Schematic locator, not to scale. The highlighted area runs the length of the West Coast, Westport down to Haast.
SH6 down the West Coast is a committing single road: there's no faster alternate route once you're on it, so a weather delay or a late start costs you the same stretch of afternoon back, with no detour to make up time. Franz Josef and Fox Glacier sit about 23km apart, roughly 20 minutes on a clear day, but Franz Josef down to Wanaka via Haast Pass is a different order of drive: a little over 288km and a genuine 3.5 to 4 hours without stopping (some route calculators put it closer to 4.5 once you slow for the pass's tighter sections), and it's worth treating as its own full day rather than tacking it onto a bigger loop. Seven days is the realistic middle ground for driving the whole coast, from around Westport/Punakaiki down to Haast. Five days is a whirlwind that leaves no room for the weather this coast actually gets, and 10-14 gives real downtime, including margin for the one thing most itineraries never budget for: rain. This is the route for travellers who want the coast itself as the spine of the trip, not just a corridor between Abel Tasman and Queenstown. See the West Coast NZ Mixtape for the themed, stop-by-stop detail this spine leads into.
The driving spine, segment by segment
Break the coast into real legs rather than one abstract "West Coast drive." Westport to Punakaiki is short: about 56km, under an hour, with Pancake Rocks the obvious stop. Punakaiki on to Hokitika adds roughly another 84km and under an hour of driving. Hokitika to Franz Josef is where the road changes character: about 134km and officially just under two hours, but SH6 here runs along valley floors with winding, hilly sections and a string of one-lane bridges, so treat any "1h45" quoted online as the floor, not the target. Franz Josef to Fox Glacier is the shortest, easiest leg on the whole route: about 23km, 20 minutes. Then comes the leg that genuinely needs its own day: Franz Josef to Wanaka via Haast Pass, a little over 288km and 3.5-4 hours with no stops, which in practice runs to 6-8 hours once you add Thunder Creek Falls, the first Lake Wanaka lookout, and lunch. Haast township, roughly 120km south of Fox Glacier and the last real services before Wanaka, is worth treating as a fuel and food checkpoint, not a destination in its own right.
New Zealand's wettest region, and what five rushed days actually costs you
The West Coast is officially New Zealand's wettest region, and NIWA's own regional climatology is blunt about why: the prevailing westerly airflow runs straight into the Southern Alps, and the mountains wring the moisture out of it. Low-elevation coastal towns like Hokitika and Franz Josef typically get 2,000-3,000mm of rain a year; up in the ranges behind them, some sites regularly exceed 10,000mm, and the Cropp River catchment near Hokitika holds New Zealand's highest recorded annual rainfall, over 18,000mm in a single year. Practically, that means rain on this coast isn't a risk to plan around so much as a near-certainty to plan for, and it's the actual reason seven days beats five, not just a rounder number. Five days leaves no spare day: if a washout, a closed pass, or a grounded glacier heli-hike eats a single afternoon, something on a five-day itinerary has to be cut outright, usually either Punakaiki or one of the two glacier towns, because there's no slack left to absorb the loss. That's the honest downgrade worth naming here: treating five days as a genuine way to do the full coast, rather than the rushed compromise it actually is, oversells what's realistic on New Zealand's wettest stretch of road. Seven days, or better, ten to fourteen, is what actually buys you a spare day.
Haast Pass: the honest closure picture
Haast Pass, the SH6 section between Haast and Makarora/Wanaka, does close, and the causes are exactly what you'd expect on this coast: heavy rain triggering slips, storm damage to the road surface or bridge approaches, and occasionally snow or ice on the higher sections through the cooler months. It's not a constant risk, but it's a real one: a stretch between Haast and Lake Moeraki was closed in November 2025 after slips caused by heavy rain, and a NZ$5 million resilience project was announced in December 2025 (current as of writing) specifically to protect the Haast River bridge at the Gates of Haast from ongoing river erosion that's been worsening since Cyclone Fehi damaged the site's scour protection back in 2018. NZTA's own advice is plain: check the Journey Planner the morning you intend to drive it, not the night before, since conditions on an exposed single road like this can change overnight.
Seven days buys you one spare day for weather on New Zealand's wettest coast; five days buys you none, which is the real reason five is a rush and not just a preference.
The bit nobody publishes: Fox Glacier Motors is the last fuel stop for about 120km heading south to Haast, and Haast itself has limited accommodation, a handful of motels and a lodge or two, not a town with much spare capacity. An unplanned extra night from a pass closure or a genuine washout isn't just an inconvenience, it can mean a hard search for a bed in a town with maybe a few dozen rooms total, at whatever rate is left by the time you're asking. Fill the tank at Fox Glacier regardless of what the gauge says, and if you're travelling shoulder or peak season, treat "what if I get stuck a night near Haast" as a real question with an answer, not a hypothetical.
Worth doing as a dedicated spine if you can give it seven days and treat the Haast Pass leg as its own day, not a bolt-on to a bigger Queenstown loop. Worth downgrading to a shorter regional taste, Punakaiki and the glaciers only, skipping the Haast Pass crossing entirely, if you've only got five days and firm bookings waiting in Queenstown or Wanaka, since that's the version of this trip that doesn't gamble against this coast's weather. Not worth attempting as a same-day Franz Josef-to-Wanaka dash without checking NZTA's Journey Planner first: the pass has closed for exactly this kind of storm damage as recently as November 2025, and a closed road doesn't care what time your accommodation check-in is.
How many days do I actually need for the West Coast?
Seven is the realistic middle ground for driving the whole stretch from Westport/Punakaiki down to Haast. Five is doable but rushed, with no buffer for this coast's rainfall; 10-14 gives room for weather delays and rest days, which NIWA's own rainfall data, 2,000-3,000mm a year at low elevation and far more inland, makes more likely here than on most other NZ routes.
Is Haast Pass ever closed?
Yes, periodically, most often after heavy rain triggers slips or storm damage, and occasionally for snow or ice on the higher sections in cooler months. A section between Haast and Lake Moeraki closed for exactly this reason in November 2025, and NZTA is currently running a NZ$5 million resilience project (announced December 2025) to shore up the Haast River bridge against further erosion. Check NZTA's Journey Planner the morning you plan to drive it rather than assuming it's always passable.
Is there fuel between Fox Glacier and Haast?
No, Fox Glacier Motors is the last petrol stop for roughly 120km heading south towards Haast, so fill up in Fox Glacier township regardless of what's left in the tank.
