South Island Road Trip Costs: Fuel, Tolls & Budget

Quick answer: what does the driving cost?

The main driving cost on a South Island road trip is fuel — how much depends on your route, your vehicle’s economy, and current pump prices. There are no toll roads on the South Island, so you can plan without factoring tolls in. Budget mainly for fuel (or EV charging), plus the usual accommodation, food and activities. Fuel prices change, so treat the figures below as estimates and check current prices before you go.

Fuel cost by popular route

A rough fuel estimate is: distance ÷ 100 × your car’s litres-per-100km × the current price per litre. As a guide, the classic legs are Christchurch to Queenstown (~550 km), Christchurch to Lake Tekapo (~227 km), and Queenstown to Wanaka (~70 km). Multiply the distance by your vehicle’s economy and the current fuel price to estimate each leg. A full Christchurch-loop road trip covers well over 1,500 km, so fuel is the cost worth planning around.

• ✓Estimate = km ÷ 100 × L/100km × price per litre
• ✓Christchurch → Queenstown ≈ 550 km
• ✓Full South Island loop ≈ 1,500 km+
• ✓Check current pump prices — they vary by town and over time

Are there toll roads in New Zealand?

New Zealand has only a small number of toll roads, and all of them are in the North Island. There are no toll roads on the South Island, so a South Island road trip has no tolls to budget for or pay online. You can plan your route purely around distance, time and stops.

Driving an EV instead

If you’re touring in an electric car, “fuel” becomes charging. Public fast-charging is widely available on the main South Island routes, and charging is typically cheaper per kilometre than petrol or diesel, especially if you can top up overnight at your accommodation. Plan longer legs (like the West Coast and the passes) around charger locations. See our EV road trip guide for the charging network and range-friendly routes.

Sample budget and money-saving tips

Beyond fuel, budget for accommodation, food, and activities — these usually outweigh the driving cost. To keep the driving budget down: choose an economical or electric vehicle, drive smoothly to save fuel, fill up in larger towns where fuel is often cheaper, and group your activities by region to avoid backtracking. Booking your vehicle and accommodation ahead in peak season also avoids last-minute premiums.

• ✓Pick an economical or EV vehicle for long loops
• ✓Fuel up in larger towns; remote stops cost more
• ✓Group activities by region to cut backtracking
• ✓Book ahead in peak season to avoid premiums
