  For Gauss-Bonnet gravity and in the context of holography we show how the
thermal DC conductivity can be obtained by solving a generalised system of
Stokes equations for an auxiliary fluid on a curved black hole horizon. For
more general higher derivative theories of gravity coupled to gauge-fields, we
also analyse the linearised thermal and electric currents that are produced by
DC thermal and electric sources. We show how suitably defined DC transport
current fluxes of the dual field theory are given by current fluxes defined at
the black horizon.
