Malaysia's acting transport minister, Hishammuddin Hussein, has said that the search for Flight MH370 has shifted 1,100km (684 miles) north-east of the previous zone.
Mr Hussein said the new search area had been defined after previous information was re-examined and refined.
It is now believed the plane was travelling faster than earlier estimates, thus using more fuel.
The Beijing-bound airliner disappeared on 8 March with 239 people on board.
