Onerahi Branch - History

History

In the early 1880s, a wharf near the city of Whangarei had been established in the upper reaches of Whangarei Harbour. Roughly 20 years later the maintenance bill was rising and the wharf's inadequacies were being revealed as it was too shallow for some vessels to access. The deep-water wharves in nearby Onerahi were considerably more desirable, and in 1899 approval was granted to extend the railway from Whangarei to Onerahi. It took until July 1901 for construction to get underway, and in May 1902 a contract was let to build a bridge across Whangarei Harbour. It was 323 metres long with a central lifting span, and completed in 1904. It was not long before the bridge was nicknamed the Gull Roost, for obvious reasons.

Some work continued for two years after the bridge was finished, but construction ground to a halt in 1906 and no more work was done for four years. It recommenced during 1910 and the line was finished the next year. It came into the possession of the Railways Department on 2 October 1911. At this time, it was the southern end of the isolated Whangarei railway network, which extended northwards to Okaihau and Opua, and construction of the North Auckland Line that would link the isolated section to Auckland and the national rail network was underway.
