The $3 Litre Wake-Up Call: New Zealand's EV Hesitancy Was Never Really About the Cars

When petrol hit $3 a litre in New Zealand in March 2026, the phone lines at EV dealerships lit up. One Christchurch dealer reported sales jumping 50% in a fortnight. An Auckland dealership saw overnight enquiries double. The government announced $52.7 million in interest-free loans for 2,574 new EV chargers. Suddenly, a lot of people were rethinking what they drive.

For many of these people, there was no good reason to wait this long.

Not everyone. There are households where the budget genuinely didn't stretch, where the charging infrastructure didn't reach, where the use case truly didn't fit. I'm not talking about them. I'm talking about the broad middle of New Zealand, i.e. people with driveways, steady incomes, and daily commutes well within EV range who could have made the switch two or three years ago and chose not to. They never actually ran the numbers. That's what I keep coming back to.

New Zealand's fuel vulnerability, laid bare

The Middle East conflict that sent crude oil past US$100 a barrel and effectively shut down the Strait of Hormuz exposed a vulnerability most of us preferred to ignore. New Zealand imports every drop of its refined fuel, mostly from refineries in South Korea and Singapore that depend on crude shipped through those contested waters. Since Marsden Point closed in 2022, we have no domestic refining capacity and roughly 50 days of supply on hand.

Meanwhile, more than 80% of New Zealand's electricity comes from renewable sources. In Q4 2025, that figure hit a record 96.4%. The grid doesn't care what's happening in the Strait of Hormuz. If you charge an EV at home overnight, you're paying roughly $4.50 per 100km in electricity. Add Road User Charges and the real cost is closer to $12 per 100km. With petrol above $3 a litre, a typical petrol car costs over $30 per 100km. Even after RUC, the EV is less than half the price.

What seven years of EV ownership actually looks like

Our household has run two EVs since 2019. Between them we've covered around 300,000 kilometres, all fully electric. We charge overnight, partly from solar, and our entire house runs on electricity, i.e. heating, cooking, hot water, two cars. All of it for under $400 a month in winter (and about half that in summer). A comparable household running petrol vehicles might spend that on fuel alone. Over seven years the running cost difference adds up to tens of thousands of dollars. Our actual power bills tell that story clearly enough.

We went backwards while the world moved forward

So why didn't more people do this? Used EVs dropped below $15,000, the charging network expanded, and battery technology improved across the board. Yet New Zealand's EV market share actually fell after the government removed the Clean Car Discount, from around one in four new cars to roughly one in nine.

For context, comparing plug-in vehicle share (BEVs and PHEVs combined) across markets:

New Zealand sits at around 11%, with pure battery electrics at just 5.6%
Australia is at over 13% and climbing fast, with 38% year on year growth
The global average is one in four new cars sold

By any measure, we went backwards.

The psychology behind the hesitation

I think I know what happened. And I say this with real empathy because these are human tendencies we all share. I'm not immune to them.

Status quo bias. Behavioural economists Samuelson and Zeckhauser defined this in 1988: our preference for keeping things as they are, even when the evidence says we'd be better off changing. It gets stronger when decisions feel complex and the stakes feel high. Buying a car ticks those boxes for most people. So instead of evaluating the options fresh, you default to what you know. You buy another petrol car because that's what you've always done.

Loss aversion. From Kahneman and Tversky's prospect theory: losses feel roughly twice as painful as equivalent gains feel good. When you consider switching to an EV, your brain doesn't weigh up "$12 per 100km vs $30 per 100km in petrol." It fixates on what you might lose. What if the battery degrades? What if you can't find a charger on the road to Napier? What if the resale value tanks? The potential downsides loom large while the daily savings barely register.

Tradition barriers. Researchers describe this as the psychological resistance that kicks in when an innovation challenges your identity or habits. Cars aren't just transport. They're wrapped up in how you see yourself, what your mates drive, and what feels normal in your social circle. If nobody in your world drives an EV, choosing one feels like making a statement. Plenty of people would simply prefer to avoid that.

These biases compound each other. In practice, the pattern looks something like this:

You form an opinion about EVs in 2020 or 2021 based on the prices and infrastructure at the time
That opinion gets filed as "not for me" and you stop actively looking
You picture the one long road trip instead of 350 ordinary commuting days
You compare sticker prices without running the full cost of ownership
You mistake unfamiliarity for inconvenience
Every year you don't revisit that decision, the gap between your assumptions and reality grows wider

The market changed, the prices dropped, and the charging network expanded. But your mental model stayed frozen somewhere around 2021.

The real cost of waiting

I'm not pointing fingers. But this kind of cognitive inertia costs households thousands of dollars a year. And it took a war and $3 petrol to finally shake it loose.

For those of us already driving electric, this crisis changed nothing about our daily routine. We just plugged in as usual.

If you've been on the fence, I'd genuinely encourage you to do one thing: run the numbers for your actual situation. Your commute, your electricity rates, your current fuel spend. You might surprise yourself. And if you want to chat about what seven years of real-world EV ownership looks like, I'm happy to share what I've learned.
