  We present medium-resolution (R $\sim$ 4000) YJ, H \& K band spectroscopy of
candidate young stellar objects (YSOs) in NGC~346, the most active
star-formation region in the metal-poor (Z = 1/5 Z$_{\sun}$) Small Magellanic
Cloud. The spectra were obtained with the KMOS (K-Band Multi Object
Spectrograph) integral field instrument on the Very Large Telescope. From our
initial sample of 18 candidate high-mass YSOs previously identified from mid-IR
photometry and radiative transfer model fits to their spectral energy
distributions, approximately half were resolved into multiple components by our
integral-field data. In total, we detect 30 continuum sources and extract
reliable spectra for 12 of these objects. The spectra show various features
including hydrogen recombination lines, and lines from H$_2$, He~{\sc i} and
[Fe~{\sc ii}], which are indicative of accretion, discs and outflowing material
in massive YSOs. We spectroscopically confirm the youthful nature of nine YSO
candidates and identify two others as OB stars. All of the confirmed YSOs have
Br$\gamma$ in emission, but no emission is seen from the CO bandhead, despite
other disc tracers present in the spectra. He\,{\sc i}~1.083 $\mu$m emission is
also detected at appreciably higher rates than for the Galaxy.
