A piece of aircraft debris found in Tanzania is "highly likely" to be from missing Malaysia Airlines flight MH370, Australia's Transport Minister Darren Chester says.
The wing part was brought to Canberra for analysis after it was found by locals on Pemba Island off the coast of Tanzania last month.
"It is highly likely that the latest piece of debris being analysed is from missing Malaysia Airlines flight MH370," Mr Chester said in a statement.
"The experts will continue to analyse this piece to assess what information can be determined from it."
Flight MH370 disappeared in March 2014 with 239 passengers and crew on board shortly after taking off from Kuala Lumpur bound for Beijing.
Investigators have confirmed a piece of plane debris found on the French island of Reunion in July 2015 as being part of MH370.
They have said several other pieces of debris found in Mozambique, South Africa and Rodrigues Island, a territory of Mauritius, are likely to be parts of the missing plane.
A search for the Boeing 777 has been going on in the Indian Ocean for more than two years but no sign of the main wreckage has been found.
Australia is leading the hunt for the missing plane in the southern Indian Ocean some 2,600 kilometres off its west coast capital of Perth after satellite data indicated the plane went down somewhere in that remote and stormy area.
Mr Chester said the combing of the 120,000 square kilometre search zone was expected to be finished by December.
"We remain hopeful that the aircraft will be located in the remaining search area," he said.
Malaysia, China and Australia said last week the search would be suspended if the aircraft was not found in an area now being searched.
