Despite being frustrated in the first half, Granit Xhaka opened the scoring for the Gunners with an excellent long-range free-kick after the break, before Ozil followed up Alexandre Lacazette’s blocked effort to double the advantage.
Ciaran Clark responded in stoppage time for the hosts, however Newcastle remain 18th in the table with one win in their past 10 league games.
Ozil – making his 200th appearance for the club – ensured Arsenal won consecutive away league games for the first time since May 2017.
“His quality helps the team. It is important he scored. I want not only for him to assist, we need him to go in the box and score like today,” said Emery – who had challenged the midfielder to “do more” before the game.
“I see the players are the same, each has quality. I will work with every player and continue our process to create the team as we want.”
Meanwhile, Rafael Benitez’s side remain on one point, equalling their worst return after five Premier League games – although they had much the better of the first-half chances as they pressed an Arsenal defence determined to build from the back.
The early pressure forced errors, as keeper Petr Cech passed the ball out for a corner and defender Shkodran Mustafi’s stumble was indicative of an Arsenal back-line still trying to get comfortable with a new style of play under Emery.
However, Arsenal returned the stronger side after the interval and scored twice in 10 second half minutes to secure the points – despite a late Newcastle rally.
