The NZR DF class of 1979 is a class of 30 Co-Co diesel-electric locomotives built by General Motors Diesel of Canada between 1979 and 1981. Between 1992 and 1997, all the locomotives were rebuilt as the DFT class, a turbocharged version of the DF.

The class should not be confused with the English Electric DF class of 1954; as all of the old DFs had been retired by mid-1975, the 'DF' classification was free to be re-used.
