Earlier, Turkey's deputy prime minister Numan Kurtulmus said authorities were close to identifying the gunman after obtaining his fingerprints and a description of his appearance.
Newspaper reports said the attacker was thought to be from a central Asian nation.
The Islamic State (IS) group has claimed responsibility for the attack, describing the gunman as a "heroic soldier of the caliphate who attacked the most famous nightclub where Christians were celebrating their pagan feast".
It said the man opened fire from an automatic rifle and detonated hand grenades in "revenge for God's religion and in response to the orders" of IS leader Abu Bakr al-Baghdadi.
