Interislander Where the journey becomes a destination. Interislander travels between the North and South Islands of New Zealand and is one of the most spectacular cruises in the world. With 92 km of breathtaking views, the three-hour journey between Wellington and Picton really is one of New Zealand’s most iconic tourism activities. Interislander operates three ships, the Kaitaki, Arahura and Aratere, for you and your vehicle. We have up to 11 sailings a day, so you’ll always have a wide choice of travel times. Once you’re on your Interislander journey, you can take a stroll on the decks, enjoy a meal, a drink or even catch the latest movie releases. Or you could just choose to relax and take in the breathtaking view.
