The clip - directed by Spanish collective Canada - is set in a futuristic arena, where two teams enter combat on motorcycles similar to the 1975 film Rollerball.
'New Lands' marks the fourth single from Justice's latest album Audio, Video, Disco, which was released in October last year.
The single's EP is out now and features remixes from Sebastian and Falcon, as well as a live recording of the track.
The band are due to headline Berlin's Melt Festival on July 13 - 15 alongside Bloc Party and Two Door Cinema Club.
