We report new spectroscopic classifications by OzDES of supernovae discovered by the Dark Energy Survey (ATEL #4668). The spectra (370-885nm) were obtained with the AAOmega Spectrograph (Saunders et al. 2004, SPIE, 5492, 389) and the 2dF fibre positioner at the Anglo-Australian Telescope (AAT). Object classification was performed using SNID (Blondin & Tonry, 2007, ApJ, 666, 1024) and superfit (Howell and Wang, 2002, BAAS, 34, 1256), the details of which are reported in the table below. Host galaxy line identification and redshifts were obtained using MARZ (Hinton et al. 2016, A&C, 15, 16).
