What Moving to New Zealand Taught Me About KiwiSaver

What Moving to New Zealand Taught Me About KiwiSaver

Author: Gonzalo Hernandez, Equity Analyst at Mint Asset Management.

After four years of holidays, I finally made the move to New Zealand in September last year. What I brought with me, besides an Aussie accent, was a 10-year career in funds management, for firms whose underlying clients spanned from mum and dads to some of Australia’s largest superannuation funds. One of the first things I noticed in everyday conversation was that New Zealanders don't talk about KiwiSaver the way Australians talk about “their super”.

In Australia, superannuation is a national obsession where people know and keep a close eye on their balances and argue about their respective super fund's performance at barbecues. They read their annual statements, and when the government tweaks the contribution rate or changes the tax treatment, it leads the evening news. Here, KiwiSaver often feels more like a direct debit people set up when they started their first job and haven't thought about since.

That gap in attitude is what struck me most, and perhaps it takes a foreigner to notice it. KiwiSaver is a genuine asset, it’s your asset, and one worth paying attention to.

Australia Started Where New Zealand Is Now
It is worth understanding where Australia began, because the starting point wasn't so different from New Zealand today.

When compulsory superannuation was introduced in Australia in 1992, the rate was 3%, exactly where KiwiSaver's default rate sat until this year. The scheme was voluntary in spirit, even if technically mandated. Employers resented it, and employees barely noticed it, whilst the financial industry hadn't yet figured out what to do with it.

Thirty years later, the picture is unrecognisable. Australian superannuation has accumulated over AU$4 trillion in assets. It is the fourth largest pool of pension savings in the world. It has materially reduced pressure on the government Age Pension. More importantly, it has changed what retirement looks like for ordinary Australians, not just wealthy ones.

That transformation didn't happen by accident overnight, it happened because of compounding time, rising contribution rates, and a slow cultural shift in how Australians thought about the money sitting in their super fund.

New Zealand is at the inflection point of that same journey, and Australia's experience at least offers some useful signposts.

The Numbers Tell a Confronting Story
Total funds under management reached NZ$123 billion with over 3.4 million members as of March 2025, according to the Financial Markets Authority, genuinely impressive figures for a country of five million people.

But reach and adequacy are different things, a December 2024 Te Ara Ahunga Ora Retirement Commission reported noted the average KiwiSaver balance across all members sits at $37,079 (+16% YoY). For those on the cusp of retirement aged 61 to 65 it is $69,104 (+16% YoY). To put that in context, Massey University's 2025 Retirement Expenditure Guidelines estimate that a couple in a main centre would need a further lump sum of just over $1 million to bridge the gap. Even a modest "no frills" retirement for a single homeowner requires meaningful savings well beyond what most members currently hold.

The gap between where most members are and where they need to be is not a rounding error. Too many New Zealanders are approaching retirement with KiwiSaver balances that will leave them relying almost entirely on the government pension, and that was never what the scheme was designed for. Australia faced the same reality in its early years. What changed it was not just policy, it was time, compounding, and people starting to recognise that this was their asset, not just a line on their pay slip.

The Power of Small Numbers Over Long Periods
The most important thing Australia's super system taught its members, and the thing I suspect is still under-appreciated in New Zealand, is how dramatically compounding transforms small, consistent contributions over a working life. A 35-year-old who increases their contribution by just 1% today could retire with tens of thousands of dollars more at 65. That is not a marginal improvement, it is simply the mathematics of time and consistency working in your favour.

This is why the government's decision to lift the default contribution rate from 3% to 3.5% in April 2026, and again to 4% in April 2028, matters more than it might appear. Half a percent of salary sounds trivial, but across millions of members, sustained over decades, it is anything but.

In Australia, each time the super guarantee rate lifted from 3% to eventually 12% in incremental steps over thirty years, the initial political noise was significant. Employers said it would kill hiring, whilst employees said they couldn't afford it. Both arguments proved largely unfounded once the adjustment bedded in. What remained was a structurally better retirement system.

The Conversation Australia Had That New Zealand Needs to Have
Beyond the policy mechanics, there is a cultural conversation that Australia had, messily over many years that New Zealand has yet to fully engage with, and it’s the one about financial literacy. Not in the abstract sense of understanding compound interest, but in the practical sense of knowing how to engage with the people managing your money. What are my returns after fees? How do I compare to similar funds? What is my manager actually doing with my money, and is it working?

In Australia, super members gradually learned to ask these questions, and it changed everything. Funds that couldn't answer clearly lost members to those that could, competition sharpened, and standards across the industry lifted as a result.

New Zealand isn't there yet, as most KiwiSaver members couldn't tell you their annual return, their fee as a percentage of their balance, or how their fund compares to its peers. That is not a criticism of Kiwis, it just reflects the fact that the scheme is still young, and the culture of engagement hasn't fully developed. But it will, and fund managers, me included, should be preparing for it.

The practical starting point is simpler than most people think, it’s as simple as logging in, checking your balance, looking at your annual return after fees, and asking whether your fund type matches your age and time horizon. Being in a conservative fund in your thirties is one of the most common and costly mistakes Australian’s have made in their scheme, and if you can't find clear answers on your provider's website, that itself tells you something.

None of this requires a financial degree, it simply requires the same shift in mindset that Australians made over time, from passive participant to informed owner. That shift, multiplied across millions of members, is what ultimately drives an industry to perform.

KiwiSaver's Bigger Opportunity
Australia's superannuation system didn't just create retirement wealth for its members, it built one of the most sophisticated funds management industries in the world. Australian managers, running Australian money, developed the capability to compete globally across every asset class. At the same time, the sheer scale of the super pool drew the world's largest investment firms to open Australian offices, employ local talent, and embed themselves in the domestic market. Capital attracted capability, and capability attracted more capital. That industry now manages money for institutions and sovereign wealth funds far beyond Australia's borders becoming an export industry in its own right.

New Zealand has the same ingredients, the talent and passion is here, I’ve felt it, and more internationals could be drawn here. KiwiSaver is still young, but as it scales it creates a genuine opportunity to build a funds management industry of real depth, one that manages global assets from Wellington and Auckland, creates high-value careers that keep New Zealanders at home, and attracts the kind of international expertise that lifts the whole financial sector. Kiwi money, grown by Kiwis, reinvested in New Zealand's economic future.

Australia built that over thirty years, and there is no reason New Zealand cannot do the same. KiwiSaver can become the foundation it gets built on.

Your Move
Every Australian I know of a certain age has a story about the moment they actually looked at their super balance and did the maths. For some it was motivating, for others confronting, and almost universally, it prompted action. New Zealand is approaching that moment, not just individually, but collectively. A maturing scheme, rising contribution rates, and a generation of members whose entire working lives have run alongside KiwiSaver means the stakes are becoming impossible to ignore.

The opportunity in front of New Zealand is genuinely exciting. A retirement savings scheme that provides for its members, an engaged population that holds its managers to account, and a funds management industry built on that foundation where it employs Kiwis, attracts talent, and manages money for the world from the bottom of the Pacific.

Australia built that, and I believe New Zealand has all the ingredients to do that next. But none of it happens without the first step, which is simply deciding that KiwiSaver is yours, not a government scheme, not a line on your pay slip, but your asset, your future, and worth your attention.
