Cook Strait ferry guide

Which Cook Strait ferry should I take: Interislander or Bluebridge?

Both cover the Wellington-Picton crossing in approximately 3h30. Interislander is the larger, more established operator with more sailings. Bluebridge tends to be slightly cheaper and has a loyal following. Book vehicles 4-6 weeks ahead in peak season. Foot passengers can usually book much closer to sailing.

Crossing Cook Strait: what to expect

Cook Strait is one of the most dramatic maritime passages in the world. Twenty-six kilometres at its narrowest point, with the Tasman Sea and Pacific Ocean meeting at a shallow continental shelf — it can be mirror-flat on a summer’s day or genuinely violent in winter swells. The crossing connects Wellington (at the southern tip of the North Island) with Picton (at the northern tip of the South Island’s Marlborough Sounds).

For anyone driving the length of New Zealand, this is not optional. There is no road bridge and no tunnel. You either take the ferry, fly over (Wellington to Christchurch or Nelson), or arrange separate vehicles on each island.

The good news: even in rough weather, the ferries operate safely. The route is one of the busiest vehicle ferry crossings in the Southern Hemisphere, and the vessels are purpose-built for the conditions. Seasick patches are available on board, and the Marlborough Sounds section at the Picton end of the crossing is sheltered and beautiful regardless of weather.

Location note: The two terminals are approximately 2km apart in Wellington. Both are north of the CBD, accessible by taxi or shuttle from the city centre.

Both operators’ fares vary significantly depending on how far in advance you book and the season. The ranges above reflect typical pricing; early booking (4-6 weeks) consistently yields the lower end of the range. Last-minute foot passenger tickets (same-week) are available but vehicle bookings close when vehicle space is full.

Book the Wellington-Picton Interislander crossing — options include foot passenger, car, and campervan.

Timetable overview (2026)

Both operators run multiple sailings per day in each direction. Typical departure windows:

Wellington → Picton: Early morning (~6-8am), mid-morning (~10am-12pm), afternoon (~2-4pm), sometimes evening in peak season.

Picton → Wellington: Similar spread. Check exact times when booking — specific times change seasonally.

Travel time: Budget 3h30-3h45 door-to-door on the vessel. Add travel time to/from Wellington city centre (20-30 minutes to either terminal) and check-in time (45-60 minutes before departure for vehicles, 30 minutes for foot passengers).

Total Wellington-to-Picton day: Arriving at Wellington terminal at 8am for a 9am sailing, you arrive Picton around 12:30pm. Feasible to reach Christchurch (3.5-4 hours further south) by early evening — but it is a long day.

Booking strategy

Peak season (November-February, school holidays, Easter): Book vehicles 4-8 weeks ahead, especially for campervans. The vehicle deck fills from the largest vehicles inward; campervans and large motorhomes need to book earliest.

Shoulder season (March-May, September-October): 2-3 weeks ahead is usually sufficient.

Off-peak (June-August): Often possible to book 1-2 weeks ahead, but morning sailings in school holidays still fill.

Foot passengers: Much more flexibility — typically bookable a few days ahead in all seasons.

Flexibility vs. savings: Both operators offer cheaper fares for fully non-refundable bookings. If your travel dates are firm, this is worth it. If your road trip timing is fluid, book a flexible fare (the price difference is typically NZD 30-60 per booking) — weather delays or a detour that catches you can make a schedule change necessary.

What happens if the crossing is rough

Cook Strait can produce swells of 3-6 metres in winter storms. Both operators assess sea conditions before every sailing. In genuinely hazardous conditions, sailings are cancelled and rescheduled.

What to do if cancelled: Both operators have policies for rebooking cancelled sailings. Accommodation bookings in Picton or Wellington that cannot be kept due to cancellation may need to be renegotiated — travel insurance is recommended, particularly for peak season travel.

Rough weather tips:

  • Eat lightly before boarding
  • Sit in the middle of the vessel (least movement)
  • Stay above deck if weather permits — fresh air helps
  • Seasickness patches (Scopolamine) available at pharmacies and sometimes on board — apply 2-4 hours before boarding for best effect
  • Antihistamine tablets (Avomine, Stugeron) available at NZ pharmacies without prescription

The Marlborough Sounds section (approximately the final 45 minutes of the Picton approach) is sheltered water regardless of conditions. Many passengers find the rough section manageable knowing the calm ending is coming.

