Ataria appeared in the dock yesterday with bruising to his face and a bandage around one of his fingers.
Court documents allege Ataria and his co-accused entered the Bluewater Hotel with intent to commit an imprisonable offence in the building, using a pistol as a weapon.
They are also charged with causing grievous bodily harm with intent after the victim received head injuries and a potentially fractured arm.
Both charges carry a maximum penalty of 14 years' imprisonment.
Ataria was represented by duty lawyer Philip Jensen, who did not make any bail application. Ataria was remanded in custody until February 26.
Bluewater Hotel owner Rodney Green said that about 4pm yesterday police relinquished control of the hotel room where the incident took place.
"Lots of people have been inquiring but we really don't know anything about what happened," he said.
Members of the Armed Offenders Squad searched two houses in the Maraenui-Marewa area yesterday, looking for a "number of people" who they believed were involved in the incident. While no arrests were made during the searches, an electric stun device and a pistol were found in the Pandora area that police believe could be related to the assault.
A police spokesperson thanked members of the public who heard the assault on Thursday morning and contacted the police. The spokesperson said they provided vital information and helped in finding the arrested persons.
