New interactions appearing at a scale $\Lambda$ larger than the weak interaction scale v can affect physical processes at energies below $\Lambda$ through non-renormalizable $SU(3)\times SU(2)\times U(1)_y$ invariant operators added to the standard model Lagrangian. In this article we investigate the effect of flavor conserving contact interactions on the total cross-section for the process $e^+e^-\to HZ$ at $\sqs =500$ Gev. We find that for $\Lambda\approx 2.5 $ Tev, which is consistent with LEP and SLD asymmetry measurements on Z peak as well as theoretical estimates, these operators can increase the total cross-section by a factor of 3 relative to the SM for intermediate mass higgs boson.
