The Hevilift Twin Otter aircraft came down near the capital Port Moresby on Saturday with nine people on board, the ABC reports.
The two pilots - including an Australian - and one passenger were killed in the crash. Another passenger died later. The conditions of the remaining passengers is not yet known.
PNG Accident Investigation Commission chief executive David Inau said the cause of the crash was not yet known.
"It's too early to say until [investigators] come back from the accident site."
A police spokesperson could not confirm reports the passengers included missionaries.
More than 20 planes have crashed since 2000 in PNG, where the rugged terrain and lack of internal connecting roads makes air travel crucial for around 6 million citizens.
