21-day New Zealand itinerary: both islands, Catlins, Stewart Island

Three weeks in New Zealand — what changes when you slow down

Twenty-one days changes everything about how you travel New Zealand. The pressure dissolves. You spend two nights in most places rather than one. You stop at the Moeraki Boulders not because they’re on the itinerary but because you happen to be passing and have time. You get to the Catlins — the wild, tourism-bypassed southern coast that most visitors never see — and spend two nights rather than rushing through in a single long drive.

This is not a “best of New Zealand” greatest hits run. That’s the 14-day itinerary. This is what you do when you want to actually understand the country: the wild southern sections, the quirky steampunk town of Oamaru, a night on Stewart Island/Rakiura where the kiwi walk through the forest 100 metres from the pub. Three weeks is enough to cover North Island highlights, Kaikoura, the West Coast glaciers, Queenstown, the Catlins, and Stewart Island without arriving anywhere exhausted.

The itinerary uses a car throughout (including on the Interislander ferry). One-way car rental (Auckland pick-up, Christchurch or Queenstown drop-off) is the practical solution.

Christchurch afternoon: Punting on the Avon (NZD 35 / USD 21 / EUR 19), the Cardboard Cathedral, Re:START container mall, Botanic Gardens.

Hooker Valley Track (3 hours return, flat, ends at glacier terminal lake with floating icebergs) — free, no booking, genuinely spectacular.

Day 15: Mt Cook → West Coast → Franz Josef

Morning: Mt Cook scenic flight (helicopter or ski plane over Aoraki and the Tasman Glacier). The Mt Cook ski plane and helicopter glacier combo is the best value (NZD 435–550 / USD 261–330 / EUR 240–303). Only if weather permits — book with flexibility.
Drive west over Haast Pass — the most dramatic inland-to-west-coast drive in New Zealand (3h30). The Haast Pass road descends through temperate rainforest to the Tasman Sea.
Arrive Franz Josef Town mid-afternoon. Brief walk to the glacier viewpoint on the Franz Josef Glacier Walk (free, 1.5 hours return).
Accommodation: Franz Josef Town. Range from backpacker NZD 35/dorm to mid-range lodge NZD 180–260 / USD 108–156 / EUR 99–143.
Cost: NZD 300–600 / USD 180–360 / EUR 165–330.

Day 16: Franz Josef — glacier heli-hike

The helicopter glacier hike is the signature West Coast experience. The Franz Josef 2.5-hour glacier heli-hike lands on the upper snowfield and walks through the ice for 2 hours with crampons and guides provided. NZD 445–535 / USD 267–321 / EUR 245–294. Book with a weather cancellation policy — West Coast weather changes fast.
Alternative: Fox Glacier (30 min south) has a similar heli-hike. Or the Lake Mapourika canoe cruise if you’re not a heights person.
Afternoon: West Coast Wildlife Centre (kiwi, tuatara, NZD 30 / USD 18 / EUR 16) and Hokitika Gorge day trip (1 hour north, extraordinary turquoise water, NZD 0 entry).
Cost: NZD 350–600 / USD 210–360 / EUR 193–330.

Day 17: West Coast → Wanaka — 5 hours

Drive south through Haast (fuel up — the next reliable fuel is 120 km away) and over the Haast Pass in reverse toward Wanaka. Alternatively, the coastal road south to Haast via Knights Point and Lake Paringa is dramatic and slower.
Arrive Wanaka afternoon. Walk to the Wanaka Tree, lakefront stroll, coffee.
Evening: Roy’s Peak is a popular but strenuous hike (5 hours return, 1,578m summit). For a sunset perspective without the effort, the Diamond Lake loop (1.5 hours) gives excellent lake views.
Accommodation: Wanaka. Mid-range hotels NZD 180–280 / USD 108–168 / EUR 99–154.
Cost: NZD 80–200 / USD 48–120 / EUR 44–110.

Day 18: Wanaka → Queenstown — 1 hour via Crown Range

Scenic morning drive over the Crown Range (New Zealand’s highest sealed road). Stop at the Crown Range summit for the view down into the Wakatipu Basin.
Queenstown: Adventure capital. Shotover Jet (NZD 169 / USD 101 / EUR 93), Nevis Bungy (NZD 275 / USD 165 / EUR 152), Skyline gondola and luge (NZD 50–75), or Central Otago wine tour through Gibbston Valley (NZD 155–185).
Evening: Queenstown proper — Fergburger, Rata restaurant, lakefront bars.
Accommodation: Queenstown. Wide range from backpacker to luxury. Mid-range NZD 200–350 / USD 120–210 / EUR 110–193.
Cost: NZD 200–500 / USD 120–300 / EUR 110–275.

