The NZR DH class is a type of diesel-electric shunting locomotive in New Zealand. The class consists of six heavy shunt U10B type loco built by General Electric in the US in 1978. The class are almost all used in the Auckland area for heavy shunting duties, including services to the Port of Auckland.

The class should not be confused with the English Electric DH class of 1956; as all of the old DHs had been reallocated DG in 1968, the classification was re-used.
