Hauger stayed with Stabæk in the First Division[5] and was one of the best players at the second tier when the club won promotion back to Tippeligaen in the 2005 season.

[10] Hauger made his debut for Hannover 96 on 6 August 2011, when he played the last 21 minutes as a substitute for Pinto in the opening match of the 2011–12 Bundesliga against TSG 1899 Hoffenheim.

This was Hauger's first call-up for the senior team,[7] and he made his debut for Norway when he replaced Magne Hoseth at half time in the 2–1 loss against Mexico.
