Decay of SM-like Higgs boson $h\rightarrow Z\gamma$ in the G221 model is investigated. We show that new particles predicted by this model may give significant effects to this decay channel of the SM-like Higgs boson. The analytical results are expressed in terms of well-known Passarino-Veltman functions which their numerical evaluations can be generated using LoopTools. Our results are also well stable with different values of $s_h, m_h, t_b$ and $m_V$. From numerical investigation, some details and properties of this decay are presented. They may be useful for comparing with the experimental results that could be detected in the future.
