Effects of four-Fermi-type new interactions are studied in top-quark pair production and their subsequent decays at future $e^+e^-$ colliders. Secondary-lepton-energy distributions are calculated for arbitrary longitudinal beam polarizations. An optimal-observables procedure is applied for the determination of new parameters.
