Samoa Airways is scheduled to take delivery of the Max 9 in April.
However, the Minister of Public Enterprises Lautafi Selafi Purcell has told Newsline Samoa that they cannot afford to do that now.
His statement came after the weekend crash of an Ethiopian Airlines Max 8 which resulted in the deaths of 157 people.
Five months earlier a Lions Air Max 8 also crashed, killing all on board.
Lautafi has shared his safety worries about the new aircraft with Samoa Airways.
European authorities have suspended flights involving both the Max 8 and Max 9 planes.
