Abstract: It is of interest to study supergravity solutions preserving a nonminimal fraction of supersymmetries. A necessary condition for supersymmetry to be preserved is that the space‐time admits a Killing spinor and hence a null or time‐like Killing vector field. Any space‐time admitting a covariantly constant null vector (CCNV) field belongs to the Kundt class of metrics and more importantly admits a null Killing vector field. We investigate the existence of additional non‐space‐like isometries in the class of higher‐dimensional CCNV Kundt metrics in order to produce potential solutions that preserve some supersymmetries.
