We study CP-sensitive observables in the neutralino production and the subsequent two-body decays of the neutralino 
and of the Z boson 
. We identify the CP-odd elements of the Z boson density matrix and propose CP-sensitive triple-product asymmetries. We calculate these observables and the cross sections in the minimal supersymmetric standard model with complex parameters μ and M
1 for an e
+
e
- linear collider with 
GeV and longitudinally polarized beams. We show that the asymmetries can reach 
for 
and 
for 
and discuss the feasibility of measuring these asymmetries.
