He was jointly charged with a 21-year-old male and a 24-year-old man was also arrested in relation to the aggravated robbery.
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.
During Armed Offenders Squad raids in the Maraenui-Marewa area following the attack, police recovered a stun gun and pistol in the Pandora area believed to have been used in the aggravated robbery.
Police have a warrant for Haywood's arrest and are appealing for information about his whereabouts.
