Why You Can Earn $100k in New Zealand and Still Feel Broke

If you're earning $100,000+ in New Zealand and still checking your bank balance before payday, you're not alone A high income doesn't automatically create financial safety, and plenty of people on $100,000 or more feel just as stretched as they did on half that.

It's tempting to treat this as a discipline problem, like saying "YOU MUST SPEND LESS". But there's more to it than that. Rather, for many Kiwis it's about a handful of financial habits that feel completely normal, which is exactly why they're so easy to fall into and so hard to notice.

The gap between having a high income and building real wealth usually comes down to a few common traps, not bad luck or bad character.

In this post, I'll walk through each of them. When you can name them, they're a lot easier to avoid completely.

What is lifestyle inflation and why does it cancel out a pay rise?

Lifestyle inflation is the most common trap, and the most invisible one. Your income goes up, and your lifestyle quietly follows. The car gets upgraded, dinners out become more frequent, the holidays get a bit nicer, and you treat yourself more often. None of it feels excessive...It feels earned!

The problem is that spending rises automatically, but often saving and investing don't. So even though your income has risen, your financial position hasn't moved. This is how someone earning $70,000 and someone earning $120,000 can end up feeling exactly the same way about money, and still live paycheck to paycheck.

It also locks in higher fixed costs: bigger rent or mortgage repayments, higher car payments, more ongoing subscriptions and commitments. Once those are set, stepping back becomes genuinely hard. Posters on Reddit mention the value of continuing to live like a student, even after graduating, in order to keep lifetyle inflation down. It's not a bad approach, perhaps a bit extreme in my opinion, but it speaks to the value of keeping your costs in check and putting your excess capital to work.

Why does putting off investing cost you more than people realise?

Spending less is half the story...the other half is what you do with the savings, ideally through investing. It's easy to tell yourself you'll start once you earn more, once the market feels safer, or once you've "figured it out." If you're in the latter bucket, make sure to watch my YouTube back catalogue! In the meantime the money often just sits in a savings account earning less than inflation...sliding backwards!

The real cost isn't how much you put in, it's how long that money has to grow. Delay by five or ten years and you lose a big chunk of the benefit of compounding, which is where most long-term investment growth actually comes from.

Here's an illustrative example. Saving $500 a month from age 25 to 50 at an assumed average return of 8% a year would grow to roughly $438,000, from total contributions of about $150,000. Start five years later at 30 and save $750 a month instead, a 50% higher savings rate, and the total comes to roughly $411,000, still less than the earlier, smaller contribution. These figures are a hypothetical illustration assuming a constant annual return; actual investment returns vary and are never guaranteed.

Time in the market matters more than the size of the contribution, which means procrastination is one of the more expensive habits in personal finance, even though it doesn't feel like spending at all.

Is buying a house enough of an investment strategy on its own?

Property is often treated as the default path to wealth in New Zealand: buy a house, hold it long enough, and you'll be fine. That worked well for previous generations, but with property prices already high and many of the old tax advantages reduced (thanks government!), leaning on a house as your entire strategy isn't quite what it used to be. Our parents benefitted from (a) government actions to increase migration to New Zealand, (b) rising normality of double-income households, and (c) falling interest rates increasing mortgage serviceability. House prices are a function of affordability, and these three factors led to rampant inflation in housing costs.

A home you live in doesn't generate income or pay you anything while you own it. Unless you sell or borrow against it, its paper value doesn't change your monthly cash flow. It also concentrates your wealth in a single asset, in a single city, in a single country. New Zealand's average house prices have moved sideways or lower from 2022 through 2026, which is a reminder that "safe as houses" isn't guaranteed to hold in any given period.

This is how people end up asset rich but cash poor.

How does everyday debt quietly undercut a high income?

Car loans, BNPL, personal loans and credit cards have become a normal way to fund a lifestyle. On the surface, they make life easier. But every repayment is a claim on income you haven't earned yet, and interest, fees and charges add up if repayments slip.

Stack a few of these together and a real chunk of each pay cheque is already spoken for before it lands. High earners often qualify for more credit, so they take on more of it, not because they need to but because they can. New Mercedes anyone? Income rises, but so do the obligations attached to it, and the two can end up cancelling each other out.

Consumer debt isn't automatically a problem. Used carefully, for example only using a credit card when there's no surcharge, keeping the equivalent cash on hand to clear the balance in full, and checking the rewards are actually worth more than the annual fee, it can be a manageable tool. I personally do this with my Amex card, and I've got ~$560 in Air New Zealand Airpoints sitting and waiting for my next trip. The trap is using debt to fund a lifestyle you can't actually afford rather than as a deliberate, fully repaid choice.

Why does automating your savings make such a big difference?

Without a system, saving becomes whatever's left over after everything else is paid for, and "whatever's left over" is inconsistent by nature. Some months it happens, other months it doesn't, and that gap compounds over years. If you're a bit lazy like me with admin, butting your finances on auto-pilot means you're doing the right thing, even without thinking about it.

Paying yourself first flips the order: a portion of income is redirected into savings or investment accounts as soon as it arrives, then invested automatically from there. No monthly decision, no willpower required, just consistency. Building wealth isn't about making a perfect decision every month, it's about removing the need to decide at all, so the easy option is also the one that builds your position over time.

Does someone else's financial success come at your expense?

The final trap is thinking about money in zero-sum terms: if someone else is doing well, they must have taken something from you. It shows up as "must be nice," "they just got lucky," or "they've got something I don't." New Zealand has too much of this, and any real business owner knows that collaboration is what grows the pie and allows everyone to get ahead together. We compete in a global market, there's a reason why Fonterra and Zespri were created to band all of our farmers and growers together to negotiate better terms on the global stage.

Wealth isn't a fixed pie that everyone is fighting over. It's created, and someone else winning doesn't mean you're losing. Believing otherwise tends to breed resentment instead of curiosity, and it keeps people on the sidelines, avoiding opportunities and assuming the system is rigged against them. People who build wealth tend to look at what's working for someone else and ask how they could do something similar, rather than writing it off as luck. Works especially well for YouTube: copy what works overseas or in another niche, and replicate that for your own audience.

Frequently Asked Questions

Does earning more money guarantee you'll build wealth?

No. A higher income only builds wealth if saving and investing rise along with it. Without that, spending tends to expand to match the new income, a pattern known as lifestyle inflation.

Is it better to invest in property or shares in New Zealand?

Both come with different trade-offs rather than one being universally better. An owner-occupied home doesn't generate income and concentrates wealth in one asset, while shares can offer income, growth and easier diversification across countries and industries.

How much money do I need to start investing?

There's no minimum figure that matters more than simply starting. Time in the market has a bigger effect on long-term outcomes than the size of each contribution, so delaying by even a few years can meaningfully reduce the end result.
