The charged Higgs boson decays H^±→ W^± A1 and H^±→ W^± hi are studied in the framework of the next-to Minimal Supersymmetric Standard Model (NMSSM). It is found that the decay rate for H^±→ W^± A1 can dominate both below and above the top-bottom threshold. We suggest that p p→ H^± A1 is a promising discovery channel for a light charged Higgs boson in the NMSSM with small or moderate tanβand dominant decay mode H^± → W^± A1 which leads to W^± A1 A1. This W^± A1 A1 signature can also arise from the Higgsstrahlung process pp→ W^± h1 followed by the decay h1→ A1 A1. It is shown that there exist regions of parameter space where these processes can have comparable cross sections and we suggest that their respective signals can be distinguished at the LHC by using appropriate reconstruction methods.
