Bank Account Frozen After Death in NZ: Life Insurance Claims and Statutory Declarations

When a person dies in New Zealand, their sole bank accounts do not automatically pass to the next of kin. The bank will generally freeze the account when it is notified of the death, and the funds become part of the deceased's estate. Accessing them requires a release process — and which process applies depends on the account balance and the bank's requirements.

The same principle applies to life insurance payouts and KiwiSaver balances. Understanding the specific steps for each asset type can mean the difference between accessing funds within days and waiting months for High Court probate.

Joint accounts vs sole accounts

Joint accounts (held with a spouse or other person) are treated differently. The surviving account holder retains full access because the funds were already jointly owned. The bank will update the account name upon receiving the death certificate but will not freeze the surviving partner's access to the funds.

Sole accounts (held in the deceased's name only) are generally frozen when the bank is notified. You must go through a formal release process to access these funds. The process depends on the account balance relative to the $40,000 threshold.

The $40,000 threshold — what it means for bank accounts

Under the Administration (Prescribed Amounts) Amendment Regulations 2025, the informal administration threshold increased to $40,000 per financial institution. This means:

• If a bank holds up to $40,000 in the deceased's sole accounts, it may release the funds to the executor or another qualifying claimant without requiring a High Court Probate order.
• If the bank holds more than $40,000, it will require a High Court grant — probate if there is a valid will, or Letters of Administration if there is no will — before releasing the funds.

This threshold is assessed separately for each institution. If the deceased had $35,000 at BNZ and $38,000 at Westpac, both can be released informally — even though the combined total is over $40,000. Accounts at different banks are assessed independently.

Critical exception: Company shares, debentures, and government bonds remain capped at the legacy $15,000 limit under sections 64 and 64A of the Administration Act 1969. If the deceased held a share portfolio, that must be addressed separately even if each individual bank is up to $40,000.

How a statutory declaration releases bank funds

When the bank balance is up to $40,000, the executor or another qualifying claimant can request release of funds by providing a statutory declaration. This is a formal sworn statement, not simply a letter — it must be signed in the presence of a Justice of the Peace (JP), solicitor, or Notary Public.

Each bank has its own process, but generally they require:

• A certified copy of the death certificate
• The original will (or a certified copy)
• Your identity document (passport or driver licence)
• A completed statutory declaration form (usually provided by the bank or drafted by a solicitor)

The declaration states that you are the executor or entitled person, confirms the estimated total estate value, and indemnifies the bank against future claims from other parties. Once submitted, release timing varies by bank and document completeness.

If you cannot access a JP in person (relevant for rural or remote areas), arrange another authorised witness such as a solicitor or notary, or ask the institution what it will accept. Do not assume a video-witnessed declaration is sufficient.

Claiming life insurance after a death in NZ

Life insurance payouts in New Zealand work differently depending on whether the policy has a named beneficiary:

Named beneficiary policies: If the deceased named you as beneficiary directly on the policy (not via their will), the payout is not part of the estate — it is paid directly to you. Contact the insurer, provide the death certificate, and complete their claims form. This process is typically straightforward and does not involve probate, regardless of the amount.

No named beneficiary (estate only): If the policy pays to "the estate" rather than a specific person, the proceeds become part of the estate and may be subject to the estate-administration process. If the amount held with the institution exceeds $40,000, a High Court grant may be required.

To claim life insurance:

1. Contact the insurer directly. Most have a dedicated claims line.
2. Request their death claim form.
3. Provide: the certified death certificate, policy documents, your identity documents, and the completed claim form.
4. If the claim is being paid to the estate, also provide: the will (or letters of administration if no will), and the executor's details.

Life-insurance timing varies by insurer and the documents required. Do not assume the insurer will contact you — notify them proactively.

When to search for unknown policies

Many families do not know all the insurance policies their partner or parent held. Common places to look:

• Bank statements for premium direct debits
• Employment records (group life insurance is common through large employers)
• Mortgage documents (lenders often require life insurance; the bank may hold policy details)
• Old tax returns (insurance premiums may appear)
• Sorted.org.nz has guidance on locating lost policies

Some financial advisers will conduct a policy search on your behalf. There is no national registry of life insurance policies in New Zealand, so finding unknown policies requires investigation.

KiwiSaver death claims and statutory declarations

KiwiSaver balances up to $40,000 follow the same statutory declaration pathway as bank accounts, but each KiwiSaver provider has slightly different requirements. Balances over $40,000 generally require a High Court grant — probate if there is a will, or Letters of Administration if there is not.

The statutory declaration for KiwiSaver typically includes additional language — you must confirm that you will distribute the funds "in the due course of administration" and that no formal estate proceedings are underway. Providers may refuse to release funds if there is a family dispute or competing claim and may require formal court authority.

A practical sequence

If you are dealing with frozen bank accounts, a life insurance claim, and KiwiSaver simultaneously, the most efficient sequence is:

1. Order death certificates first — you need multiple certified copies ($35 each from BDM). Order at least three.
2. Notify all institutions — contact banks, the KiwiSaver provider, and insurers within the first week. This stops further transactions and starts the clock on their processing.
3. Assess each institution's balance — confirm whether each is up to $40,000.
4. Prepare statutory declarations — find a JP, solicitor, or other authorised witness. Ask in advance whether any witnessing or preparation fee applies.
5. Submit to each institution — different institutions require different forms. Some provide templates; others accept a generic declaration.

The timing for a small estate with multiple institutions varies by provider. A larger estate takes longer when a High Court grant is required; allow for the court process and each institution's release process.

The New Zealand Survivor Benefits Navigator includes a step-by-step checklist for releasing bank accounts, KiwiSaver, and life insurance — along with template language for statutory declarations that can be adapted to each institution's requirements.
