To cross from New Zealand’s North Island to its South Island (or visa-versa) you need to get a ferry across the Cook Strait. This is one of the most beautiful ferry journeys anywhere on earth so think of it as a cruise not just transport!
There are two companies that run ferries on this route. Both sail between Wellington on the North Island & Picton on the South Island. Both have online booking facilities, cost roughly the same & take roughly the same time. So try both for prices:
To help you, our vans are classed as campervans. They are 4.9m long.
