The effects of new neutral $Z^\prime$ boson in$B_{s}\to\phi\ell^{+}\ell^{-}$, when $\phi$ is longitudinal or transversepolarized, are studied. In addition, the implications of $Z^{\prime}$ boson onthe unpolarized and polarized $CP$ violation asymmetries, with reference tolepton, are also presented. It is observed that the branching ratio withpolarized $\phi$ are quite sensitive to the $Z^{\prime}$ contributions whichare coming through the modification of Wilson coefficients $C^{eff}_{9}$ and$C_{10}$. Moreover, the off-diagonal elements of the chiral $Z^{\prime}$couplings contain new weak phase $\phi_{sb}$ that provide a new source of $CP$violation. Keeping in view that in the FCNC transitions the $CP$ violationasymmetries are highly suppressed in the SM, we have studied the unpolarizedand polarized $CP$ violation asymmetries in $B_{s}\to\phi\ell^{+}\ell^{-}$decays. Our results indicate that these $CP$ violation asymmetries areremarkably significant and can attribute the any new physics coming through the$Z^{\prime}$ boson. It is hoped that the accurate measurements of theseasymmetries will not only help us to establish NP but will also give a chanceto determine the precise values of the coupling parameters of the $Z^{\prime}$boson.
