Nautical Miles

Earn Nautical Dollars every time you sail with Interislander and use them to get discounted ferry travel, cheap deals, and priority unloading!

Cheap Cook Strait ferry travel with Interislander Nautical Miles membership


Are you a frequent Interislander traveller?  Nautical Miles will reward you with discounted upgrades, earning Nautical Dollars for future travel, and more.

If you’re a regular traveller, your membership will quickly pay for itself – membership costs only $25 per year.


Look at these great benefits:

  • Earn, then cash in your Nautical Dollars to offset or completely cover future travel. You’ll earn one Nautical Dollar for every ten dollars you spend with Interislander. 
  • You can upgrade for just $40 to the comfy Interislander Plus lounges (normal price $55).  Food and drink is included, making this a popular option for those over 18 years of age.
  • Members can choose late check-in and arrive 15 mins later than normal (30 mins if you’re walking on, or 45 mins if you’re driving), or get off the ship faster with priority disembarking for vehicle passengers*. 
  • Nautical Miles foot passengers are also entitled to take an extra piece of luggage: three pieces instead of the usual two.

* Priority disembarking check-in is one hour before departure. Priority disembarking cannot be used in conjunction with late check-in.

If you’re travelling with your car, your Priority rear vision hanger will help get you off the ship as quickly as possible. We can’t guarantee priority unloading every time, but we always do what we can to make sure that Nautical Miles members are amongst the first vehicle passengers off the ship.
