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 50-nautical-mile (93 km; 58 mi) route, taking about three hours to complete the crossing. 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.
