We study the Z(4430)(+/-) meson within a heavy hadron molecule interpretation where the Z is considered as a bound state of a vector D*(2010) and an axial-vector D-1(2420). We give predictions for the strong hidden-charm Z(4430)(+/-) -> pi(+/-) psi and pi(+/-) psi' decay widths and also study the radiative Z(+/-)(J(P) = 1(-)) -> pi(+/-) gamma decay properties in a phenomenological Lagrangian approach. Our findings are qualitatively in line with the experimental observation that the pi(+/-) psi' transition dominates over the pi(+/-) psi decay mode despite a smaller phase space. The width for the radiative mode pi(+/-) gamma is sizable, allowing possible detection in future experiments.
