1. Fiordland & the Southern Lakes — 10-14 days
Milford is worth it, but not the way most people do it. Doubtful Sound, Wanaka over Queenstown on the nights that matter, and drive timings nobody agrees on. → Full route
2. West Coast End-to-End — 7-10 days
A committing single road, NZ's wettest region, and what five rushed days actually costs you versus ten. Glaciers, rainforest, greenstone — the West Coast doesn't do half measures. → Full route
3. Central Otago — 5-7 days
Beyond Queenstown: the Otago Central Rail Trail, Alexandra fruit growing, Bannockburn wine. Wanaka over Queenstown if you only care about the lake. → Full route
4. Christchurch to Queenstown — 7-9 days
The Central Lakes way via Tekapo, Pukaki, and Wanaka. The drive every South Island itinerary should start with. → Full route
5. Marlborough Sounds & Wine — 3-4 days
Picton is where most South Island trips begin. Queen Charlotte Track by boat and bike, then 15 cellar doors in a 5km radius around Renwick. → Full route
6. Nelson Tasman — 4-5 days
Nelson's arts and food scene plus Abel Tasman National Park. Base in Motueka for the park, Nelson for the markets. → Full route
7. Top of the South — 5-7 days
Picton, Nelson, Blenheim, and Golden Bay as a triangle. Golden Bay is the outlier — 2.5 hours over Tākaka Hill — worth it, but not as a day trip.
8. Dunedin, Catlins & Invercargill — 4-5 days
The deep south. Dunedin's architecture, the Catlins' untouched coast, Invercargill as a gateway to Stewart Island. Quiet roads, big skies.
9. Lewis Pass & Arthur's Pass — 3-4 days
The alpine crossing between Canterbury and the West Coast. Two passes, one road, and the best mountain driving in the South Island.
10. Picton to Canterbury — 3-4 days
The ferry-arrival route most people drive through without stopping. Kaikōura for whales — the Peninsula Walkway is worth the stop.
FAQ
Which of these fits into a genuine 1-week trip vs needing 10+ days?
Marlborough Sounds & Wine (3-4 days), Nelson Tasman (4-5 days), Lewis Pass & Arthur's Pass (3-4 days) and Picton to Canterbury (3-4 days) all fit inside a genuine week. Fiordland & the Southern Lakes needs the full 10-14 days to do properly, cramming Milford, Doubtful and Wanaka into a week means cutting one of them, not enjoying all three lightly.
Is Golden Bay worth the detour if I'm doing the Top of the South route?
Worth it if you have at least two nights to give it, not as a day trip bolted onto the rest of the Top of the South loop. It's 2.5 hours over Takaka Hill each way, so a same-day there-and-back turns into more driving than time spent in Golden Bay itself.
How does Christchurch to Queenstown compare to Picton to Canterbury for a first South Island trip?
Christchurch to Queenstown via Tekapo, Pukaki and Wanaka is the better first-timer route since it's built around the Central Lakes drive most South Island itineraries lead with. Picton to Canterbury suits anyone arriving by ferry who wants Kaikōura's whale watching on day one rather than driving through it, which is what most people do without stopping.
