Motivated by the generation of action principles from off-shell dualisation, we present a general class of free, topological theories in three dimensions that exhibit higher-spin gauge invariance. In the spin-2 case, we recover the triplet system already known before. The higher-spin systems that we obtain, on the other hand, seem to be new. We show that the flat limit of our action around (A)dS_3 background gives rise to a one-parameter family of inequivalent actions in Minkowski space.
