Abstract
Model independent constraints on the mass of extra neutral gauge bosons and their couplings to charged leptons are given for LEP II and a 500 GeV e{sup +}e{sup -} collider. Analytical exclusion limits are derived in the Born approximation. The Z` limits obtained with radiative corrections are always worse than those calculated at the Born level. Polarized beams are only useful for degrees of polarization essentially larger than 50%. Known discovery limits on extra Z bosons predicted by popular Z` models are reproduced as special cases. The Z` constraints are compared to those predicted by four fermion contact interactions. (orig.)
