Five other fragments have previously been found and identified as definitely or probably from the Boeing 777.
All of them were discovered thousands of kilometres from the current underwater search far off Western Australia's coast,where three ships carrying sophisticated equipment are scouring the sea floor for traces of the plane.
Australia's Transport Minister Darren Chester said two of the new pieces were found in Mauritius, with the other in Mozambique and were "of interest in connection to the disappearance of Malaysian Airlines flight MH370" .
"The Malaysian government is yet to take custody of the items.However, as with previous items,Malaysian officials are arranging collection and it is expected the items will be brought to Australia for examination," Mr.Chester said in a statement.
"There items of debris are of interest and will be examined by experts".No other details were given. The first concrete evidence that MH370 might have met a tragic end was when a 2m-long wing part known as a flaperon washed up on a beach on the French overseas territory of La Reunion in July last year.
