Yes, there is a very well-established car ferry service across the Cook Strait between the North Island (Wellington) and the South Island (Picton). Two primary companies operate this route: Interislander and Bluebridge. As of 2026, these ferries run multiple times daily, with the journey taking approximately 3.5 hours. These are not just transport vessels but "mini-cruise ships" featuring cafes, bars, cinemas, and observation decks to take in the spectacular views of the Marlborough Sounds. Traveling with a vehicle is straightforward; you simply drive onto the ship’s vehicle deck and secure your car before heading up to the passenger lounges. Prices for a standard car usually start around NZ$230 to $260 for a one-way trip, plus the per-passenger fare. It is highly recommended to book several weeks in advance, especially during the peak summer months (December to March), as these sailings often sell out. The crossing is considered one of the most scenic in the world, often featuring sightings of dolphins, seals, and whales. If you are prone to seasickness, it is wise to check the weather forecast, as the Cook Strait can occasionally be quite rough, leading to delays or cancellations.
