Stewart Island guide: kiwi spotting, ferries and Ulva Island

Stewart Island/Rakiura is the bit of New Zealand most visitors never reach, which is exactly why it is worth the trip. It has one small town, Oban, a few kilometres of road, a national park that covers most of the island, and some of the best birdlife in the country. It is also one of the few places where you have a real chance of seeing a kiwi in the wild.

This guide covers how to get there, how to see kiwi, how to visit Ulva Island, the best walks and where to stay. Prices and times are as at November 2026 and come from DOC and the operators’ own sites.

Stewart Island at a glance

The island became a national park in 2002, and in 2019 it was accredited as a Dark Sky Sanctuary by the International Dark Sky Association, according to the Stewart Island Promotion Association. The same group says the weather is changeable at 47 degrees south, but that sunshine hours are close to the national average and annual rainfall is less than Auckland’s.

Getting to Stewart Island

You have two choices, and neither involves a car.

Ferry from Bluff. RealNZ runs daily express catamarans between Bluff and Oban. The crossing takes one hour, fares start at $139 one way, and RealNZ advertises return fares from $100.08 each way as at November 2026. Foveaux Strait can be rough, so take seasickness tablets if you need them. RealNZ says to watch for seabirds, including mollymawks (albatross) following the boat.

Bluff is about 28 km and 25 minutes’ drive from Invercargill on our routing estimate, without stops. If you are driving, you can leave the car in Bluff. Book early for summer sailings.

Flight from Invercargill. Stewart Island Flights says the flight takes 20 minutes. Check-in is in the main terminal at Invercargill Airport and closes 30 minutes before departure. The baggage limit is 15 kg checked per person plus one small carry-on, and they cannot carry gas canisters or fuel on scheduled flights. A courtesy van meets you on arrival and drops you at their depot on the Halfmoon Bay waterfront. The Stewart Island Promotion Association also lists flights from Queenstown and Bluff.

Insider tip: fly one way and ferry the other. The flight gives you an aerial view of the island and Foveaux Strait, and the ferry lets you take more luggage on the leg where it matters.

Kiwi spotting on Stewart Island

Rakiura is home to the tokoeka, or southern brown kiwi. Like all kiwi they are mostly nocturnal, shy and well camouflaged, so a guided trip at dusk or after dark gives you the best chance.

RealNZ runs two options as at November 2026:

Wear warm, waterproof layers and sturdy shoes, as you will be out after dark. Keep your voice down and follow the guide’s lead on torches.

DOC says kiwi are occasionally seen during the day on Ulva Island. Treat that as a bonus, not a plan.

Visiting Ulva Island/Te Wharawhara

Ulva Island is the other must-do. It is a small island in Paterson Inlet, a short boat ride from Oban, and DOC describes it as one of the most accessible predator-free sanctuaries in the country.

Here are DOC’s key facts:

• Size: 266.6 hectares of forest dominated by rimu, southern rātā and kāmahi.
• Pest free: rats were eradicated between 1992 and 1996, and the island was declared pest free in 1997.
• Getting there: by water taxi from Golden Bay or Halfmoon Bay to the Post Office Bay wharf.
• Rules: day visits only, no camping, no dogs, no shops, do not play recorded bird calls and do not feed the weka.

The birds are bold and close. DOC lists weka, kākā, kākāriki, tūī, korimako (bellbird), kererū, pīwakawaka (fantail), tīeke (saddleback), tītipounamu (rifleman), brown creeper, Stewart Island robin and mohua (yellowhead).

You can walk Ulva’s tracks on your own with a water taxi, or go guided. RealNZ’s Ulva Island Explorer costs $179 as at November 2026 and includes a guided walk of about 1.5 hours, departing from the Oban wharf. A guide is worth it if you want help finding and naming the birds.

Walks around Oban

You do not need to be a tramper to enjoy the island. DOC lists Oban day walks ranging from 30 minutes to 4 hours, many starting from town, and the Rakiura National Park Visitor Centre at 15 Main Road, Oban can help you choose.

For a longer day, DOC’s Rakiura day walks run 4 hours return (3.8 km) or 7 hours return (9.8 km), timed from the visitor centre.

The Rakiura Track is the island’s Great Walk: a 32 km circuit over 3 days, coastal and forest walking with no alpine passes. DOC requires hut bookings all year, so book before you travel. If you want something serious, the North West Circuit takes 9 to 11 days and is for experienced trampers.

Mud is normal on Rakiura tracks. Pack waterproof boots and gaiters, and allow longer than you think.

When to go and how long to stay

Summer (December to February) brings the longest days but also the most visitors, so book the ferry or flight and your bed early. Spring and autumn are quieter. Winter nights are long, which is good for stargazing and kiwi tours, but the weather is colder.

Two nights is enough for most people:

1. Day 1: ferry or fly over, walk to a lookout near Oban, evening kiwi tour.
2. Day 2: Ulva Island in the morning, an afternoon day walk, dinner in Oban.
3. Day 3: a short walk, then back to Bluff or Invercargill.

Add a spare day if you have a fixed flight out of Invercargill or Queenstown. Foveaux Strait weather can delay sailings and flights.

Where to stay

Everything is in or near Oban, the island’s only town. Choose from motels, lodges, holiday homes and backpackers, and book well ahead for summer weekends, because there are not many beds. Stewart Island Flights notes that many motels and lodges will collect you from its Halfmoon Bay depot, so ask when you book.

If you are walking the Rakiura Track, you will stay in DOC huts or campsites, all of which must be booked year-round.

On the mainland, Invercargill is the easiest base the night before an early ferry or flight. Our campsites guide and South Island campsites list help if you are travelling by campervan and need somewhere to park up near Bluff.

Fitting Stewart Island into a South Island trip

Stewart Island sits at the bottom of the South Island, so it pairs well with the Catlins and Fiordland. From Queenstown, our 14-day South Island road trip passes Te Anau, and you can add Invercargill and Bluff with a couple of extra days. Dunedin to Invercargill is about 206 km and 2 hours 50 minutes on our routing estimate, without stops.
