Nautical Miles gives members the opportunity to earn free travel simply by sailing with Interislander.

Earn Nautical Dollars

As a Nautical Miles member, you’ll earn one Nautical Dollar for every ten dollars you spend with Interislander. The more you travel, the more you earn. You can then cash your Nautical Dollars in for free travel across the Cook Strait.

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

Upgrade for less

You can also upgrade for just $30 to the comfy Plus Lounges (normal price $45). Relax in comfortable seating and be entertained with Sky TV, newspapers and magazines whilst you enjoy complimentary beer, wine, tea, coffee and food. Upgrades to the Plus lounges are subject to availability, so it is best to purchase them at the time of booking online. However, if there are spare seats then these will be on sale at the terminal or in the onboard shop.

All passengers over the age of 18 years listed on a Nautical Miles members booking receive the same discounts for Plus Lounges. Under 18s are not allowed in the Plus Lounges.

Enjoy VIP treatment

Nautical Miles members can check in a full 15 minutes later than other passengers. This means checking in 30 minutes before sailing time for foot passengers and 45 minutes for vehicle passengers. Nautical Miles foot passengers are also entitled to take an extra piece of luggage: three pieces instead of the usual two.

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.

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