We demonstrate that, at a 500 GeV e+e- collider, inclusion of the ZZ-fusion process for production of a light standard-model-like Higgs boson can substantially increase the precision with which the ZZh coupling can be determined (using the model-independent recoil mass technique) as compared to employing only Zh associated production.
