Interislander is a road and rail ferry service across New Zealand's Cook Strait, between Wellington in the North Island and Picton in the South Island. It is owned and operated by state-owned rail operator KiwiRail. Three roll-on roll-off (RORO) vessels operate the route, taking about three hours to complete the crossing. The inter-island rail ferry service began in August 1962 by the New Zealand Railways Department (NZR). The service primarily provided a RORO rail link between its North and South Island networks, allowing NZR to compete directly with coastal shipping companies for inter-island freight. It also provided the first RORO road link between the two islands, which saw the Wellington to Picton ferries compete with, and then completely replace, the Union Company's Wellington–Lyttelton ferry service. Today, the Interislander service is still well patronised despite competition on the Wellington–Picton sea route with Bluebridge and from airlines, carrying around one million passengers and 230,000 vehicles per year on 5,500 sailings. In 2017, Interislander became part of The Great Journeys of New Zealand, a new tourism brand created by KiwiRail to unite its four scenic passenger services: Interislander, Northern Explorer, Coastal Pacific and the TranzAlpine. History Introduction Before 1962, the North Island and South Island rail networks were not connected, and the New Zealand Railways Department (NZR) struggled to compete with ships for inter-island transport. In the days before containerisation, rail freight between the islands had to be railed in a wagon to Wellington, unloaded and transferred onto a ship to Picton or Lyttelton, then loaded into another wagon before being railed the rest of the way. The Union Steam Ship Company (USSC) ran an overnight ferry between Lyttelton and Wellington using steamers. NZR also contracted SAFE Air to run its Rail Air airfreight service for freight between the islands, from Paraparaumu to Blenheim, but this was limited to aircraft payloads. The decision to start a rail ferry was made in 1958 by the Cook Strait Transport Enquiry Committee. The enquiry was set up following Union Steam Ship's decision to withdraw the unprofitable Tamahine, built in 1925. NZR was officially reluctant to compete with USSC for inter-island traffic, but supplied the New Zealand Railway Officers' Institute with information to put to the enquiry. The Cook Strait Inter-Island Rail and Road Service (as it was known) started on 11 August 1962 with the roll-on roll-off ferry . The service dramatically increased efficiency, since freight
