This paper reports on the deviations from standard model predictions for the pair production of Z{sup 0} at e{sup +}e{sup {minus}} colliders with the inclusion of mixing between ordinary and exotic leptons evaluated for the differential cross section and the longitudinal polarization asymmetry at LEP II (square root of s = 190 GeV) and at possible the next linear collider (square root of s = 600 GeV) energies. For heavy exotic leptons (m{sub E} {approx} 250 GeV) the deviations have distinctive features that could allow the possibility of distinguishing between mirror, vector-doublet and vector-singlet type of exotic lepton mixings.
