The duo debuted 'Diver' as the latest track to be lifted from their forthcoming debut album, which is expected to be released later this year.
AlunaGeorge unveiled the new cut after finishing second on the BBC's Sound of 2013 list earlier today (January 3).
"There is a little bit more pressure now because people expect a certain level or certain feel to the music, but that pressure is a massive blessing," George Reid said of their placing on the annual list.
Aluna Francis added: "We take the music to its bare bones. We've got good beats that are either sexy or dancey and then songs on top."
The London pair were named the most blogged-about new music act of 2012, which led to them being shortlisted for the coveted Brits Critics' Choice award.
'Diver' follows AlunaGeorge's previous singles 'You Know You Like It' and 'Your Drums, Your Love', which were both released in 2012.
