Local transport in New Zealand is quite convenient. You can get around by road via buses, cars and campervans. Other options are by rail, by boat and even by plane.
People say that taking a domestic flight within the country becomes cheaper than renting a car or travelling by train! Air New Zealand has a vast network of cities and is the most trusted carrier. Other domestic carriers include Virgin Australia, Webjet New Zealand, Jetstar and Canterbury Aviation for charter flights.
Commuter rail services operate at Wellington and Auckland. Intercity railway services are also offered and managed by KiwiRail Scenic Journeys. The TranzAlpine takes you from Christchurch to Greymouth and back. The Northern Explorer travels between Auckland and Wellington and runs thrice in a week.
Buses are cheaper than other forms of transport here. However, the service is not quite frequent, and connections to major towns exist only once a day. Some of the best bus services are Atomic Shuttles, InterCity buses and Flying Kiwi Adventures, which takes you on a bus tour. Two-wheelers and four-wheelers are also common in this country and are an option used by many. You can rent a car or share a ride with somebody, i.e., carpooling.
You can travel between Wellington and Picton and these boat services are available daily. Bluebridge and Interislander are the ferry companies here. Auckland and Wellington have harbour ferries that commuters can access. Charter boats are also available on request.
