What Happens to Your KiwiSaver When You Die? The 2026 Estate Rules (NZ)

Your KiwiSaver does not go to a named beneficiary like life insurance. On death it is paid to your estate. Here is how the 2025 $40,000 probate threshold change affects your family in 2026.

Most people assume their KiwiSaver works like their life insurance: name a beneficiary, and the money lands with them when you die. It does not. KiwiSaver has no beneficiary nomination. When you die, your balance is paid to your estate and distributed under your will, or, if you have no will, under New Zealand's intestacy rules. That single difference catches many families out.

The good news is that a 2025 law change made smaller balances far easier for families to claim. This guide explains exactly what happens to your KiwiSaver when you die in 2026, how the new $40,000 probate threshold works, and why a valid will still matters even after the change.

TL;DR: Your KiwiSaver does not go to a named beneficiary. It is paid to your estate and distributed under your will (or intestacy rules if you have none). Since 24 September 2025, balances under $40,000 can be released without a High Court grant of probate, up from the old $15,000 limit. ²

Does KiwiSaver have a beneficiary like life insurance?

No. A life insurance policy lets you nominate beneficiaries, and on death the insurer pays those people directly, usually within weeks and outside your estate. KiwiSaver does not work that way.

KiwiSaver providers do not offer a binding beneficiary nomination. On death your KiwiSaver balance becomes an asset of your estate and is distributed under the terms of your will, or under the Administration Act 1969 if you die without one. ¹ In other words, $0 goes directly to a "beneficiary" the way an insurance payout would. It all flows through your estate first.

That matters because estates take time. Where life cover can reach a surviving partner in a fortnight, a KiwiSaver balance can sit untouched for months while the legal process catches up, exactly when a family most needs cash for the mortgage, the funeral, and day-to-day bills.

KiwiSaver and life cover are two different tools doing two different jobs. A KiwiSaver review can check both land with the right people, and the KiwiSaver health check shows where you stand today.

The 2025 probate threshold change: $15,000 to $40,000

On 24 September 2025 the Ministry of Justice raised the "small estates" threshold that lets banks, insurers and KiwiSaver providers release assets without a High Court grant of probate or letters of administration. The limit rose from $15,000 to $40,000. ²

The threshold is set under sections 65(2) and 65(5) of the Administration Act 1969. Below the cap, an institution holding a deceased person's asset may release it to eligible family members without anyone going to the High Court. ³

One important caveat: the $40,000 cap is not a clean universal cut-off. It applies to cash-type balances held by a bank, insurer or KiwiSaver provider. The cap for shares and bonds stayed at $15,000, and any real estate requires probate regardless of value. ³ KiwiSaver itself is squarely covered by the higher cap, but the wider estate may not be.

Why did this matter so much? The old $15,000 limit had been frozen since 2009, before the first KiwiSaver members had built up meaningful balances. As balances grew, more and more families were forced through the full High Court probate process simply to release a modest KiwiSaver account. ⁴ With the FMA reporting an average KiwiSaver balance of $36,349 at 31 March 2025, the old threshold was catching a large share of ordinary members. ⁹ The new $40,000 cap finally sits above that average.

For context on the scale of the scheme: KiwiSaver held $123.1 billion across 3.37 million members at March 2025. ¹⁰ A great many of those accounts now fall under the simpler release process.

How small KiwiSaver balances are released without probate

If your KiwiSaver balance is under $40,000 and it is your only sizeable asset, your family can usually claim it without going to court. The typical steps:

1. Contact the provider (Simplicity, Milford, Generate, Booster, Kernel, Fisher Funds, ANZ, or whoever holds the account) and notify them of the death.

2. Supply the death certificate and proof of relationship or entitlement.

3. Complete the provider's small-estate declaration — most providers require an indemnity or statutory declaration confirming who is entitled.

4. The provider releases the balance directly to the eligible family member, without probate or letters of administration. ³

