Abstract: Let $ G$ be a finite abelian group. We will consider a skew product extension of a product of two Cantor minimal $ \mathbb{Z}$-systems associated with a $ G$-valued cocycle. When $ G$ is non-cyclic and the cocycle is non-degenerate, it will be shown that the skew product system has torsion in its coinvariants.
