We examine the influence of gauge kinetic mixing on the couplings of a TeVscale $Z'$ in both $E_6$ and SO(10) models. The strength of such mixing, whicharises due to the existence of incomplete matter representations at low scale,can be described by a single parameter, $\delta$. The value of this parametercan significantly influence the ability of both hadron and lepton colliders todetect a $Z'$ using conventional search techniques. In addition, $\delta \neq0$ also adds to the complexities involved in separating $E_6$ $Z'$ models fromthose arising from alternative scenarios. Employing a reasonable set ofassumptions we have determined the allowed range for this parameter within awide class of models via an RGE analysis. In particular, given the requirementsof Standard Model gauge coupling unification, anomaly freedom andperturbativity up to the GUT scale, we demonstrate that the necessary conditionfor exact leptophobia in $\eta$ type $E_6$ models, $\delta=-1/3$, is impossibleto achieve in this scenario. Furthermore we show that the allowed range for$\delta$ is rather restricted for arbitrary values of the mixing between the$U(1)_\chi$ and $U(1)_\psi$ type couplings. The SO(10) $Z'$ model $\chi$ isdiscussed as a separate case since it requires special attention.Comment: several typos correcte
