But the Australian Transport Safety Bureau cautioned that the drift analysis by Australian science agency CSIRO is based on French satellite images of "probably man-made" floating objects without evidence that they were from Malaysia Airlines Flight 370.
But the locations could provide potential starting points to search within a 25,000-square-kilometre (9,700-square-mile) expanse identified by a panel of experts in November as the most likely resting place of the Boeing 777 and the 239 passengers and crew on board.
Malaysia, China and Australia agreed to suspend the deep-sea sonar search in January after 120,000 square kilometres (46,000 square miles) of seabed were combed without finding any trace of Flight 370.
The new analysis is based on French military satellite images gathered on March 23, 2014, two weeks after Flight 370 mysteriously veered far off course during a flight by Kuala Lumpur, Malaysia, to Beijing and were taken near the original underwater search zone.

The CSIRO then investigated where the objects might have originated before drifting for two weeks. The CSIRO identified three potential crash sites, 35.6 degrees S, 92.8 degrees E; 34.7 degrees S, 92.6 degrees E and 35.3 degrees S, 91.8 degrees E.
"So that is a way of potentially narrowing down the search area with the very important caveat that, of course, we can't be totally sure that those objects seen in the images are actual pieces of plane," CSIRO oceanographer David Griffin said.
The Australian bureau's Chief Commissioner Greg Hood said in a statement: "Clearly we must be cautious" of the lack a definite link to Flight 370.
Malaysia, China and Australia have decided that the search will remain suspended unless new evidence pinpoints the wreckage's whereabouts.
But seabed exploration company Ocean Infinity, based in Houston, Texas, said last week it has offered to launch a private search for the Malaysian-registered airliner.
