We have investigated $B \to (K,K^*)(l\bar l,\nu\bar\nu)$ decay channels andpredicted some form factor dependent observables (e.g. branching ratio,forward-backward asymmetry and lepton polarization asymmetry) considering newphysics contribution from non-universal $Z'$ model. We have found that there isappreciable difference between the standard model and $Z'$ model predictions.Recently, the lepton flavour non-universality parameters $R_K$ and $R_{K^*}$have been measured by the LHCb collaboration and are found to be different fromtheir standard model predictions. These deviations provide the hint of flavornon-universality in lepton sector and motivate our research to look for newphysics beyond the standard model. The $R_K$ and $R_{K^*}$ anomalies may be dueto new physics in either electron or muon sector or both. In our work, we haveshown that the experimental results of $R_K$ and $R_{K^*}$ could be achieved innon-universal $Z'$ model considering the new physics couplings to muon sectoronly.
