What Happens to KiwiSaver When Someone Dies?

KiwiSaver surprises families twice: first, that the money doesn't go automatically to a spouse or named person; and second, how much paperwork the payout can involve.

Where the money goes

This matters for planning and for expectations: a partner cannot simply claim the KiwiSaver. It joins the estate alongside the bank accounts and the house, and follows the same rules.

How the payout works

The full balance — contributions, employer contributions, government contributions and returns — becomes payable on death. What the provider needs depends on the balance:

• Under $40,000: the provider can pay out without probate. Typically they'll ask for the death certificate, the will, ID for the person claiming on behalf of the estate, and a statutory declaration. (This threshold rose from $15,000 in September 2025.)
• Over $40,000: the provider requires probate or letters of administration before paying the estate. With KiwiSaver balances now routinely six figures, this alone makes a grant necessary for many estates — see do you need probate?

Payment timing varies by provider — typically a few weeks after they have everything they need. Funds are usually paid into the estate's bank account.

Practical notes for executors

• Find the provider. People often don't know where their KiwiSaver is. The person's myIR account, bank statements (look for contribution deductions), or Inland Revenue can identify the scheme.
• Tell IRD about the death. This also stops any government contribution issues and matters for the final tax return — part of the Financial close-out step.
• The balance keeps moving. Until paid out, the money stays invested and can go up or down. If markets worry you, ask the provider about switching the holding to cash while the estate is administered — a judgement call for the executor.
• Check for life insurance too. Some KiwiSaver providers and employers bundle separate life cover. Unlike KiwiSaver itself, life insurance with a named beneficiary is paid directly to that person, outside the estate.

A common misconception

"The estate is small, it's only KiwiSaver, surely we don't need a lawyer." Maybe — if the balance is under $40,000, the release process is genuinely simple and you can usually do it yourself. Over $40,000 the court grant is unavoidable, but for a simple estate a fixed-fee probate service can keep the cost under $1,000.

What to do next

Locate the provider, notify them with a death certificate, and ask for their deceased estate requirements and current balance in writing. That balance — over or under $40,000 — tells you which path the whole payout follows.
