In the present work, a family of Calabi-Yau manifolds with a local Hamiltonian Killing vector is described in terms of a non linear equation whose solutions determine the local form of the geometries. The main assumptions are that the complex (3, 0)-form is of the form e ik Ψ, where Ψ is preserved by the Killing vector, and that the space of the orbits of the Killing vector is, for fixed value of the momentum map coordinate, a complex 4-manifold, in such a way that the complex structure of the 4-manifold is part of the complex structure of the complex 3-fold. The family considered here include the ones considered in [26]-[28] as a particular case. We also present an explicit example with holonomy exactly SU(3) by use of the linearization introduced in [26], which was considered in the context of D6 branes wrapping a complex 1-cycle in a hyperkahler 2-fold.
