Driving through New Zealand’s South Island in winter is a breathtaking experience—but one that demands caution, preparation, and smart driving practices. Snow-capped mountains, icy lakes, and winding alpine roads make the region a wonderland for travellers. However, winter weather can also introduce risks such as black ice, poor visibility, and unpredictable road conditions.
If you’re planning to rent a car and explore this stunning part of the country, it’s crucial to know how to drive safely in winter. Whether you’re heading to Queenstown for skiing or exploring the scenic Southern Alps, this guide will help you prepare for a safer winter road trip.
Why Winter Driving in New Zealand’s South Island Demands Extra Care
The South Island is known for its diverse and often extreme weather conditions, especially between June and August, the peak winter months. Temperatures can plunge below freezing, and high-altitude passes like Lindis Pass, Arthur’s Pass, and Haast Pass are frequently covered in snow and ice.
Additionally, many popular tourist routes are remote, with limited access to help in case of breakdowns or accidents. You might find yourself in areas with spotty cellphone coverage, especially on scenic detours off State Highway 1.
That’s why winter driving safety isn’t just a good idea—it’s essential.
7 Essential Car Rental Driving Tips for Safe Winter Travel
1. Choose the Right Rental Car
When renting a car for winter travel in the South Island, opt for a vehicle with front- or all-wheel drive, and if possible, request one with snow chains and ABS brakes. This is especially important if you’re venturing into mountainous areas or planning to visit ski fields.
Reliable rental providers like RaD Car Hire New Zealand offer vehicles suitable for a wide range of winter conditions, with helpful staff who can advise you on what’s best for your route.
2. Check the Weather and Road Conditions Daily
Before setting off each day, check MetService NZ and Waka Kotahi NZTA websites for weather updates and road closures. Conditions can change rapidly, and a road that’s clear in the morning can be icy or snowed in by afternoon.
For additional seasonal safety advice, this guide on weather-ready driving is full of actionable tips—even though it focuses on spring, many suggestions apply year-round.
3. Drive Smoothly and Reduce Speed
Winter driving is all about smooth inputs—no sudden braking, acceleration, or sharp turns. Slow down when approaching corners or intersections, and increase your following distance from the car in front.
Slippery roads can extend stopping distances significantly. As a rule of thumb, keep at least four seconds between you and the vehicle ahead.
4. Use Your Lights, Even During the Day
Winter weather often brings overcast skies and fog, so always drive with your headlights on, even during daylight hours. This improves your visibility to other drivers and helps you see further ahead on the road.
If visibility gets especially poor, turn on your fog lights, if your car is equipped with them. Just remember to turn them off once conditions improve to avoid dazzling other drivers.
5. Be Prepared for Emergencies
A basic winter emergency kit can make a huge difference if you’re stuck or delayed. Include:
· A flashlight with spare batteries
· Warm clothing and blankets
· Non-perishable snacks and water
· A first-aid kit
· Phone charger/power bank
· Snow chains and a shovel
Knowing what to keep in your car for winter emergencies can give you peace of mind. If you’re unsure, ask your rental provider—RaD Car Hire staff are great at helping travellers prepare.
6. Don’t Rely on GPS Alone
While Google Maps is a fantastic tool, in the South Island’s more remote regions, cell reception is patchy at best. Always carry a physical map, or download an offline map of your route before you go.
Many tourists find themselves stranded because they took a “shortcut” recommended by their GPS through a mountain pass that was actually closed or impassable in winter.
7. Maintain Your Rental Car Properly
Even though you won’t be responsible for long-term vehicle maintenance, it’s still wise to monitor basic car health during your trip. Check the tyre pressure, windscreen washer levels, and fuel regularly—especially before heading into remote areas.
Your driving habits can also impact the car’s reliability. Practicing gentle braking and acceleration, for instance, can help maintain vehicle performance. See this guide on driving habits and vehicle longevity for useful tips.

By renting a well-suited car, checking conditions daily, and driving cautiously, you can fully enjoy the wonders of the South Island—without putting yourself or others at risk.
If you’re planning a visit this winter, companies like RaD Car Hire New Zealand and RaD Car Hire Australia offer well-equipped vehicles and knowledgeable staff to help you hit the road with confidence.
Frequently Asked Questions
What should I keep in my car for winter emergencies?
At a minimum, pack the following in your car:
· Blanket and warm clothes
· Water and high-energy snacks
· First-aid kit
· Flashlight and batteries
· Ice scraper and small shovel
· Snow chains (especially if driving through alpine passes)
· Fully charged mobile phone or a power bank
This kit can be invaluable if you’re delayed by road closures or become stranded.
Do I need winter tires or are all-season tires enough?
In most parts of New Zealand, all-season tyres are sufficient, especially if you drive cautiously and use snow chains when necessary. However, if you’re heading into areas with heavy snowfall like Queenstown or the Crown Range, ask your rental provider whether winter tyres are advisable.
Snow chains are more commonly used in NZ than winter tyres, and in some areas, you may be legally required to carry them.
How can I defog my windshield quickly?
To defog your windshield:
1. Turn on your car’s heater and direct the airflow to the windscreen.
2. Switch on the A/C to remove moisture from the air.
3. Open the windows slightly to balance the temperature.
4. Use the rear defroster for the back window.
If it fogs up regularly, keep a microfibre cloth or anti-fog spray handy for quick clearing.
