We report the feasibility study of observing associated production of Higgs and Z^0 bosons with H -> bb-bar and Z^0 -> nu nu-bar, l^+l^- at sqrt s = 2 TeV high luminosity Tevatron (TeV33). The signature of such decay is a resonance of two b tagged jets, plus either large missing E_t (missing E_T > 35 GeV) or dilepton pair mass near the Z^0 mass. The signal and backgrounds are estimated using the CDF II detector configuration and the numbers are cross checked against the existing CDF Run I missing E_T data. It may be possible to detect a Standard Model Higgs boson mass up to 120 GeV with 30 fb^-1 of integrated luminosity by combining a result with W^+/- H -> l^+/- nu b b-bar channel.
