Flux motion in anisotropic type-II superconductors near H{sub c2} is studied in the framework of the time-dependent Ginzburg-Landau (TDGL) theory for the case that the average flux density B is oriented in an arbitrary direction relative to principal axes of the sample. The linearized TDGL equation for a uniformly translating order parameter is solved and expressions for all elements of the flux-flow resistivity tensor {rho}{sub ij} (including the off-diagonal Hall elements) are obtained. The diagonal elements {rho}{sub ii} show the angular scaling property that {rho}{sub ii}(B) = {rho}{sub ii}(B/H{sub c2}({theta}, {phi})), whereas the Hall elements {rho}{sub ij} (i {ne} j) have additional angular dependences that are not contained in H{sub c2}. For the case that the normal state Hall elements {rho}{sub ij}{sup (n)} {proportional_to}B{sub k} with i {ne} j {ne} k, the ratios {rho}{sub ij}/{rho}{sub ij}{sup (n)} are functions of B/H{sub c2} ({theta},{phi}) only.
