  We examine the effects of the extended gauge sector of the Littlest Higgs
model in high energy e+e- collisions. We find that the search reach in e+e- ->
f fbar at a 500 GeV center-of-mass energy International Linear Collider covers
essentially the entire parameter region where the Littlest Higgs model is
relevant to the gauge hierarchy problem. In addition, we show that this channel
provides an accurate determination of the fundamental model parameters, to the
precision of a few percent, provided that the LHC measures the mass of the
heavy neutral gauge field. Additionally, we show that the couplings of the
extra gauge bosons to the light Higgs can be observed from the process e+e- ->
Z higgs for a significant region of the parameter space. This allows for
confirmation of the structure of the cancelation of the Higgs mass quadratic
divergence and would verify the little Higgs mechanism.
