transport minister said Thursday, following analysis by technical specialists probing the missing Malaysia Airlines flight.

"The analysis has concluded the debris is almost certainly from MH370," Darren Chester said in a statement, adding that Malaysia's MH370 investigation team had found that the pieces were consistent with panels from a Malaysia Airlines Boeing 777 aircraft.

"That such debris has been found on the east coast of Africa is consistent with drift modelling performed by (national science body) CSIRO and further affirms our search efforts in the southern Indian Ocean."

Australia is leading the search for MH370 in the Indian Ocean, where the Kuala Lumpur-Beijing flight was believed to have diverted when it disappeared on March 8, 2014 carrying 239 passengers and crew.

The hunt is expected to wrap up in June-July if the aircraft is not found in the target zone of 120,000 square kilometres (46,000 square miles).

"The search for MH370 continues," Chester added.

"There are 25,000 square kilometres of the underwater search area still to be searched. We are focused on completing this task and remain hopeful the aircraft will be found."

No crash site has been found and so far only a wing part from the Boeing 777 recovered from a beach on the Indian Ocean island of Reunion has been linked to MH370.

Specialists, including from Australia and Boeing, have been conducting examinations alongside the Malaysia team in Australia on the two items after they were found earlier this month in Mozambique.

Australia's Joint Agency Coordination Centre (JACC) said on Wednesday that Malaysia was also working with South African officials to arrange for the examination of another piece of debris "suspected to be the cowling from an engine".

South African authorities said Tuesday the fragment was picked up near Mossel Bay, a small town in Western Cape province.

Mossel Bay is more than 2,000 kilometres (1,250 miles) from Vilankulo, the Mozambican resort where one of the pieces being examined in Australia was found.

The Malaysia Airlines' Boeing 777 with 239 people aboard disappeared during a flight from Kuala Lumpur to Beijing on March 8, 2014.

Search efforts are being conducted in southern Indian Ocean.

The first piece of debris was recovered from Mozambique while the second piece, also from that country, had been brought to South Africa by the family who had discovered it.

A Malaysian team comprising DCA, Malaysia Airlines and the MH370 Safety Investigation Team retrieved the latter from South African authorities.
