Constraints on extra neutral gauge bosons are obtained from e+e-→ f f at NLC energies. Model independent limits on the Z'f f couplings and lower limits on the Z' mass are discussed. Typical GUTs with MZ' up to (3 -- 6) √(s) can be excluded. A distinction between different GUT scenarios is possible if MZ'≤ 3√(s). Radiative corrections give only small changes to the Z' exclusion limits provided that appropriate cuts are applied. %The inclusion of systematic errors leads to slightly worse results for %MZ'lim.
