We study how the supersymmetry algebra extension of N=2 supergravity with central charges describes the NUT charge in a duality-covariant way. The stationary BPS states of N=2 supergravity can be embedded in the flat space solution of the timelike reduced theory. Upon reduction, the Killing superalgebra extension and the global superalgebra of charges are described covariantly under the coset structure of the three-dimensional theory. The integral of the Nester-Witten form given by Gibbons and Hull for N=2 has a covariant generalization that includes the NUT charge.
