Why book Interislander
Most visitors do not need a long story here. They need to know whether Interislander fits their trip. The main reasons people choose it are straightforward: it is one of the core Cook Strait operators, it is set up for both foot passengers and vehicles, and its ships are well enough known that some travellers actively prefer one over the other.
If your crossing affects the rest of your New Zealand trip, sailing time matters first and ship preference comes second.
If you are still deciding between operators, compare this page with Bluebridge. If your date is already fixed, the smarter move is usually to check the timetable and then open the booking page in a new tab.
Kaitaki
Kaitaki is the ship most people associate with Interislander. Interislander presents it as its largest ferry and emphasises the onboard mix: restaurants, movie theatres, a bar, lounges, and a children’s area. That makes Kaitaki the more feature-heavy ship in the current setup.
For trip planning, the main question is not whether Kaitaki is “better” in the abstract. It is whether you care about having more public space, more onboard choice, or extras such as the Queen Charlotte Lounge, which Interislander says is only available on Kaitaki. {index=9}
- Best-known Interislander ship for this route
- More onboard facilities and more sense of scale
- Relevant if you care about lounges, family space or a fuller onboard setup
If you want the quieter adult-only lounge option, Kaitaki is the important ship to know. If you mainly care about getting the timing right, go back to the timetable before you book.
Kaiārahi
Kaiārahi is the other Interislander ship you are likely to sail on today. Its official ship page puts more emphasis on practical comfort – lift access from the car decks, accessible facilities, food and passenger areas – rather than trying to sell it as the bigger or flashier vessel.
That makes Kaiārahi useful to understand in a simple way: it is the more compact current Interislander ship, but it is still fully relevant for Wellington – Picton planning. Premium Lounge access can also be added on Kaiārahi, so it is not a stripped-back option just because it feels smaller than Kaitaki.
- Current Interislander ship on Wellington – Picton
- More compact feel than Kaitaki
- Still relevant if you want added comfort through Premium Lounge
If you are comparing ships rather than just operators, the useful contrast is simple: Kaitaki feels broader and more feature-led, while Kaiārahi feels more straightforward and compact.
What to expect on board
Interislander sells the crossing as part of the trip, not just the transfer. That is one reason this operator gets compared so closely with Bluebridge. On the practical side, the most useful differences are these: Kaitaki is the more facility-rich ship, while Kaiārahi is the simpler one; Premium Lounge is available on both; Queen Charlotte Lounge is only on Kaitaki.
If you are sailing on Kaitaki
Expect the fuller onboard mix. This is the ship to care about if cinemas, larger shared areas, or a stronger “main ferry” feel matter to you. :
If you are sailing on Kaiārahi
Expect a more compact ship, but not one that lacks the basics. It still matters for comfort, access and overall route planning.
For most travellers, the wrong sailing time causes more friction than the wrong ship.
Interislander booking tips
The most useful booking order is this:
- Check the timetable first
- Decide whether you are travelling as a foot passenger or with a vehicle
- Book early if you need a car, campervan or trailer space
- Use ship preference only as a secondary filter
This matters even more now because current planning is centred on Kaitaki and Kaiārahi, not the older three-ship setup that still appears on some older pages.
