In this paper, we study the quasi-conformal curvature tensor C and projective curvature tensor P on a (k, µ)'-almost Kenmotsu manifold M^2n+1 of dimension
greater than 3. We obtain that if M 2n+1 is non-Kenmotsu and satisfies R · C = 0 or
P · P = 0, then it is locally isometric to the Riemannian product H^(n+1)(-4) × R^n.