Day 19: Milford Sound day trip

The Milford Sound fly-cruise-fly from Queenstown is the best use of this day — scenic flight over Fiordland mountains, 2-hour nature cruise, fly back. NZD 565–720 / USD 339–432 / EUR 311–396.
Alternatively: Drive from Queenstown to Te Anau (1.5 hours), then Milford (1.5 hours). Takes the entire day but is cheaper — Milford cruise from the jetty starts at NZD 75–95 for a basic nature cruise.
Milford Sound in rain: go anyway. The fiord receives 7,000mm of rain annually — waterfalls multiply 10-fold in heavy rain, and the mist creates an atmosphere that clear days lack entirely.
Sleep: Queenstown or base in Te Anau if doing Doubtful Sound tomorrow.
Cost: NZD 400–750 / USD 240–450 / EUR 220–413.

Day 20: Queenstown → Dunedin → the Catlins — 3.5 hours

Drive east from Queenstown to Dunedin via the Clutha Valley (3 hours). Stop at the Moeraki Boulders on SH1 (15 min north of Oamaru) — spherical concretion boulders on a beach, geologically remarkable, photogenic.
Oamaru: The steampunk capital of New Zealand (45 min north of Dunedin). Blue penguin colony evening viewing (NZD 35–45 / USD 21–27 / EUR 19–25, penguins return from sea daily at dusk).
Alternatively: Dunedin itself — Otago Peninsula for yellow-eyed penguins and the royal albatross colony at Taiaroa Head. The Dunedin royal albatross and Otago Peninsula tour covers both wildlife sites efficiently (NZD 180–220 / USD 108–132 / EUR 99–121).
Continue south to the Catlins (1.5 hours from Dunedin). Sleep in Owaka or Curio Bay.
Cost: NZD 200–350 / USD 120–210 / EUR 110–193.

Day 21: The Catlins → Stewart Island — or fly out from Invercargill

Morning: Catlins highlights — Nugget Point Lighthouse (45-min return walk, sea lions and fur seals below), Curio Bay fossilised forest (free, low tide best), Cathedral Caves (tidal access, NZD 10 / USD 6 / EUR 5).
Drive to Invercargill (1.5 hours). Option: Catch the passenger ferry from Bluff to Stewart Island/Rakiura (1 hour, NZD 100–130 return). Stewart Island is one of New Zealand’s last true wild places — 85% national park, 400 permanent residents, and the world’s best chance of seeing a wild kiwi in daylight on Mason Bay.
Stewart Island overnight: Stewart Island wild kiwi encounter at night (guided, NZD 120–160 / USD 72–96 / EUR 66–88). Ulva Island open sanctuary for daytime birdwatching.
Or: Fly home from Invercargill (via Christchurch or Wellington) if this is your final day.
Cost: NZD 200–400 / USD 120–240 / EUR 110–220.

What this itinerary honestly skips

Abel Tasman National Park. Golden sand beaches, world-class kayaking, the Abel Tasman Coast Track — genuinely excellent and frustratingly far off the main South Island spine. Adding it requires 2 nights in Nelson or Marahau and restructures the West Coast section. Best addressed on a dedicated 7-day South Island itinerary that starts with Christchurch and builds west.

Napier and Hawke’s Bay. The Art Deco city and Cape Kidnappers gannet colony are excellent but require a significant North Island detour east from the main SH1 spine. Days 6–8 could be restructured to include Napier instead of doubling back through Rotorua.

The Coromandel Peninsula. Cathedral Cove and Hot Water Beach deserve 2 nights. They can replace the Bay of Islands section if you prefer coastal hiking over boat-based bay exploration.

When to do this itinerary

November to March: Best conditions for the Tongariro Crossing, Great Walks, and West Coast glacier flights. Book 2–3 months ahead for peak months.

April to May: Autumn foliage in Central Otago, quieter roads, 20–30% cheaper accommodation. The Catlins is particularly beautiful with fewer visitors. Tongariro Crossing should be checked for conditions.

June to August: West Coast glacier heli-hikes are reduced by low cloud more frequently. Tongariro Crossing not recommended without alpine experience. But: Queenstown ski season is excellent, Milford Sound is dramatic, and Stewart Island kiwi encounters run year-round. Adjust Days 7–8 for ski days rather than the crossing.