How a KiwiSaver balance is paid out on death

The flow below shows where an estate splits depending on the balance and whether there is a will. (The under-$40,000 path assumes KiwiSaver is the only sizeable asset; real estate always needs probate, and shares or bonds still use the $15,000 cap. ³)

``` Member dies │ ▼ Provider contacted with death certificate │ ├── Balance UNDER $40,000 ──▶ Released to eligible family │ without a grant <sup>3</sup> │ └── Balance OVER $40,000 ───▶ Grant required: • With a will → Probate • No will → Letters of administration │ ▼ Funds distributed per the will, or per intestacy rules <sup>11</sup> ``` Source: Administration Act 1969; Ministry of Justice, 2025. ²³

Even under $40,000, providers do not all use the same forms or ask for the same declarations. "Small estate" does not mean instant: some providers require a statutory declaration witnessed by a JP before a balance will move.

When are probate or letters of administration still needed?

Once the relevant assets exceed the $40,000 threshold, the simple release process no longer applies and a High Court grant is required. ³ Which grant depends on whether there is a will:

• You left a valid will → the executor applies for a grant of probate, which confirms the will and their authority to deal with the estate.
• You did not leave a will → a family member applies for letters of administration, and the estate is distributed under the intestacy rules. ¹¹

Probate and letters of administration both take time and usually a lawyer. The $40,000 change removed that burden for many estates, but it did not remove it for everyone, and it certainly did not remove the need to plan.

Why does a valid will still matter for your KiwiSaver?

It is tempting to read "balances under $40,000 are easy now" as "I do not need a will." That is the wrong conclusion, and Public Trust, New Zealand's largest provider of wills and estate administration, said as much when the threshold rose: the higher cap does not remove the need for a will. ⁴

A will matters for your KiwiSaver because:

• A will decides who gets it. Without one, the law decides, not you (see intestacy below).
• Balances grow past the cap. With minimum contributions rising from 3% to 3.5% on 1 April 2026 and to 4% on 1 April 2028, plus employer contributions, the annual government contribution where you qualify, and returns, plenty of members will push past $40,000 sooner than they expect. ⁵⁷
• KiwiSaver is rarely your only asset. The $40,000 test applies to the relevant cash-type assets an institution holds. Add a car, a bank account and some savings and you are over the line; add shares or property and a grant is required regardless. ³
• It speeds everything up. A clear will with a named executor makes the whole process faster and cheaper for the people you leave behind.

If you have not reviewed your will alongside your KiwiSaver and insurance recently, it is worth doing all three together rather than in isolation.

How KiwiSaver interacts with your life insurance on death

Because the two assets behave so differently on death, they should be used to cover different needs.

• Life insurance pays your nominated beneficiaries directly and quickly, bypassing the estate. It is the right tool for the urgent costs: the mortgage, the funeral, replacing lost income for a partner and children.
• KiwiSaver flows through the estate and can take longer to release, especially over $40,000. Think of it as part of the longer-term inheritance, not the emergency fund.

Life cover is suited to the next 12 months of cash needs so a family is not waiting on probate to pay the mortgage, while the KiwiSaver balance sits as the slower-moving estate asset. The life insurance guide walks through cover types, and the life insurance service page explains how cover is compared across insurers.

The risk of dying without a will (intestacy)

If you die without a valid will, you die "intestate," and the Administration Act 1969 decides who gets your estate, including your KiwiSaver. The split is rigid and often surprises people.

Where someone dies intestate leaving a spouse or partner and children, the law currently directs: ¹¹

These figures are general and the rules above are legal, not financial, matters, so confirm how they apply to your estate with a lawyer. So a surviving partner does not automatically inherit everything. Once the prescribed $155,000 is paid, two-thirds of whatever is left, including a chunk of the KiwiSaver balance, goes to the children, even if your partner needs it to keep the family home running. ¹¹ For blended families and second marriages, intestacy can produce outcomes nobody intended. A will avoids the whole mess.

How KiwiSaver, insurance and estate planning fit together

Many people have a KiwiSaver account with one provider, a life policy with another, and a will (if they have one) that has not been updated in years, without checking whether the three line up. A review brings them together.

A review looks at your KiwiSaver provider and fund mix, confirms whether your life cover and beneficiary nominations are current, and flags whether your will needs updating so your savings reach the people you intend, quickly. Advice is independent across every major NZ KiwiSaver provider and insurer.

Frequently asked questions

Does my KiwiSaver go to my next of kin automatically when I die? Not automatically. Your KiwiSaver is paid to your estate, then distributed under your will or, if you have no will, under the intestacy rules of the Administration Act 1969. ¹¹¹ Your next of kin only receive it if your will or intestacy directs that.

Can I name a beneficiary on my KiwiSaver like I do on life insurance? No. KiwiSaver providers do not offer binding beneficiary nominations. The balance always passes through your estate. ¹ If you want money to reach specific people quickly and directly, that is what life insurance is for — see our life insurance guide.

What is the KiwiSaver probate threshold in 2026? $40,000. Since 24 September 2025, providers can release a KiwiSaver balance under $40,000 to eligible family without a High Court grant of probate. The previous limit was $15,000, unchanged since 2009. Note the cap covers cash-type balances; shares and bonds remain at $15,000 and real estate always needs probate. ²³⁴

What happens to my KiwiSaver if I die without a will? A family member must apply for letters of administration (if the balance is over $40,000), and your estate is distributed under intestacy rules. A surviving partner takes the chattels plus a prescribed $155,000 and one-third of the residue, with children taking the other two-thirds. These are legal questions, so confirm the detail with a lawyer. ¹¹

Will my KiwiSaver balance push me over the $40,000 threshold? Quite possibly. The average KiwiSaver balance was $36,349 at March 2025, and minimum contributions rise from 3% to 3.5% on 1 April 2026 and to 4% in 2028, on top of the annual government contribution where you qualify, so balances are climbing. ⁵⁷⁹ Add other assets and most estates exceed $40,000.

Does my partner pay tax when they inherit my KiwiSaver? New Zealand has no inheritance or death tax, so the balance itself is not taxed on transfer. Your PIE tax (at your PIR of 10.5%, 17.5% or 28%, defaulting to 28% if no PIR is supplied) applies to investment income up to the date the account is closed, not to the inheritance. ⁸
