Interislander or Bluebridge? A side-by-side comparison of New Zealand's two Cook Strait ferries — prices, crossing time, ships, campervan rules and which to pick.

Both ferries link Wellington (North Island) and Picton (South Island) across Cook Strait. They cover the same water in a similar time — so the choice comes down to schedule, price, ship comfort and whether you’re bringing a vehicle.
The quick answer
If you want more daily sailings and slightly newer terminals, lean Interislander (the KiwiRail-operated service). If you’re chasing the lowest fare or a specific departure time, check Bluebridge first — it’s often a touch cheaper and its terminal sits right in central Wellington. Prices move with demand, so always compare both for your exact date.
| Interislander | Bluebridge | |
|---|---|---|
| Operator | KiwiRail | StraitNZ |
| Crossing time | ~3h 30m | ~3h 30m |
| Sailings/day | More frequent | Fewer, often overnight option |
| Wellington terminal | Aotea Quay (shuttle) | Central, near the CBD |
| Best for | Flexibility, frequency | Budget fares, central pick-up |
Taking a campervan or car across
Both lines carry vehicles, and this is where booking early matters most. Vehicle space — especially for campervans and motorhomes over 5.5 m — sells out fast in summer. You pay per vehicle length plus per passenger, so a large motorhome costs significantly more than a compact camper. If you’re on a relocation deal, confirm whether the crossing is included before you book.
Which crossing is smoother?
Cook Strait has a reputation as one of the world’s more unpredictable stretches of water. On a calm day it’s a gentle, scenic cruise; in a southerly it can be rough on either ferry. The ship matters more than the brand here — check which vessel is scheduled and pack motion-sickness tablets if you’re sensitive. The final hour, winding through the Marlborough Sounds into Picton, is worth staying on deck for.
FAQ
Is Interislander or Bluebridge cheaper?
Bluebridge is often marginally cheaper, but both use demand-based pricing. For any given date, compare both — a well-timed Interislander sailing can undercut Bluebridge and vice versa.
How early should I book the ferry with a campervan?
For summer (December–February), book vehicle space weeks ahead. Foot passengers have far more flexibility.
Can I bring my rental across the strait?
Almost always yes, but confirm with your rental company — a few one-way and relocation contracts restrict which island you can take the vehicle to.
