Within the QCD factorization framework, we investigatethe branching fractions and the direct CP asymmetries of decays B→K0*1430ρω and B→K0*1430ϕ under twodifferent scenarios in the standard model and the familynonuniversal Z′ model. We find that the annihilation termsplay crucial roles in these decays and lead to the majoruncertainties. For decays B-→K0*-1430ρ0ω,the new Z′ boson could change the branching fractionsremarkably. However, for other decays, its contribution might beclouded by large uncertainties from annihilations. Unfortunately,neither the standard model nor the Z′ model can reproduceall experimental data simultaneously under one certain scenario. Wealso noted that the direct CP asymmetries of B-→K0*-1430ρ0ω could be used to identify the K0*1430 meson and search for the contribution of new Z′ boson
