Retirement planning for women
The retirement savings gap between men and women in New Zealand is real — but it is not inevitable. Here's what's behind it, and what to do about it.
On average, women in New Zealand retire with significantly less savings than men. The gap is not small, and it is not accidental — it is the predictable result of a set of structural and social factors that disadvantage women financially over the course of a working life.
Understanding those factors clearly is the first step toward doing something about them. And for many women, the picture is considerably more improvable than it might initially appear.
Why the gap exists
Several factors combine to produce the retirement savings gap, and they reinforce each other in ways that make the cumulative effect larger than any single factor would suggest.
- The gender pay gap. Women in New Zealand earn less than men on average. Lower income means lower KiwiSaver contributions, lower employer contributions, and a smaller base from which savings can grow. Over a full career, this compounds significantly.
- Career interruptions. Women are more likely to take time out of paid work — or reduce their hours — to care for children or other family members. Every period out of the workforce is a period without KiwiSaver contributions, without employer matching, and without the compounding growth that those contributions would have generated.
- Part-time work. Women are more likely than men to work part-time, often for reasons connected to caring responsibilities. Part-time income means proportionally lower KiwiSaver balances, even when contribution rates are the same.
- Longer life expectancy. Women in New Zealand live longer than men on average. This means retirement savings — whatever their size — need to stretch further. A smaller balance lasting a longer period is a more acute challenge than the same balance for a shorter one.
These are structural realities that require conscious planning to navigate — and the earlier that planning begins, the more effectively it can compensate.
What women can do about it
- Start early and contribute consistently. The compounding effect of long-term, consistent contributions is the most powerful force available — see when to start saving for a clear picture of what early action produces. Every year of consistent contribution is a year of compounding that cannot be recovered if missed.
- Review contribution rates regularly. As income increases over a career, contribution rates can be increased to compensate for earlier periods of lower saving. Moving from 3.5% to 6% or 8% at a higher income level can go a long way toward closing a gap that opened during lower-earning years.
- Plan around career breaks rather than hoping they won't affect savings. If a career break is anticipated — for parental leave, caring responsibilities, or any other reason — the most effective response is to plan for it in advance. Contributing at a higher rate before and after a break, or making voluntary lump sum contributions to KiwiSaver during a break, can significantly reduce the impact.
- Plan as a couple — carefully. For women in relationships, retirement planning as a couple can be valuable — but it should be approached with clear eyes. Retirement savings are individual assets in New Zealand. In the event of separation, KiwiSaver balances are typically treated as relationship property, but the dynamics of a couple's financial situation can change. Having a clear personal retirement picture, independent of a partner's, is important.
- Know your number. Perhaps most importantly: knowing exactly what you need to retire on your own terms — and what you are currently on track to accumulate — makes every other decision more concrete and more actionable. Vague concern is far less useful than clear understanding.
The spending dimension
There is one area where women, on average, have an advantage that is rarely framed as such: research consistently shows that women tend to make more considered spending decisions than men, and are more likely to direct money toward things that genuinely matter to them rather than status or impulse.
This tendency toward intentional spending — toward knowing what enough looks like and living accordingly — is precisely the behaviour that most accelerates retirement security. It reduces the gap between income and savings, it lowers the retirement income needed, and it builds financial confidence over time. It is worth recognising as the genuine asset it is.

ThatDay is a free retirement planning platform built for New Zealanders. It works equally well for individuals and couples, and lets you set any retirement age — giving you a clear, personal picture of what you need and what you are currently on track to accumulate. For women navigating the specific challenges described in this article, that clarity is a particularly valuable starting point.
Its financial assumptions were independently validated by the University of Auckland Business School's Master of Applied Finance programme.

A final thought
The retirement savings gap between men and women in New Zealand is real, but it is not fixed. The women who retire most securely are not necessarily those who earned the most or avoided every structural disadvantage — they are those who understood their situation clearly and planned deliberately within it.
That kind of deliberate planning is available to every woman in New Zealand, at any age and at any income level. And it starts with knowing where you stand.
