Halfmoon Bay: The Heart of Stewart Island
Halfmoon Bay is home to Oban, the only town on Stewart Island and New Zealand’s southernmost settlement. Curved like its namesake, the bay shelters a small fishing village surrounded by native bush and abundant birdlife. Everything on Stewart Island effectively starts here. That includes hiking tracks, boat trips, and some of the best wild kiwi spotting anywhere in the country.
This guide covers Halfmoon Bay itself, how to get there, and what to do once you’ve arrived. For a wider look at Stewart Island’s attractions and tours, our Stewart Island guide covers more of the island beyond this one bay.

Where Halfmoon Bay Is and How to Get There
Halfmoon Bay sits on the eastern side of Stewart Island, New Zealand’s third-largest island, at the very bottom of the country. Getting there means either a flight or a boat. The Stewart Island ferry runs from Bluff, at the southern tip of the South Island. It takes about an hour to cross Foveaux Strait.
Flights are also available from Invercargill, landing at a small airstrip a short drive from Oban. The ferry crossing can get choppy in rough weather. Travellers prone to seasickness may prefer flying instead. Either way, book ahead during summer, when both services run at their busiest.
Once you arrive, you won’t need a car. The town is small enough to explore entirely on foot, and most accommodation, shops, and tour departures sit within easy walking distance of the wharf.
Oban: Stewart Island’s Only Town
Oban Stewart Island sits right on Halfmoon Bay. It’s home to almost the entire island’s population, around 400 people. It’s genuinely small. A handful of shops, cafes, and accommodation options all sit within a five-minute walk of the wharf. Despite its size, Oban has everything a visitor actually needs, from a general store to a pub with genuine local character.
The town blends its fishing heritage with a growing tourism industry, though it never feels overrun. Houses sit nestled among lush native vegetation, and short walking tracks lead out from town into surrounding forest within minutes. It’s a rare example of a settlement that hasn’t outgrown its surroundings.
The South Sea Hotel, right on the waterfront, has served as the town’s social hub for generations. It’s worth a stop even if you’re not staying overnight, since it captures Oban’s relaxed, unpretentious character better than almost anywhere else on the island.
Stewart Island Kiwi Spotting
Stewart Island kiwi spotting draws visitors from around the world. Halfmoon Bay is the usual starting point for guided tours. Unlike most of mainland New Zealand, where kiwi are almost never seen outside a nocturnal enclosure, Stewart Island’s kiwi population is genuinely visible in the wild. Sightings sometimes happen even during the day.
Guided evening tours head out from Oban to nearby beaches. Guides know the routines of local birds well enough to offer a realistic chance of a sighting. It’s one of the most reliable places in the country for this kind of encounter. Our guide to New Zealand birds covers more on where to see kiwi and other native species across the country.
Bring warm clothing and a torch with a red filter if you’re joining an evening tour, since white light can disturb the birds. Patience matters too. Even on Stewart Island, a sighting is never guaranteed, though the odds here beat anywhere else in New Zealand.
Ulva Island and Paterson Inlet
South of Oban, Paterson Inlet nearly cuts Stewart Island in half. It’s a popular spot for boating, fishing, and diving. Within the inlet sits Ulva Island, a predator-free sanctuary reachable by a short water taxi from Halfmoon Bay. Introduced pests have never established here, or have been fully removed. As a result, Ulva Island supports birdlife rarely seen so easily elsewhere in New Zealand.
Saddlebacks, kākā, and native robins are common sights along Ulva Island’s walking tracks. They often approach visitors with little fear. It’s an easy half-day trip from Halfmoon Bay. Few wildlife experiences on Stewart Island reward so little effort with so much to see.
The Rakiura Track
The Rakiura Track, one of New Zealand’s official Great Walks, begins a short drive from Halfmoon Bay at Lee Bay. It’s a 32-kilometre loop, typically completed over three days. Coastal forest, beaches, and genuine backcountry scenery define the route. Because it’s a loop, no shuttle arrangements are needed at the end. That simplifies planning considerably.
Compared with some of the more polished Great Walks on the mainland, the Rakiura Track feels rougher and more remote. Muddier sections and a real sense of isolation set it apart. Our guide to New Zealand’s Great Walks covers the Rakiura Track alongside six other standout multi-day hikes across both islands.
Planning Your Visit
Halfmoon Bay works best as part of a dedicated Stewart Island stop within a wider South Island itinerary, rather than a rushed day trip. A self-drive New Zealand tour can include a Bluff ferry crossing as part of a longer southern route. A South Island tour is a solid alternative too. It suits travellers who’d rather have local knowledge on hand for the wider region.
