  We show that the discrete duals of the free orthogonal quantum groups have
the Haagerup property and the completely contractive approximation property.
Analogous results hold for the free unitary quantum groups and the quantum
automorphism groups of finite-dimensional C*-algebras. The proof relies on the
monoidal equivalence between free orthogonal quantum groups and SUq(2) quantum
groups, on the construction of a sufficient supply of bounded central
functionals for SUq(2) quantum groups, and on the free product techniques of
Ricard and Xu. Our results generalize previous work in the Kac setting due to
Brannan on the Haagerup property, and due to the second author on the CCAP.
