We present the combined NuSTATR and XMM-Newton 0.6-79 keV spectral analysisof a Seyfert 2 galaxy, NGC 1358, which we selected as a candidate Compton thick(CT-) active galactic nucleus (AGN) on the basis of previous Swift/BAT andChandra studies. According to our analysis, NGC 1358 is confirmed to be aCT-AGN using physical motivated models, at >3 $\sigma$ confidence level. Ourbest-fit shows that the column density along the 'line-of-sight' of theobscuring material surrounding the accreting super-massive black hole is N$\rm_H$ = [1.96--2.80] $\times$ 10$^{24}$ cm$^{-2}$. The high-quality data fromNuSTAR gives the best constraints on the spectral shape above $\sim$10 keV todate on NGC 1358. Moreover, by combining NuSTAR and XMM-Newton data, we findthat the obscuring torus has a low covering factor ($f_c$ <0.17), and theobscuring material is distributed in clumps, rather than uniformly. We alsoderive an estimate of NGC 1358's Eddington ratio, finding it to be$\lambda_{\rm Edd}$ $\sim$$4.7_{-0.3}^{+0.3}$ $\times$ 10$^{-2}$, which is inacceptable agreement with previous measurements. Finally, we find no evidenceof short-term variability, over a $\sim$100 ks time-span, in terms of both'line-of-sight' column density and flux.
