An experimental study of the ${}^{62}$Zn nucleus has been performed by combining the data sets from four fusion-evaporation reaction experiments. Apart from the previously published data, the present results include ten new rotational band structures and two more superdeformed bands. The Gammasphere Ge-detector array in conjunction with the 4$\ensuremath{\pi}$ charged-particle detector array Microball allowed for the detection of $\ensuremath{\gamma}$ rays in coincidence with evaporated light particles. The deduced level scheme includes some 260 excited states, which are connected with more than 450 $\ensuremath{\gamma}$-ray transitions. Spins and parities of the excited states have been determined via directional correlations of $\ensuremath{\gamma}$ rays emitted from oriented states. The experimental characteristics of the rotational bands are analyzed and compared with results from cranked Nilsson-Strutinsky calculations. The present analysis, combined with available experimental results in the $A\ensuremath{\sim}60$ mass region, can be used to improve the current set of Nilsson parameters in the $\mathcal{N}=3$ and $\mathcal{N}=4$ oscillator shells.
