The variable star DZ Cru was thought to be a nova when it was discovered in eruption in 2003 August. This explanation was later challenged, however, when the first spectra of the object were reported. We present near-infrared spectroscopy of DZ Cru obtained at the New Technology Telescope on three occasions, starting ∼1.5 yr after outburst, with the aim of establishing the nature of the object. The spectra display Hi, Oi, [Ni] emission lines, together with Hei P Cygni lines superposed on a dust continuum. These observations suggest the `peculiar variable in Crux' is a classical nova.
