We study $Z^{\prime}$ phenomenology at hadron colliders in an $U(1)^{\prime}$ extended MSSM. We choose a $U(1)^{\prime}$ model with a secluded sector, where the tension between the electroweak scale and developing a large enough mass for $Z^{\prime}$ is resolved by incorporating three additional singlet fields into the model. We perform a detailed analysis of the production, followed by decays, including into supersymmetric particles, of a $Z^{\prime}$ boson with particular emphasis on its possible discovery. We select three different scenarios consistent with the latest available experimental data and relic density constraints, and concentrate on final signals involving $2\ell+\not\!\!E_{T}$,$4\ell+\not\!\!E_{T}$ and $6\ell+\not\!\!E_{T}$. Including the SM background from processes with two, three or four vector bosons, we show the likelihood of observing a $Z^\prime$ boson is not promising for the HL-LHC at 14 TeV, but optimistic for 27 and 100 TeV.
