Dozens of body bags containing remains have been recovered from the crash site.
The Lion Air Boeing Co 737 MAX, which only went into service in August, crashed on Monday into the Java Sea.
Lion Air ordered as many as 218 units of the Boeing 737 Max 8 for its fleet, making it the first in Indonesia to operate the plane which made its factory maiden flight in 2017.
Syaugi also said on Saturday that a sonar locator had detected "low ping signal", which could be from the cockpit's voice recorder, also known as a black box.
Lion Air has claimed a technical problem was fixed after Sunday's flight.
Debris is seen on the sea bed in the search area for Lion Air's flight JT610 airplane, in Indonesia, November 2, 2018, in this still image taken from video obtained from social media.
Passengers on Sunday's flight reported terrifying descents and in both cases the different cockpit crews requested to return to their departure airport shortly after takeoff.
"This afternoon, investigators from the Australian Transport Safety Bureau will arrive to help download the black box data", he said. The plane crashed 13 minutes into its journey on Monday, killing 189 people that were on board.
Besides Lion Air, Garuda Indonesia and Batik Air were also upgraded to the same tier.
The shattering of the black box is unusual according to experts from US National Transportation Safety Board, since the devices are "built to withstand high-impact crashes". The US lifted a decade-long ban in 2016.
