The relativistic multiconfiguration Dirac-Hartree-Fock and the nonrelativistic multiconfiguration Hartree-Fock methods have been employed to calculate the magnetic dipole and electric quadrupole hyperfine structure constants of zinc. The calculated electric field gradients for the $4s4p{}^{3}P_1^o$ and $4s4p{}^{3}P_2^o$ states, together with experimental values of the electric quadrupole hyperfine structure constants, made it possible to extract a nuclear electric quadrupole moment $Q\left({}^{67}\mathrm{Zn}\right)=0.122\left(10\right)$ b. The error bar was evaluated in a quasistatistical approach—the calculations were carried out with 11 different methods, and then the error bar was estimated from the differences between the results obtained with those methods.
