  In this paper, we explore the collider phenomenology of the charged Higgs
boson in the context of a generic Beyond Standard Model scenario with extended
gauge and scalar sectors. In such scenarios, the charged Higgs boson can decay
via the $W^{'}Z/ WZ^{'}$ channels. We formulate a search strategy for the
$H^{\pm}$ in the channel $\sigma(g b \rightarrow H^{\pm}t)\mathcal{BR}(H^{\pm}
\rightarrow W' Z)$ considering the interesting cascade decay chain $H^{\pm}
\rightarrow W^{'} Z \rightarrow W^{\pm} Z Z$. We find that the charged Higgs
can be discovered in final states with multiple hard leptons and/ or b-quarks
which future LHC experiments with sufficiently large luminosity ($\mathcal{L} =
1000 fb^{-1}$ and above) can probe.
