The associated production of a Z′ and a final hard photon in high energy electron-positron colliders is studied. It is shown that the hard photon spectrum contains useful information on the Z′ properties. This remark suggests that, if a new neutral gauge boson exists for MZ′<s, it will not be necessary to make a new energy run at the Z′ mass in order to get most of its properties.
