  CP violation in the lepton sector, and other aspects of neutrino physics, are
studied within a high scale supersymmetry model. In addition to the sneutrino
vacuum expectation values (VEVs), the heavy vector-like triplet also
contributes to neutrino masses. Phases of the VEVs of relevant fields, complex
couplings and Zino mass are considered. The approximate degeneracy of neutrino
masses $m_{\nu_1}$ and $m_{\nu_2}$ can be naturally understood. The neutrino
masses are then normal ordered, $\sim$ 0.020 eV, 0.022 eV, and 0.054 eV. Large
CP violation in neutrino oscillations is favored. The effective Majorana mass
of the electron neutrino is about 0.02 eV.
