Steam engines were still the dominant source of power for industry in New Zealand in 1905, and this diesel engine and its companion were the first in the country, indeed the first in the Southern Hemisphere. Their purchase, coming soon after the perfection of the compression ignition diesel system and the commercialisation of the technology in 1897, represents a relatively early adoption of new technology and indicates significant faith in the improved efficiency proclaimed for diesel engines.
