The Retirement Savings Gap for New Zealand Women

Picture two colleagues, both starting their careers at the same company on the same day. Fast-forward 35 years to retirement, and statistically, if one is a woman and one is a man, there will likely be a substantial difference in their KiwiSaver balances. Not because one saved more diligently or made smarter investment choices, but because of factors largely outside their individual control.

This is the retirement savings gap for women in New Zealand, and it's real, measurable, and affecting your future financial security right now. According to research from Sorted, women tend to retire with significantly lower KiwiSaver balances than men, a pattern that mirrors international trends where women accumulate 20-30% less retirement savings over their working lives.

If you've ever felt behind in your retirement planning, or wondered why building your nest egg seems harder than it should be, you're not imagining things. And more importantly, you're not alone.

Let's clear up a common misconception right away: women aren't worse at managing money or less interested in retirement planning. The retirement savings gap exists because of structural factors that affect women's earning and saving patterns throughout their working lives. Understanding these factors isn't about assigning blame; it's about recognizing the landscape so you can navigate it more effectively.

According to Stats NZ, New Zealand's gender pay gap sits around 9.2% (as of recent measurements), meaning women earn, on average, about 91 cents for every dollar earned by men in comparable roles. When your KiwiSaver contributions are calculated as a percentage of your salary, earning less means saving less, automatically and continuously.

Here's how it compounds: if you're contributing 3.5% of your salary (the standard rate from April 2026 onward), and you're earning $60,000 while a male colleague earns $65,800 for similar work, you're contributing $2,100 per year while he's contributing $2,303. Add in the matching employer contribution, and that's a $406 annual difference. Over 35 years, accounting for investment returns, that gap alone could mean tens of thousands of dollars less at retirement.

And that's before considering career breaks or part-time work.

Women in New Zealand are significantly more likely than men to take career breaks for caregiving, whether for young children, ageing parents, or both (the so-called sandwich generation experience). According to Stats NZ, women perform the majority of unpaid caregiving work in New Zealand households.

A career break doesn't just pause your income; it creates a retirement savings gap in three ways:

• Lost contributions: While you're not earning, you're not contributing to KiwiSaver (unless you make voluntary contributions, which many can't afford when income drops)
• Lost employer match: No salary means no employer contribution, effectively doubling the loss
• Lost compound growth: The money you didn't contribute during that break would have had years or decades to grow through investment returns

A five-year career break in your thirties might mean $50,000-$80,000 less in your KiwiSaver at retirement, depending on contribution rates and investment returns. That's not including the lost wage progression that often happens when you step off the career ladder.

Even when women return to work after caregiving responsibilities, many do so part-time or in reduced-hour arrangements. Women make up the majority of part-time workers in New Zealand, and while part-time work can offer valuable flexibility, it also means proportionally lower KiwiSaver contributions.

Working 25 hours a week instead of 40 means your contributions are based on roughly 60% of a full-time salary, creating a compounding disadvantage that can last for years or even decades.

Before we dive into solutions, here's an important silver lining: New Zealand's public pension system, NZ Super, pays the same amount to everyone who qualifies, regardless of gender or work history. As of 2026, if you're 65 or older and meet the residency requirements, you'll receive the same NZ Super payment as anyone else in your living situation (single, partnered, etc.).

This is fundamentally different from countries where public pensions are based on lifetime earnings. In those systems, the gender pay gap and career breaks directly reduce government pension payments, creating a double disadvantage. In New Zealand, NZ Super provides a gender-neutral foundation, which means the retirement savings gap primarily affects your KiwiSaver and other personal savings, not your basic entitlement.

That said, NZ Super alone typically provides a modest standard of living. Most Kiwis need additional savings to retire comfortably, which is where addressing the KiwiSaver gap becomes crucial.

Understanding why the gap exists is empowering, but what matters most is what you can do about it. While systemic issues like the pay gap require broader societal change, there are concrete actions you can take right now to strengthen your retirement position. It's normal to feel like you're starting from behind, and it's also completely possible to make meaningful progress from wherever you are today.

The government will contribute 50 cents for every dollar you contribute to KiwiSaver, up to a maximum of $521.43 per year (as of the 2026 tax year). To get the full amount, you need to contribute at least $1,042.86 per year.

