We present fully differential next-to-leading order results for Higgs production in association with a Z boson in gluon fusion. Our two-loop virtual contributions are evaluated numerically using sector decomposition, including full top-quark mass effects, and supplemented at high pT by an analytic high-energy expansion to order mZ4, mH4, mt32. Using the expanded results we also present a study of the top-quark mass scheme uncertainty at large pT.
