Ther rare B-s -> gamma nu(nu) over bar decay with polarized photon is studied in the framework of a family nonuniversal Z' model. Thebranching ratio and photon polarization asymmetry to the model parameters are calculated and compared with the Standard Model. Deviations from the Standard Model will indicate the presence of new physics.
