Possible wreckage from missing flight MH370 was found in Pemba late last week.
Initial reports suggest that the debris is possibly from a Boeing 777, which is the same aircraft as flight MH370.
The Malaysian Airlines flight carrying 239 passengers and crew disappeared after veering off-course on a flight from Kuala Lumpur to Beijing in 2014.
The acting chief accidents investigator at the Tanzania Civil Aviation Authority (TCAA) says they can not be one hundred percent sure yet if the pieces belong to the lost plane, and are currently waiting on their Malaysian counterparts to join the investigation.
More debris found washed ashore on Madagascar earlier this month has yet to be examined.
