The Gunners manager confirmed the trio will be back in contention at the Emirates on Saturday as they look to cement top spot in the Premier League with a win over the Canaries
Ozil limped out of Germany's World Cup qualifying victory over Sweden in midweek, while Sagna and Cazorla have both been unavailable since before the international break.
Goal explained the Spain star had returned to full training during the Premier League break, and Wenger now appears to have a clean bill of health in his squad.
"Ozil, Sagna and Cazorla are all fit," Wenger told reporters. "Everybody else looks fit and ready."
Wenger was previously undecided as to whether he would start Sagna or Cazorla on Saturday's match, with a settled team riding high at the top of the league.
"Cazorla is available in training, but he is not match-fit. It is just about competitiveness with him," he told Arsenal Player. "There is a possibility both are in the squad for Saturday. I have not decided whether they will start or not."
Wenger's comments also indicate England forward Theo Walcott is likely to play a part against Norwich at the Emirates Stadium on Saturday.
The Gunners endured a tough start to the campaign with a 3-1 defeat at home to Aston Villa raising questions over Arsene Wenger's long-term future at the club.
However, the dramatic deadline day capture of club-record signing Ozil has seen a reversal of fortunes, with the north Londoners top of the Premier League with 16 points from seven games, including an eight-match win streak in all competitions.
