New Zealand's South Island: a guide to one of the world's great road trips
Published 24 September 2026
How to plan one of the world's great road trips
Few people question whether New Zealand's South Island deserves its reputation as a road trip. The more useful question is how to plan one so that the holiday is spent in the landscape rather than behind a windscreen, and that is where most itineraries go wrong.
The short answer is this: allow at least two weeks for the South Island on its own, drive it in one direction rather than as a loop, keep most driving days to three or four hours, and stay two nights in most places. Fly into the start and out of the finish, typically Nelson in the north and Queenstown in the south. Treat Milford Sound as an excursion from Te Anau rather than a day trip from Queenstown, and build in a spare day on the West Coast, where weather decides what you can do.
The reason for this caution is simple. Distances look modest on a map but take longer in practice: the open-road speed limit is 100 km/h, there are very few dual carriageways outside the cities, many rural roads have one-lane bridges, and the Southern Alps stand between most of the places you will want to see. A well-paced itinerary accepts those constraints rather than fighting them.
Marcelle Hoff, owner of Expressions Holidays says: 'Most visitors try to cover the South Island in ten days, drive six or seven hours at a stretch and see Milford Sound through a coach window after a pre-dawn start from Queenstown. A well-planned trip covers less ground, stays two nights at a time in lodges chosen for their setting, and reaches the fiords, glaciers and passes when the light and the traffic are on its side'.

Why the South Island is regarded as one of the world's great road trips
The South Island's appeal lies in how quickly the landscape changes. The Southern Alps run almost its full length, rising to Aoraki/Mount Cook at 3,724 metres, and only three roads cross the main divide: the Lewis Pass (907 metres), Arthur's Pass (920 metres) and the Haast Pass (562 metres). A single journey can take in the vineyards of Marlborough, the whale-watching coast at Kaikoura, the beech forest and tussock of Arthur's Pass, the rainforest and glaciers of the West Coast, the lakes of Wanaka and Queenstown, and the fiords of the far south-west. Few comparable road journeys offer that range within a fortnight, and the drive between places is often part of the point rather than an interval.

What driving in the South Island is actually like
For British drivers, New Zealand is straightforward in one respect: traffic keeps left, and a current UK licence in English is accepted for visitors. Road surfaces on the state highways are generally good. What takes adjustment is pace. Most routes are single carriageway, often winding and hilly, and one-lane bridges are common; signs show which direction has priority, and giving way is routine rather than exceptional. Towns and fuel stops thin out considerably on the West Coast and over the Haast Pass, and mobile coverage is patchy in the mountains. In practice, an average of around 60 to 70 km/h including stops is a more realistic planning figure than the speed limit suggests. Expressions includes a Hertz four-wheel-drive (Ford Escape or equivalent) as standard, which suits the terrain and gives a better view over the roadside.

Is a South Island road trip too much driving?
It can be, and it is worth saying so plainly. The common mistake is to see the island's highlights as a checklist and connect them all, which produces long days, early starts and little time at each stop. The remedy is structural: fewer bases, two nights in most of them, and driving days kept to a morning or an afternoon with stops built in. Some legs cannot be shortened; the run from Franz Josef over the Haast Pass to Wanaka is best treated as a full day. Where a leg adds little, it can be removed. A domestic flight between Christchurch and Queenstown, for instance, saves a long day for those who would rather spend it on the ground, and the TranzAlpine train between Christchurch and Greymouth is an alternative way across the Alps.

How to plan the route, and how long to allow
The most rewarding shape for a first visit runs north to south. Start in Nelson and the Abel Tasman National Park, cross to the Marlborough wine country around Blenheim, follow the coast to Kaikoura, then turn inland from Christchurch over Arthur's Pass to the West Coast glaciers. From Franz Josef, the road runs south over the Haast Pass to Wanaka and Queenstown. Our Best of New Zealand's South Island tour follows exactly this route over 14 nights, from about £4,990 per person including economy flights from London. A popular variation substitutes or adds the Mackenzie Country and Aoraki/Mount Cook, with a night at The Hermitage. For those combining both islands, the Interislander ferry between Wellington and Picton takes about three hours, or a short domestic flight does the same job; our 21-night New Zealand Explorer tour links the two.

Milford Sound: how to do it well, and how most people do it
Milford Sound illustrates the difference between a good and an average itinerary more clearly than anywhere else. Queenstown and Milford look close on a map, but the road runs the long way round via Te Anau: roughly 288 km each way, and the Department of Conservation estimates 12 to 14 hours for the return trip. From Te Anau, the Milford Road is 119 km, with no services along the way and a non-stop drive of at least two hours. It climbs to the 1.2 km Homer Tunnel, completed in 1953, where traffic lights can cause delays of up to 20 minutes in the busy October to April season. In winter and spring the road may close for avalanche control. The better approach is to stay in Te Anau, at Fiordland Lodge for example, and time the drive to avoid the coach traffic, which heads towards Milford in the morning and back in the afternoon. Alternatively, fly from Queenstown in around 40 minutes, or choose an overnight cruise on Doubtful Sound aboard the Fiordland Navigator.

How Expressions Holidays organises a South Island road trip
Every Expressions holiday to New Zealand is tailor-made, and the South Island tour is a starting point rather than a fixed package. We include international and domestic flights, a private transfer on arrival, your hire car and accommodation chosen for the character of each location. On our suggested route, that might mean The Resurgence or Bronte Lodge near Nelson, Marlborough Lodge among the Blenheim vineyards, Hapuku Lodge at Kaikoura, The George in Christchurch, Wilderness Lodge at Arthur's Pass with its working sheep farm, Te Waonui Forest Retreat at Franz Josef, Mahu Whenua near Wanaka and The Rees or Azur Lodge on Lake Wakatipu. We will advise on where to add a night, where a flight makes more sense than a drive, and how to time Milford Sound. Your holiday is handled throughout by one consultant, and comes with our handcrafted regional notes and ATOL protection.
