When divorce rewrites retirement
Later life, or ‘grey’, divorce is no longer unusual in New Zealand. Around 3,000 people divorce later in life each year, accounting for about 40% of all divorces. While overall divorce numbers are falling, separations among people aged 50 and over have risen 7.1% over the past decade.
Retirement, children leaving home, financial pressure and changing social attitudes all play a role in these figures. But while grey divorce may be more common, its impact on retirement planning can be severe – especially if action isn’t taken quickly.
Once a long term relationship ends, retirement plans built for two incomes, one household and shared assets often no longer stack up.
Women are hit hardest
The financial fallout from divorce tends to fall disproportionately on women. A 2020 Retirement Commission study found women’s incomes drop by around 29% after divorce, while men’s income is shown to increase by an average 15%. That often means women needing to work longer, retire later, or stretch smaller retirement savings across more years.
With less time to rebuild KiwiSaver or other retirement saving balances, fewer working years left, and rising health and housing costs ahead, recalibrating your financial plan early is critical.
Build a post divorce budget straight away
One of the biggest shocks after divorce is the cost of living alone. Rent or mortgage payments, power, insurance and rates suddenly absorb a much larger share of a single income. Inflation also bites harder when there’s no second wage to cushion rising costs.
Create a new, realistic budget as soon as possible that reflects your solo income and expenses. Build or rebuild an emergency fund, even if it starts small. Online tools like Sorted’s budget planner can help you clarify what’s sustainable for you.
Remember: if retirement is still a few years away, your budget needs to hold not just today, but well into older age, when healthcare and housing costs typically rise.

Get serious about debt
If you come out of a divorce with debt, reducing it should be a top priority. Debt repayments restrict cash flow, limit your ability to save, and add pressure precisely when financial flexibility matters most.
The lower your debt, the greater your resilience, both before and during retirement.
Rebuild your retirement plan sooner than later
Divorce forces a full financial reset. Everything from retirement age to income expectations needs to be rethought.
This is especially important for women, who often face lower lifetime earnings and KiwiSaver balances due to things like career breaks. Delaying sorting out your next steps only compounds the problem. But even modest changes, like increasing KiwiSaver contributions or adjusting investment settings, can make a meaningful difference over time.
Products like Lifetime Retirement Income and Lifetime Home can be useful to consider as you rebuild your retirement plan and can offer greater certainty and security for your retirement income.
What happens to KiwiSaver after divorce?
KiwiSaver is often the second largest asset after the family home.
Under the Property (Relationships) Act, KiwiSaver contributions made during the relationship (and investment gains on those contributions) are treated as relationship property and are usually split 50:50.
You and your former partner can agree to offset KiwiSaver with other assets of equal value – such as cash or home equity – but both parties must agree. Each option has long‑term consequences, so it’s important to understand the trade‑offs.
If you’re able to, increasing KiwiSaver contributions or other pension savings post‑divorce can help rebuild retirement savings and make the most of compounding over time.
Update legal documents and insurance immediately
After a divorce, update your will and enduring powers of attorney straight away. Former partners are often still named, and inaction can have unintended consequences years later.
Review all insurance policies – especially life, health and income protection. Joint policies may need splitting, replacing or altering to reflect your new situation.
Supporting adult children - without sacrificing yourself
It’s natural to want to protect your kids financially. But this shouldn’t come at the expense of your own retirement security. Focus first on a fair asset split between parents, then look for ways to support children later if you can afford it. It can be beneficial to put this idea on hold for now.
Get financial advice alongside legal advice
Divorce decisions are often made under stress, fatigue and emotion. A lawyer helps finalise the settlement, but a financial adviser helps ensure it works for the rest of your life.
This is particularly important when weighing up whether to keep the family home, rebuild KiwiSaver, or reshape your retirement timeline. Good advice now can prevent costly mistakes later and help you move forward with more confidence.
