Papua New Guinea's national carrier says it has full confidence in Boeing, despite dozens of airlines grounding its 737 Max planes over safety concerns.
Air Niugini also maintained it will still take delivery of four 737 Max 8 planes over the next two years, following their purchase in 2016.
The still unexplained accident, which killed all 157 on board, followed a Lion Air crash in Indonesia in October which killed all 189 people on board.
Air Niugini managing director Alan Milne said he's looking forward to introducing the new aircraft to the fleet.
Two of the Max 8s will be delivered next year and the other two in 2021.
EMTV reported Mr Milne saying the airline was monitoring the situation closely and was being kept "in the loop" by Boeing.
"The investigations for the Ethiopian accident are still ongoing so until those are completed, we won't really know what the cause of it is," Mr Milne said.
"But we're certainly sure that if there are any findings or recommendations from that investigation that will all be fully incorporated prior to the aeroplanes being delivered to us."
