Backpacker's Guide - Winter Road Trip Prep: A Ski-Season Car Checklist

Winter is one of the best times to see New Zealand, and the snow and ski fields are a big reason many backpackers come. It's also when a road trip goes wrong fastest. Roads can close, ice can form overnight, and an old car battery that started fine in autumn can fail on a frosty morning. This checklist gets your car and your plans ready.

It builds on our road rules and hazards guide, which covers black ice, mountain passes and snow chains in more detail.

1. Plan Around the Weather

• Check MetService for rain, snow, wind and frost warnings before every long drive.
• Check the NZTA journey planner and road alerts for closures and chain requirements. Conditions can change within hours, so check the morning you travel, not the day before.
• Drive in the middle of the day where you can. NZTA suggests this because frost and ice are most likely to have melted, especially in shaded valleys and mountain passes where ice lingers.
• Allow extra time and avoid driving tired. A 100 km drive on a winter mountain road takes far longer than the map suggests.
• Have a plan B. If the pass closes, know where you'll stay and how you'll get around it.

2. Snow Chains

• On some alpine routes, road signs tell you where chains must be carried or fitted. On some roads, such as the Milford Road in winter, you need to carry chains when the signs say so, and driving past without them can lead to a fine.
• Make sure the chains fit your tyre size, learn how to put them on, and practise once in daylight on a dry, flat spot.
• Chains usually go on the driving wheels, so check your car's manual to see which ones.
• Ski field access roads often have their own chain requirements, so check the ski field's road report before you head up.

3. Get the Car Winter-Ready

• Battery: cold weather is hard on old batteries. If yours is more than a few years old, get it tested before you go. See our guide to jump-starting a car, and carry a jump pack or leads.
• Coolant: the mix needs to protect against freezing. Have a workshop check it if you're not sure.
• Tyres: the legal minimum tread is 1.5 mm, but you want much more than that on wet, icy roads. Check pressures and the spare, too. Our guide on checking oil, coolant and tyre pressure explains how.
• Wipers and washer fluid: fresh blades, and a washer fluid that won't freeze. See how to replace wiper blades.
• Lights and brakes: all lights working, and brakes that pull up evenly.
• Demister and heater: make sure they work, since a fogged windscreen is a hazard. Our guide on stopping windows fogging up helps.
• Fuel: keep the tank at least half full in winter, in case of delays or closures.

4. What to Carry

• Snow chains, and gloves for fitting them
• Ice scraper and de-icer (don't pour hot water on a frozen windscreen)
• Warm clothes, a blanket or sleeping bag, and a torch
• Water and snacks
• A phone charger or power bank, and offline maps
• A small shovel if you're going to alpine areas

5. If You're Sleeping in the Car

Cold nights need more than a big sleeping bag. Insulate from below with a mat, and keep some ventilation to control condensation, even though it feels backwards when it's freezing. Never run an unvented fuel-burning heater inside the car, because of the carbon monoxide risk. Our car-sleeping guide covers the rules and set-up.

6. Drive to the Conditions

• Slow down and leave much more following distance.
• Brake, steer and accelerate gently. Sudden inputs cause skids.
• Take extra care in shade, on bridges and early in the morning, where black ice hides.
• If you hit ice, stay calm, don't brake suddenly, hold the wheel steady and let the car slow down.

A Quick Pre-Trip Checklist

1. Weather and road conditions checked that morning.
2. Battery tested, coolant checked, tyres and spare checked.
3. Chains fitted once in practice.
4. Fuel above half, phone charged, offline maps downloaded.
5. Warm gear, water, torch, scraper and blanket in the car.

Check the Latest Before You Rely on This

We last checked this guide in September 2026. Road conditions, closures and chain requirements change by the hour and by the season, and the rules on which roads need chains can be updated. Before every winter drive, check:

• MetService, for weather, snow and frost warnings
• NZTA, for the journey planner, road closures and chain requirements
• The ski field's own website or road report, if you're heading to a ski area
