Renting a Car in New Zealand: Licence, Excess and Unsealed Roads — What to Check Before You Sign

A valid French driving licence lets you drive in New Zealand for up to 12 months as a visitor — but on one condition too often overlooked: the document must be written in English or come with an approved translation, otherwise rental companies and police require an International Driving Permit (IDP). A French licence, written in French, falls squarely into that case: without an IDP or a translation certified by a service recognised by New Zealand’s transport agency (NZTA / Waka Kotahi) or by a diplomatic mission, the rental counter is entitled to refuse you the keys.

Another change to know for 2026: since 3 March 2026, the French International Driving Permit is no longer free. The application, now handled exclusively online via the ANTS portal, costs €7.25 and takes 2 to 4 weeks to be issued — a delay worth planning for before departure, since the document stays valid for up to 3 years. Always carry both documents together: only the original French licence is the legal document, the IDP being nothing more than an official translation that never stands on its own.

The advertised daily rate — often €25 to €45 for a city car in the shoulder season — hides a damage excess that climbs fast depending on the rental company and category chosen. Here are 2026 ballpark figures, based on an indicative rate of 1 NZD ≈ €0.51.

The excess-reduction option sold at the counter typically costs 25 to 35 NZD a day (€13-18). A third-party excess insurance bought online before departure — an independent excess-buyback policy — often costs two to three times less for comparable cover, as long as you check it covers the same exclusions as the rental company’s own contract, unsealed roads included.

Unlike a zero-excess option, which protects against parking-lot dents, no add-on buys back damage suffered on a permanently unsealed road: almost every New Zealand rental contract flatly excludes their use, regardless of the insurance level purchased. Iconic tracks such as Skippers Canyon Road near Queenstown, Ball Hut Road toward Tasman Glacier, or several back roads in the Catlins appear explicitly on rental companies’ blacklists — a crash or a puncture there is entirely the driver’s liability.

A second, sneakier trap: on a road that’s normally sealed but temporarily covered in loose chip (roadworks, wear), the contract technically stays valid, but chip damage — a cracked windscreen, paint chips, cut tyres — is very often excluded from the base cover and needs a dedicated ‘glass and tyres’ add-on. Before committing to a track shown as a gravel road on a map or GPS, it’s worth confirming in writing with the rental company that it’s still allowed.

Most rental companies set the minimum age at 21, with a systematic young-driver surcharge under 25 — often 15 to 25 NZD extra per day — and sometimes restricted access to 4x4 or premium categories below that age. Another near-universal condition: a licence held for at least one year, with proof required. A recently issued licence can be enough to get the rental refused, regardless of the driver’s age.

New Zealand popularised a unique scheme: rental vehicle relocation, where companies offer slashed rates — sometimes 1 NZD a day — to travellers willing to drive a van or car from one city to another to rebalance their fleet. A study by Yunzhen Zhang (University of Otago), published in 2024 in the journal Current Issues in Tourism, describes the practice as far more than cut-price transport: travellers who use it often experience it as a road trip in its own right, shaped by its own constraints — a fixed route and date window, sometimes a capped mileage (study available here: www.tandfonline.com/doi/full/10.1080/13683500.2024.2409858).

These deals remain full rental contracts: excess, licence rules and unsealed-road exclusions all apply exactly the same way. The saving is on the vehicle’s daily rate, not the extras — insurance and fuel stay on you, and strictly sticking to the imposed deadline and route is what keeps the promotional rate valid.

A University of Otago study led by Neil Carr and Ismail Shaheer, surveying 226 international visitors in Queenstown, found a very partial grasp of New Zealand road rules among foreign drivers: only 7 of the 226 participants, from 34 countries, correctly answered a test drawn from the actual local theory exam questions (study reported by the University of Otago, also searchable on Google Scholar: scholar.google.com/scholar?q=Shaheer+Carr+self-drive+tourists+New+Zealand+road+rules).

That finding matches what rental companies see on the ground: single-lane bridges with a flashing-arrow priority system, roundabouts that are unfamiliar to drivers from some countries, and the reflex to drift back to the right after a stop or a fuel break are the most common traps of the first few days driving on the left. No insurance replaces a proper briefing at the rental counter and extra caution over the first 200 km.

The ‘Self-Drive New Zealand’ guide breaks down, vehicle by vehicle, the excess actually charged by major brands and local rental companies, an up-to-date list of roads excluded from contracts, and a booking calendar to secure a van on the best terms before the southern-hemisphere peak season.
