Remarks:     These locomotives were the first tender engines for service with the NZR. They were intended for heavy goods traffic on the Canterbury Plains, although they went on to express work between Auckland and Rotorua, as well as duties in Napier. Four were converted into Wa Class 2-6-2 tank locos, and several others were given tender cabs to make them suitable for shunting duties.