If you're working part-time or on a reduced income and your regular contributions don't reach this threshold, consider making voluntary contributions to capture the full government match. This is literally free money, and it's one of the few ways to offset the compounding disadvantage of lower earnings. Even if money is tight, treating this as a priority can pay significant dividends over time.

This is admittedly easier said than done, especially when household income drops. But if there's any way to maintain even small voluntary contributions during career breaks, the long-term impact can be substantial. Contributing just $20 or $40 per week during a five-year break can mean thousands more at retirement thanks to compound growth.

Some families find it helpful to reframe one partner's caregiving as economic contribution to the household, and budget for the caregiving partner to continue their KiwiSaver contributions as a family expense. This isn't feasible for everyone, but it's worth discussing if your household finances allow it.

Many KiwiSaver members are in default conservative funds that may not align with their actual time horizon until retirement. If you're in your 40s or 50s and still have 15-25 years until you need to access your KiwiSaver, you may have time to benefit from funds with higher growth potential (though also higher short-term volatility).

The relationship between time horizon and investment approach is an important concept to understand. Generally, the longer you have until retirement, the more time you have to ride out market fluctuations and potentially benefit from higher long-term returns associated with growth-oriented investments. However, the right fund type for your situation depends on multiple personal factors beyond just age.

Questions to consider when thinking about your fund type include: How many years until you plan to retire? How would you feel about seeing your balance drop 20% in a bad market year? Do you have other savings outside KiwiSaver? These are good topics to discuss with a licensed Financial Advice Provider who can assess your complete situation.

Under New Zealand's relationship property laws, KiwiSaver accumulated during a relationship (marriage or de facto partnership) is generally considered relationship property and can be split if the relationship ends. This provides some protection if you've taken career breaks for family reasons while your partner continued working and building their KiwiSaver.

However, understanding these rules before you need them is important. If you're in a long-term relationship where one partner has significantly higher KiwiSaver contributions due to career patterns, it's worth understanding how this might be addressed in the event of separation. Our post on retirement planning after divorce or separation covers this in more detail.

KiwiSaver is locked until you're 65 (with limited exceptions), which can be frustrating if you want to retire earlier or need flexibility. Building savings in more accessible accounts, whether through regular savings, investments in diversified funds, or other vehicles, gives you more options.

For some women, particularly those who are self-employed or working part-time, building a second income stream that can continue into retirement, either through investments, rental property, or flexible work, can provide both immediate and long-term security.

While this goes beyond retirement planning per se, your salary is the foundation of your retirement savings. Research shows women are less likely to negotiate starting salaries or ask for raises. Every $5,000 salary increase translates to hundreds more in annual KiwiSaver contributions, compounding over your career.

If it's been a while since you've had a frank conversation about your compensation, consider whether it's time. Resources like the Stats NZ income data can help you understand typical pay ranges for your role and experience level.

If you're single, whether by choice or circumstance, the retirement savings gap can feel even more daunting. You don't have a partner's income to fall back on, and you're managing all household costs on one income. The statistics around single women and retirement can be genuinely concerning.

But single women also have some advantages in retirement planning: complete control over financial decisions, no need to negotiate or compromise on saving priorities, and clear ownership of all assets. Many single women find that focused, intentional planning in their 40s and 50s can put them in a surprisingly strong position.

Our guide to retirement planning for single New Zealanders addresses the specific considerations and strategies that can help, from housing decisions to building community support networks that can reduce costs and increase quality of life in retirement.

If you're reading this and feeling discouraged about where your retirement savings currently stand, take a breath. First, the fact that you're thinking about this now, researching and learning, puts you ahead of many people who avoid retirement planning altogether. Second, time is still on your side if you're in your 40s, 50s, or even early 60s. Compound growth is powerful, and even starting or accelerating your savings now can make a meaningful difference.

The retirement savings gap for women is real, but it's not inevitable for you personally. Understanding the systemic factors, recognizing how they've affected your own financial journey, and taking intentional action from this point forward, those are the things within your control. And they matter enormously.

You've already made valuable contributions to your family and community, often at the expense of your own financial position. Now it's time to prioritize your future self with the same care and commitment you've shown others. You deserve financial security in retirement, and with planning and persistence, it's absolutely achievable.
