Electric vehicles compared to petrols & hybrids: do they cost more to insure?

The EV Versus Petrol Showdown: Real Insurance Comparisons

Using live pricing data from the Quashed Market Scan (free to use), we compared three of the most popular EVs with similar petrol and hybrid models. To keep the comparison fair, we standardised the driver profile—a 30-year-old from Auckland—with a $500 excess, no accident history, and a full NZ licence with 5+ years of experience. All prices shown are for comprehensive car insurance, paid monthly.

To ensure a true apples-to-apples comparison, we’ve only included insurers that returned a quote for every vehicle in each case study. This means you’re comparing the same set of insurers across the board.

Important: The prices shown below are based on a specific driver profile and were retrieved at a single point in time. Your individual results will vary based on your age, gender, location, driving history, claims history, licence type, vehicle value, excess level, and the level of cover you choose.

For context, the average cost of comprehensive car insurance in New Zealand is $1,298 per year ($108/month) as of Q4 2025, according to the Quashed Insurance Index published in February 2026.

Case Study 1: Tesla Model Y vs Subaru Forester vs Toyota RAV4 Hybrid

The Tesla Model Y’s average annual insurance cost ($3,261) is approximately 38% higher than the petrol Subaru Forester 2.5i ($2,370) and about 29% higher than the Toyota RAV4 Hybrid ($2,524).

So, why the difference? The evidence from around the globe points to several key factors. Tesla vehicles are equipped with advanced technologies, including electric powertrains, which require specialised tools and technicians—often resulting in higher repair costs. Tesla, as a relatively newer vehicle manufacturer, also lacks the large-scale production and distribution networks of established brands like Toyota and Subaru. With fewer Tesla-certified repairers in New Zealand, wait times for parts and repairs can be longer, and insurers price that additional risk into your premium.

Interestingly, the RAV4 Hybrid sits in the middle. It blends the fuel efficiency benefits of electric technology with the well-established Toyota service network, keeping insurance costs more predictable than a full EV.

Case Study 2: Nissan Leaf vs Mazda 3 vs Toyota Corolla Hybrid

The Nissan Leaf has the highest average insurance cost in this group at $1,945 per year—roughly 6% more than the Mazda 3 ($1,828) and 11% more than the Toyota Corolla Hybrid ($1,748).

This premium gap reflects the repair complexities common to EVs, particularly the costly battery systems. Despite its lower price tag, the Leaf’s specialised EV components push insurance costs higher than both alternatives.

The Toyota Corolla Hybrid offers the most affordable insurance in this group. It blends the fuel efficiency of electric technology with the lower repair costs typical of hybrids and benefits from Toyota’s extensive service network in New Zealand. The Mazda 3 sits close behind, offering strong value for drivers who prefer a traditional petrol vehicle.

Case Study 3: BYD Atto 3 vs Mazda CX-5 vs Hyundai Tucson

The BYD Atto 3, with the highest average annual cost at $2,486, is approximately 18% more expensive to insure than the Mazda CX-5 ($2,105) and about 14% more than the Hyundai Tucson ($2,181).

The BYD Atto 3’s higher premiums reflect more than just its EV technology. As a relatively new brand in New Zealand, BYD faces the same challenges as Tesla: limited local repair networks, specialised parts that may need to be imported, and fewer technicians trained to work on the vehicles. These factors all contribute to higher insurer risk assessments.

The Mazda CX-5 benefits from simpler petrol-engine repairs and a well-established service network across New Zealand, keeping its insurance costs the most predictable of the three. The Hyundai Tucson sits close behind—its growing market presence and competitive service network help keep premiums manageable.

What Does This Mean for Kiwi Drivers?

Across all three case studies, a consistent pattern emerges: EVs cost more to insure than their petrol or hybrid equivalents. The premium gap ranges from around 6% to nearly 38%, depending on the vehicle.

For Kiwi drivers, the choice between electric, petrol, or hybrid isn’t just about fuel efficiency, CO₂ emissions, and running costs—it also has a meaningful impact on your insurance premiums. Here’s a summary of the key takeaways:

EVs carry higher repair costs. Advanced components like battery packs, electric drivetrains, and sensor arrays require specialist tools and trained technicians. In New Zealand, where the number of certified EV repairers is still growing, this translates to longer wait times and higher labour costs—which insurers factor into premiums.

Newer brands face steeper premiums. Both Tesla and BYD—as relatively recent entrants to the NZ market—lack the deep service networks of established manufacturers like Toyota, Mazda, and Subaru. Limited parts availability and fewer trained repairers increase the risk for insurers.

Hybrids offer a middle ground. Vehicles like the Toyota RAV4 Hybrid and Corolla Hybrid blend fuel efficiency with the lower repair costs of conventional drivetrains. Their insurance premiums generally sit between full EVs and petrol vehicles, making them an attractive option for cost-conscious drivers who still want to reduce their environmental footprint and save on fuel.

Don’t Forget: EVs Now Cost More to Register, Too

Insurance isn’t the only area where EV owners face higher costs. As of 1 July 2025, electric vehicles no longer receive a discounted ACC levy and now pay the same rate as diesel vehicles. Combined with the January 2026 rego fee increases, the annual licensing cost for an EV is now $241.59 for 12 months—roughly 40% more than a petrol vehicle ($172.97). For a full breakdown, read our guide to car registration and licensing costs in NZ.

What Is the Future of Electric Car Insurance?

