The decay process $H^\pm \to W^\pm Z^0$ is analyzed at one-loop level and possible enhancement of the decay width is explored. We find that a novel enhancement can be realized by the Higgs non-decoupling effects with large mass difference between charged and CP-odd Higgs bosons. The branching ratio of the process can be a few % $\sim$ 10%. Therefore the decay mode may be detectable at LHC or future $e^+e^-$ linear colliders (LC's).Sprocl-tex, 5 pages including 3 figures.
