We study the process e(+)e(-) -> nu(nu) over bar gamma to search for its sensitivity to the extra gauge bosons Z(2), Z(3) and W-2(+/-), which are suggested by the little Higgs models. We find that the ILC with root s= 0.5 TeV and CLIC with root s = 3 TeV cover different regions of the LHM parameters. We show that this channel can provide a determination of the parameters, complementary to measurements of the extra gauge bosons obtainable at the upcoming LHC experiments.
