As we move towards a world of zero emissions, electric vehicles (EVs) are becoming a popular alternative to cars, which have an internal combustion engine. In New Zealand, there are 77,670 battery electric vehicles (BEVs) in 2024, which is up from 4483 or 16x from 2017.
However, owning an EV isn’t just about being environmentally friendly—it comes with practical considerations like model selection, charging infrastructure, servicing, and, of course, car insurance.
In this post, we’ll explore how insurance for EVs compares to gas vehicles. Factors like repair costs, specialised parts, and advanced technology can all impact premiums. So, does going green mean paying more for car insurance? And how can Quashed help? Let’s take a look.
The EV versus Gas showdown: real insurance comparisons
Using data from the NZ Electric Vehicle Database and Quashed’s Market Scan (which is free to access), we compared three of the most popular EVs with similar petrol and hybrid models. To ensure fairness, we used the same sum insured, excess, and a driver's profile—a 40-year-old from West Auckland. The results below are only for comprehensive car insurance only.
Case study 1: Tesla Model Y v Subaru Forester V Toyota RAV4 Hybrid
In this case study, we can see the average insurance cost for the Tesla Model Y ($2,800) is approximately 40% higher than the insurance premium for the petrol Subaru Forester 2.5i, ($2,003) and about 29% higher than the Toyota RAV4 Hybrid ($2,172).
So, why the difference? The evidence from around the globe points to several key factors. Tesla vehicles are equipped with advanced technologies, like electric powertrains, which require specialised tools and technicians, often resulting in higher repair costs. Additionally, Tesla, as a newer vehicle manufacturer, lacks the large-scale production and distribution networks that long-established brands like Toyota and Subaru have.
Case study 2: Nissan Leaf v Mazda 3 v Toyota Corolla
In this comparison, the Nissan Leaf stands out with the highest insurance costs, ranging from $1,442 to $2,078, with an average of $1,813. This higher premium reflects the repair complexities common to EVs, particularly the costly battery systems.
Meanwhile, the Toyota Corolla Hybrid offers a solid middle ground, being 15% cheaper to insure than the Leaf. It blends the fuel efficiency of electric technology with the lower insurance costs typical of hybrids, providing a balanced option for cost-conscious drivers.
Although the Corolla Hybrid also outpaces the Mazda 3 in terms of affordability, with a 3.9% reduction in insurance costs, the difference is smaller but still notable, making both the Mazda and the Corolla attractive choices depending on one's preference for hybrid efficiency or traditional petrol.
Case study 3: BYD Atto 3 v Mazda Cx-5 V Hyundai Tucson
In this case study, the insurance costs for the BYD Atto 3, Mazda CX-5, and Hyundai Tucson Hybrid reveal key insights beyond just technology differences.
The BYD Atto 3, with the highest average cost at $2,599, reflects more than just expensive batteries. Higher premiums stem from specialised repair needs and limited parts availability, making it 7.2% more costly to insure than the Mazda CX-5 and 10.4% more than the Hyundai Tucson Hybrid.
The Mazda CX-5, with an average cost of $2,423, benefits from simpler repairs and a well-established service network. This stability keeps its insurance costs predictable, though still 3.0% higher than the Tucson Hybrid.
The Hyundai Tucson Hybrid, with the lowest average cost of $2,354, strikes a balance between fuel efficiency and lower repair costs. Hybrids, by combining petrol and electric systems, keep premiums down while offering modern technology.
In short, the BYD Atto 3 may be cutting-edge but comes with higher insurance costs due to complex repairs. The Hyundai Tucson Hybrid, meanwhile, offers the best balance of technology and affordability for cost-conscious drivers.
What does this all mean for kiwi drivers?
For Kiwi drivers, the choice between electric, petrol, or hybrid vehicles isn’t just about fuel efficiency, CO2 emissions, and maintenance costs—it also impacts your insurance premiums.
If you’re considering an electric vehicle like the BYD Atto 3, insurance costs tend to be higher due to expensive repairs and specialised parts, particularly for the battery.
In contrast, petrol vehicles, such as the Mazda CX-5, often provide more predictable and affordable insurance premiums, thanks to simpler repairs and a well-established service network. For drivers prioritising stability in insurance costs, petrol cars remain a reliable choice.
In a previous blog on New Zealand’s most popular vehicles and their insurance costs, we advised Kiwi drivers to consider insurance costs before choosing a car. This advice is especially relevant for car buyers interested in EVs, given their insurance rates can be higher than those for petrol or diesel cars.

What is the future of electric car insurance?
The automotive industry is changing fast. With the growth of EVs, new safety technologies, and self-driving features, vehicle insurance will also change a lot. As we use technology in our cars, insurance needs to keep up with these changes.
New trends like usage-based insurance, telematics, and risk assessments based on data will likely change vehicle insurance in the future. Let's look at a couple of these trends and predictions more closely.
EV popularity and its impact on insurance
With EVs becoming more common, we can expect more changes in the insurance world to match their new risks and advantages.
In the future, car insurance may involve closer work between car makers, tech providers, and insurance companies. This teamwork will help create new solutions for EV owners.
Tech improvements and better charging options are important for speeding up the use of EVs. These factors will also shape the future of car insurance.

Advances in safety technology and autonomous driving features
Advances in safety technology, especially in self-driving features, can change car insurance forever. Companies like Tesla and BMW are always working to improve self-driving abilities. Their goal is to make roads safer and reduce mistakes made by drivers.
As these self-driving technologies get better, insurance companies may need to change the way they look at risk and set prices. Switching to self-driving cars will require a major rethink of who is responsible when accidents happen. Insurers will create new ways to price and provide coverage.
Though fully self-driving cars are still some years away, features that help drivers today are already impacting insurance prices. Cars with systems like adaptive cruise control, lane-keeping assist, and automatic emergency braking show they have a lower risk of accidents. This could lead to cheaper insurance rates for these vehicles in the future.
