Which Queen Charlotte Sound scenic cruise suits your day

The mail boat leaves at 1:30 PM. From 1 October it sails Monday to Saturday, and from 1 May to 30 September it runs on Monday, Wednesday and Friday only.⁸ On the listing this site books, the trip lasts 4 hours and the skipper hands out post, groceries and freight at homes around the sound. The listing names it a mail boat cruise from Picton, and the skipper is also your guide for the afternoon.

The route moves to a different part of the sound each day, following the deliveries.¹² If time allows, the boat stops briefly somewhere on the way, and you learn the day's route when you check in.¹³ The listing says the boat depends on numbers, from a 9-seat single-hull boat to a 90-seat catamaran with an upper deck; that differs from the 12-seat to 150-seat range the operator gives for its whole fleet.⁴

This is the trip for travelers who like to see how a place works. You watch the skipper bring the boat alongside a private jetty, hand over a mail bag and a box of groceries, and pull away again, often with a wave from someone who has been waiting at the end of the pier. It is less polished than a scenic cruise, and that is its charm.

If wildlife is your priority, choose a trip built around it. The wildlife operator's 4-hour tour searches the sound for dolphins and then lands you on Motuara Island, a sanctuary cleared of introduced pests in the early 1990s.^15,2 The operator names the dolphins of the Marlborough Sounds as dusky, bottlenose, common, orca and the rare Hector's.²⁵

On the island, a bird viewing station sits about 5 minutes from the jetty, and a moderate track of about 800m climbs to the highest point at 128m.²⁶ The water taxi company that also visits the island gives you around 1.5 hours ashore.²⁷ Walk slowly, stop often and listen: the birds are easier to hear than to see in the bush.

Sightings are never guaranteed on any cruise, so treat dolphins as a bonus rather than a promise. One operator is so sure of the calm water that it refunds the full cost of the tour if a guest gets seasick.²⁸ Bring binoculars, a warm layer for the island lookout and shoes with some grip for the track.

The mail boat is not the only boat that earns its living delivering. The water taxi company runs a delivery cruise at 9:30 AM and 1:30 PM, about 3.5 hours long, dropping people and supplies at private homes, remote resorts and the jetties of the Queen Charlotte Track.^7,14,34 Along the way the crew watch for seals, penguins, dolphins, stingrays and rare seabirds.³⁴

The difference is the mail itself. The mail boat's operator says it holds the only official licence from New Zealand Post to deliver rural mail by water on Queen Charlotte Sound.³⁵ If the romance of the post bag appeals, that is the boat to take; if you simply want the behind-the-scenes view at a different time of day, the delivery cruise works just as well.

Both trips change their route with the day's errands, and both give you a skipper's commentary rather than a recorded one. The morning delivery run suits travelers who want the afternoon free, while the afternoon mail boat suits those arriving on a morning ferry. Either way, check in early and sit on the side facing the shore.