The automotive industry is evolving rapidly. With the rise of EVs, advanced safety technologies, and autonomous driving features, vehicle insurance is set to undergo significant changes. As technology integrates further into our vehicles, insurance will need to adapt to meet new demands.

EV Popularity and Its Impact on Insurance

With EVs becoming more common—New Zealand’s registered EV fleet has grown roughly 20-fold since 2017—we can expect the insurance market to adapt. As repair networks expand, more technicians are trained, and parts become more readily available, the cost gap between insuring an EV and a petrol vehicle should narrow over time.

We’re already seeing this with the Nissan Leaf, which has been on New Zealand roads long enough for repairers to develop expertise and for a healthy used-parts market to emerge. Newer brands like BYD and Tesla may follow a similar trajectory as their presence in the NZ market matures.

Advances in Safety Technology and Autonomous Driving

Advancements in safety technology, especially autonomous driving features, could reshape car insurance fundamentally. Features like adaptive cruise control, lane-keeping assist, and automatic emergency braking are already demonstrating lower accident rates—and some insurers are beginning to factor these into pricing.

As self-driving technologies improve, insurers may need to rethink how they assess risk entirely. The shift from driver error to system reliability as the primary risk factor will require new pricing models and coverage structures.

Usage-Based Insurance: An Emerging Trend

Usage-based insurance (UBI)—where your premium is partly determined by how much and how safely you drive—is a growing trend globally and is starting to gain traction in New Zealand. AA Insurance already offers its Smartdriver programme, which tracks driving behaviour through a smartphone app and can provide discounts of up to 30% for safe drivers.

FAQs

Do EVs really cost more to insure than petrol or hybrid cars?

Yes, in most cases. Our data consistently shows that EVs carry higher insurance premiums than comparable petrol and hybrid vehicles. The gap varies—in our comparisons, EV insurance costs were between 6% and 38% higher. The main drivers are higher repair costs, specialised parts, and a limited number of certified repairers in New Zealand. Hybrids, on the other hand, tend to sit closer to petrol vehicles in terms of insurance cost, as they still use conventional drivetrains alongside their electric components. Shopping around is the most effective way to find a competitive rate for any vehicle type.

Why are EV repairs more expensive?

EVs include advanced technology and high-cost components—particularly battery systems—that significantly increase repair costs. Even relatively minor accidents can require specialist equipment and trained technicians. Parts often need to be imported, and there are fewer qualified repairers in New Zealand compared to those servicing petrol vehicles. Insurers factor all of these risks into premiums.

Does my EV battery need special insurance?

Most comprehensive car insurance policies in New Zealand include coverage for your EV’s battery if it’s damaged in an accident, fire, or theft. However, gradual battery degradation (loss of capacity over time) is generally not covered—this is treated the same way as normal wear and tear on a petrol engine. If you lease your battery separately, check whether your policy covers it. Always read the fine print.

Can I get Mechanical Breakdown Insurance (MBI) for an EV?

Yes. Several MBI providers in New Zealand now cover electric and hybrid vehicles, including Autosure (which offers an EV-specific package), Provident Insurance, and Protecta (Assurant). MBI covers sudden and unforeseen mechanical or electrical failures—which is separate from your comprehensive car insurance. Given the high cost of EV-specific repairs (particularly battery and drivetrain components), MBI can be especially valuable for EV owners, particularly once the manufacturer’s warranty has expired. For more detail, read our guide on Mechanical Breakdown Insurance vs Comprehensive Car Insurance.

Does charging my EV at home impact my home insurance?

It can. Some insurers ask about EV chargers, as improper installation may pose a fire risk. If you’re installing a home charger, ensure it’s done by a qualified electrician and inform your insurer. Being upfront helps avoid issues if you need to make a claim.

How can I lower my car insurance costs?

Whether you drive an EV, hybrid, or petrol car, the same core strategies apply: compare quotes from multiple insurers (the biggest single lever), opt for a higher excess, adjust your sum insured to reflect current market value, park in a secure location, and maintain a clean driving record. Using the Quashed Market Scan is the fastest way to compare—Quashed users found a cheaper policy 80% of the time in Q4 2025, saving an average of $367 per year. For more tips, read our guide on proven ways to lower your car insurance premium.

Does third-party insurance cover EVs differently?

No—third-party policies work the same for EVs as they do for petrol cars. However, given the high cost of EV repairs, comprehensive cover is generally the smarter option for EV owners. A minor accident that might cost $2,000 to fix on a petrol car could easily cost $5,000 or more on an EV due to specialised components. For a full breakdown of the cover types, read our comprehensive vs third party guide.

Are there insurers in NZ that specialise in EVs?

No insurer in New Zealand exclusively specialises in EVs. Most comprehensive car insurance policies will cover your EV's battery if it's damaged in an accident, fire, or theft — but this is standard comprehensive cover, not a dedicated EV benefit. Some insurers go further: AMI covers your charger and charging cable as an accessory, and Tesla's InsureMyTesla product (underwritten by Vero) includes cover for home charging equipment. Benefits vary between providers, so comparing policies side by side is the best way to see what's included — Quashed's Market Scan makes this easy.

Will EV insurance get cheaper over time?

It’s likely. As EV adoption increases, repair networks expand, and parts become more readily available, the cost gap should narrow. We’re already seeing more competitive premiums for well-established models like the Nissan Leaf. However, the pace of change depends on claims data, repair costs, and how quickly the market adapts. In the meantime, comparing quotes regularly is the best way to ensure you’re not overpaying.
