We study CP sensitive observables in neutralino production e+e- ->neutralino_i neutralino_j and the subsequent two-body decays of the neutralinoneutralino_i -> neutralino_n Z and of the Z boson Z -> l \bar l (q \bar q). Weidentify the CP odd elements of the Z boson density matrix and propose CPsensitive triple-product asymmetries. We calculate these observables and thecross sections in the Minimal Supersymmetric Standard Model with complexparameters \mu and M_1 for an e+e- linear collider with \sqrt{s}=800 GeV andlongitudinally polarized beams. We show that the asymmetries can reach 3% for Z-> l \bar l and 18% for Z -> q \bar q and discuss the feasibility of measuringthese asymmetries.Comment: 21 pages, 8 figures, comments and references added; version to appear  in Eur. Phys. J.
