Let A and B be unital finite separable simple amenable C*-algebras which satisfy the UCT, and B is Z-stable. We show that two unital homomorphisms from A to B are approximately unitarily equivalent if and only if they induce the same element in KL(A, B), the same affine map on tracial states and the same Hausdorffified algebraic K_1 group homomorphism. A complete description of the range of invariant for unital homomorphisms is also given.
