Your first year as a doctor is huge. You’re finally doing the thing—working as an essential part of the team, taking on real responsibilities, and actually helping people. It’s exciting, overwhelming, and a little surreal.
You’re also earning proper money for the first time. After some well-deserved splurges, you might start wondering:
“What am I actually supposed to do to be smart with money?”
This stuff isn’t taught in med school. Most people either figure it out the hard way or stumble through years of expensive mistakes.
So let me be your financial big sister. Here are the top 5 things I told my little sister when she started as a house officer—the things I wish someone had told me.
1. Make the Most of Your Leave—and Travel While You Can
Yes, you can travel later in life. But now—before mortgages, partnerships, and toddlers—is the golden window.
Hostels, overnight buses, and 2am flights are just part of the adventure when you’re young and free. I’ve never met a single doctor who regretted travelling or taking time out to pursue something they loved.
Life is for living too. You don’t need to delay joy just because you’ve entered “professional” life.
The money will be there later. These years? They won’t.
2. If You Can’t Pay for It in Cash, You Can’t Afford It
Credit cards and buy-now-pay-later services are like smoking: tempting, instantly gratifying, and deceptively dangerous.
Want a holiday? Save for it. Want a car upgrade? Save for it.
Start building the habit now of saving first, spending later. Your future self will thank you for not normalizing debt.
The easiest way? Automate it. Set up a transfer on payday so your savings happen before you even see the money. What you don’t see, you won’t spend.
3. Sort Your KiwiSaver Out
Don’t let fear of the unknown make you put KiwiSaver in the too-hard basket.
KiwiSaver is one of the most powerful wealth-building tools you have as a Kiwi doctor. But most people set it up once and never look at it again—which means they’re likely leaving money on the table.
A few small tweaks can help your balance grow faster:
- High fees (above 0.5%) quietly eat away at your returns — over your career, this could cost you hundreds of thousands
- Being in a fund that’s too conservative for your life stage is like driving with the handbrake on — if you’re decades from retirement, you can afford more growth
- Missing your full employer match means leaving free money on the table — Te Whatu Ora will match up to 6%! Are you contributing enough to get it all?
- Not maximizing the government top-up — are you contributing at least $1,042.86 per year to get the full $521.43 member tax credit?
You don’t need to become a KiwiSaver expert. You just need to spend 20 minutes getting it right.

4. Investing Isn’t Hard
Investing sounds scary because no one teaches us this stuff. But the truth? The best investment strategy isn’t complicated—it’s backed by decades of research.
Evidence-based investing means following what actually works, not chasing hot tips or trying to beat the market.
Here’s what the evidence tells us:
- Invest regularly — consistent contributions beat trying to time the market
- Keep fees low — aim for total fees under 0.5%. High fees are one of the biggest predictors of poor returns
- Diversify broadly — spread your risk across thousands of companies through low-cost index funds
- Stay invested for the long haul — time in the market beats timing the market, every time
- Ignore the noise — market ups and downs are normal. Stick to your plan
You don’t need to pick individual stocks. You don’t need to watch the market daily. You don’t need to get fancy.
Just follow the principles that have been proven to work—and let compound growth do its thing.
Even $50 a week invested consistently in a low-fee, diversified fund will grow into something significant over your career.
5. Figure Out What Self-Care Really Means for You
None of the financial stuff matters if you’re too burned out to earn—or enjoy—your life.
Medicine is tough. The hours, the pressure, the emotional toll—it all adds up. That’s why self-care isn’t a luxury. It’s essential.
And it’s not about face masks and bubble baths (though if that works for you, great). It’s about what genuinely helps you feel rested and recharged.
Exercise? Sleep? Time in nature? Saying no to extra shifts when you’re running on empty?
Make it a non-negotiable. Protect your energy like you protect your patients.
Your future self will thank you.
Final Thoughts
You don’t need to have it all figured out. But starting with just one of these will set you up far better than most.
And remember: I’m cheering you on.
You’ve worked so hard to get here. Now let’s make sure your money works hard for you too—so you have choices, not just a salary.
