Its focus was initially – and remains to this day – on supporting contemporary art and culture in the region, especially through the acquisition of artworks which are made available to the Sprengel Museum Hannover on permanent loan.

This also includes the goal of contributing to the creation of intragenerational justice and leaving behind a liveable world for future generations.

Since 2023 the Hannover Re Foundation has additionally assumed responsibility for the "Masterclass Students" exhibition series, which was launched back in 2014 in cooperation with Braunschweig University of Art.
