In this paper, we used the multiconfiguration Dirac-Fock method to compute with high precision the influence of the hyperfine interaction on the $[Ar]3d^{10} 4s4p\ ^3P_0$ level lifetime in Zn-like ions for stable and some quasi-stable isotopes of nonzero nuclear spin between $Z=30$ and $Z=92$. The influence of this interaction on the $[Ar]3d^{10} 4s4p\ ^3P_1 - [Ar]3d^{10} 4s4p\ ^3P_0$ separation energy is also calculated for the same ions.
