Although Kaikohe has become established as the service centre of the Far North, it failed to generate much rail traffic in the early years of the line. During the first ten months of existence, just 1,500 tons of inbound freight was carried, with roughly half that carried outbound; the decline continued to the point that in 1918 Kaikohe lost its stationmaster. Minimal services were offered, and although losses increased up to 1930, fortunes had somewhat improved by 1940, and by 1950 there was sufficient traffic to justify six trains each way a week. Two carried solely freight, while four were mixed trains, also carrying passengers. Full complements of staff were employed at Kaikohe and Ōkaihau, where a locomotive depot was located.
