We study vacuum stability of supersymmetric extended Higgs sectors with a discrete Z2 symmetry. These models may be able to explain dark matter, neutrino masses, baryon asymmetry of the Universe and hierarchy problem simultaneously at the TeV scale. This Z2 symmetry could be broken spontaneously. We examine the stability of the Z2 symmetric vacuum at the tree level in several models with such extended Higgs sectors.