Taking a campervan on the ferry

Booking: Make the campervan booking explicit — select the vehicle height and length carefully. Standard campervan categories: under 5.5m, 5.5-7.3m, 7.3m+. Excess height (above 2.5m-2.8m) may attract a surcharge.

Loading: Vehicles are loaded and unloaded by the ferry crew. You drive on under crew direction; do not leave anything loose in or on the vehicle that could move in swell.

Access during crossing: You cannot access the vehicle deck during the crossing. Pack anything you need (medication, snacks, entertainment, passports) in a bag you carry to the passenger decks.

Diesel vs petrol: Most campervans are diesel; refuel in Wellington or Picton as there is no fuel on the ferry.

The flying alternative

Wellington to Christchurch by air: approximately 1 hour, typically NZD 80-180 (USD 48-108 / EUR 44-99) depending on advance booking. One-way flexible fares NZD 150-250.

When flying makes sense:

  • Solo traveller (no vehicle to move — ferry + car hire each island can be cheaper than one-way vehicle rental)
  • Time-pressured itineraries (saves 4-5 hours vs ferry + drive)
  • When you are not planning to drive the full length of New Zealand and can hire separate vehicles on each island

When flying does not make sense:

  • You have a campervan or rental car that must cross
  • Your itinerary requires passing through the Marlborough wine region, Kaikoura coast, or Marlborough Sounds (the ferry journey IS part of the scenery)
  • You want the experience of the crossing itself — it is genuinely dramatic and beautiful

See the domestic flights guide for airline options and booking strategy.

Picton arrival: first 2 hours

Picton is a small, charming town with limited facilities. On arrival:

  • Fuel up (there is a petrol station near the terminal)
  • Get groceries if heading to Marlborough Sounds or Kaikoura (the road south is beautiful but limited shops)
  • The SH1 south toward Kaikoura and Christchurch is immediately accessible — no navigation complexity

Marlborough diversion: The ferry terminal at Picton puts you at the doorstep of Marlborough wine country (Blenheim is 28km south). If the timing works, stopping for a winery lunch in Marlborough before continuing south is one of the most pleasantly spontaneous combinations in New Zealand travel.

Wellington departure: what to do the morning of

Terminal arrival times:

  • Interislander: 45-60 minutes before departure for vehicles
  • Bluebridge: 45 minutes before departure for vehicles
  • Foot passengers: 30 minutes before both operators

Parking in Wellington while waiting: The Interislander terminal has a holding area. In the city, Te Papa car park (on the waterfront, 10-15 minutes from the terminal) is a sensible place to park if you arrive early and want to use the morning.

Wellington to terminal: By taxi/Uber, approximately NZD 20-30 from the CBD. There is no dedicated public transit service directly to the Interislander terminal (though the Bluebridge terminal is slightly closer to the CBD/Courtenay Place area, walkable with light luggage).

Frequently asked questions about the Cook Strait ferry

Can I take a bicycle on the ferry?

Yes. Both operators accommodate bicycles at a small surcharge (approximately NZD 20-30). Cycles are loaded in the vehicle deck separately — check in at the terminal and follow crew direction.

Is there Wi-Fi on board?

Both operators offer Wi-Fi on board, though speed varies. Streaming video is generally not practical, but browsing and messaging works adequately. For a 3.5-hour crossing, offline entertainment is recommended.

Can I walk on without booking?

Foot passengers can walk on without advance booking if space is available. In peak season, it is advisable to book a day or two ahead for foot passages to guarantee a specific sailing. Vehicle spaces cannot be assumed — book vehicles in advance.

What should I do if my campervan is too tall?

Some campervans exceed the standard height limits (2.5-2.8m). Both operators have vehicle height categories with surcharges for taller vehicles. Measure your campervan’s actual height at the highest point (roof rack, air vents) before booking and select the correct category to avoid reclassification charges at the terminal.

Is the Marlborough Sounds section of the crossing worth seeing?

Absolutely. The final 40 minutes approaching Picton through the Queen Charlotte Sound is one of the most beautiful ferry approaches in the world. If you have been inside the terminal watching movies, come out on deck for the final approach.
