Adam Hlousek gave the visitors a surprise first-half lead before Emar Elabdellaoui levelled to give Braunschweig their first point of the season.
Despite having only found the net once so far this term, home side Braunschweig made a decent start and nearly had an early lead when Karim Bellarabi was denied one-on-one by goalkeeper Raphael Schafer.
Nurnberg took the lead after 28 minutes when Hlousek managed to get on the end of Timothy Chandler’s low cross at the far post to tap home.
The goal was harsh on Braunschweig, who nearly responded in the perfect manner when Deniz Dogan’s free-kick forced a good save from Schafer.
In the day’s only other game, Hoffenheim bounced back from their 6-2 mauling at Stuttgart last week to earn a 2-1 win at home to Borussia Monchengladbach.
