As the fundamental SU(2) supersymmetric parameters can be determined in the chargino sector, and the remaining fundamental parameters of the minimal supersymmetric extensions of the standard model can be analyzed in the neutralino sector, the two sectors can be correlated via these parameters. We have shown that for the CP conserving case, the masses of all the neutralinos can be determined in terms of the chargino masses, and $\tan\beta$. In this case the neutralino masses are quite insensitive to the variations of $\tan\beta$; they change by about $%15$ when $\tan\beta$ varies in the range from 5 to 50. In the CP violating case, the neutralino masses are found to be quite sensitive to the variations of the CP violating phase. For the heavier neutralinos the dependence of the masses to the CP violating phase show complementary behaviour at CP violating points.
