Best Cross-Border Probate Guide for Executors with Assets in Australia and New Zealand

If the deceased held assets in both Australia and New Zealand — bank accounts, property, shares, KiwiSaver, or superannuation — you may need court authority in both jurisdictions before larger assets can be released. The concept that connects them is called probate resealing: a grant of probate issued in one country can be formally recognised by a court in the other, but it does not happen automatically. You may need to apply, file documents, and pay fees in both jurisdictions.

The Australian Dies in New Zealand — Family Emergency Guide maps this dual-jurisdiction process from start to finish. Here is why the resealing step trips up executors and what a purpose-built guide needs to cover.

How Probate Resealing Works Between Australia and New Zealand

Probate resealing is the legal mechanism that allows a grant of probate (or letters of administration) from one country to be recognised and enforced in the other. For larger balances, a New Zealand bank will generally not release funds to an executor holding only an Australian probate grant, and an Australian bank will generally not release funds to an executor holding only a New Zealand grant.

Direction 1: NZ grant resealed in Australia. If probate was first granted in New Zealand (because the deceased was domiciled there or died there with NZ assets as the primary estate), the executor applies to reseal that grant in the relevant Australian state Supreme Court. Each state has its own filing requirements, fees, and processing times. The most common reason for requisitions (the court asking for additional information) is incomplete document authentication.

Direction 2: Australian grant resealed in NZ. If probate was first granted in Australia, the executor applies to reseal it in the Wellington High Court. The fee is a flat NZD $50, but the court requires a New Zealand address for service — which means the executor either needs a NZ-based solicitor or a trusted contact in New Zealand who can receive court correspondence.

The Document Authentication Bottleneck

One recurring delay in cross-border probate is document authentication. The court handling the resealing application may require the foreign probate grant and supporting documents to be properly legalised before it will process the application.

The Section 148 shortcut that usually does not work in practice: Under Section 148 of the NZ Evidence Act 2006, Australian and New Zealand public documents are technically admissible in each other's courts without formal legalisation. In theory, this means you can file an NZ death certificate directly with an Australian probate court without an Apostille.

In practice, court registry staff and judges' associates frequently require an Apostille anyway. The statute creates a legal right, but exercising it requires the specific court officer handling your file to know about it and accept it — and many do not. Executors who rely on Section 148 without a backup Apostille risk having their application returned with a requisition, adding weeks to the timeline.

The pragmatic approach: Apply for a Hague Apostille on the foreign documents the relevant court requires before filing the resealing application. The New Zealand Department of Internal Affairs (DIA) Authentication Unit handles New Zealand Apostilles in Wellington; confirm its current fee and processing time before applying. DFAT handles authentication for Australian documents going to NZ. The time savings from avoiding a requisition can be significant.

What Executors Get Wrong

Three errors account for most resealing delays on the trans-Tasman corridor:

Filing in the wrong Australian state. The resealing application must be filed in the state where the deceased's Australian assets are located — not the state where the executor lives. If the deceased had a bank account in NSW and property in Queensland, you may need to file in both states, or file in one and use that resealed grant to access assets in the other (rules vary by state).

Submitting an unauthenticated NZ death certificate. The court requires either an original or a properly authenticated copy. A plain photocopy, even if certified by a JP, is not sufficient for probate court filing in most states. An Apostilled original or an Apostilled certified copy clears the threshold.

Ignoring the NZ-side obligations. Even if the primary estate is in Australia, the executor has obligations in New Zealand: finalising the deceased's Inland Revenue (IRD) tax position, closing NZ bank accounts, resolving any KiwiSaver death benefit claim, and notifying NZ government agencies. These NZ obligations exist independently of the Australian probate process and have their own deadlines and documentation requirements.

Who This Is For

• Executors managing an estate where the deceased held bank accounts, property, shares, or retirement savings in both Australia and New Zealand
• Next of kin who discovered the deceased had NZ assets (KiwiSaver, NZ bank accounts, investment property) that were not mentioned in the Australian will
• Solicitors handling a trans-Tasman estate who need a practical reference for the resealing process, document requirements, and common requisition triggers
• Families where the deceased was an Australian citizen living in New Zealand (or vice versa) and the estate spans both countries by default

Who This Is NOT For

• Executors where all assets are in one country — if the deceased had no NZ assets, Australian domestic probate guides cover everything; if no Australian assets, NZ domestic probate applies
• Estates below the relevant institution's small-estate threshold — approximately NZD $15,000 for NZ holdings and AUD $100,000 for certain Australian bank, share, or superannuation holdings — may be released without a formal probate grant, so resealing may not be necessary
• Families dealing with a disputed will or contested beneficiaries — those situations require litigation lawyers in each jurisdiction, not a process guide

State-by-State Resealing Complexity

Australian probate is not a federal system — each state Supreme Court has its own rules. The practical differences that matter for trans-Tasman resealing:

The common thread: authentication of the NZ documents is the most frequent requisition trigger across all states. Getting the Apostille before filing avoids the most common delay.

The Complete Process Map

For an executor handling assets in both countries after an Australian dies in New Zealand:

1. Obtain the NZ death certificate (BDM93D paper path if ordering from Australia)
2. Authenticate the certificate if required (Apostille from the NZ DIA Authentication Unit)
3. Apply for NZ probate (if the deceased had NZ assets requiring a local grant) — or wait for Australian probate to be granted first if the primary estate is in Australia
4. File for resealing in the other country's court
5. Resolve NZ-side obligations — IRD final return, NZ bank closures, KiwiSaver claim
6. Resolve AU-side obligations — ATO final return, Centrelink notification, superannuation claims, AU bank account closures
7. Distribute the estate once both jurisdictions have cleared the executor to release assets

Steps 3 and 4 are where most executors need guidance, and the order depends on where probate is sought first. The Australian Dies in New Zealand — Family Emergency Guide maps the decision logic — which jurisdiction to seek probate in first (usually where the deceased was domiciled, but not always), what documents each court requires, and the specific resealing forms for each Australian state.

When You Need a Lawyer vs When You Do Not

You probably do not need a lawyer if: The estate is straightforward (one will, clear beneficiaries, standard assets like bank accounts and super), the resealing is in one state, and you are comfortable filing court documents yourself. Court registry staff can explain the filing requirements, and the guide provides the document templates and checklists.

You probably need a lawyer if: The deceased had property in both countries (conveyancing crosses into specialist territory), the will is being contested, there are beneficiaries in both countries with competing claims, the estate includes a business, or the NZ and Australian wills contain conflicting provisions. A solicitor experienced in trans-Tasman estates will save more in avoided errors than their fee costs.

Frequently Asked Questions

How long does probate resealing take in Australia?

Processing times for an uncontested resealing application vary by Australian state and the completeness of the filing. If the court raises a requisition, providing the additional information adds delay; contested applications or complex estates can take substantially longer.

Can I access the deceased's NZ bank accounts before probate is granted?

For small balances (typically under NZD $15,000, though thresholds vary by bank), most NZ banks will release funds to the next of kin upon presentation of the death certificate and proof of identity, without requiring a formal grant of probate. For larger balances, the bank's deceased estates department will freeze the account until they receive either a NZ probate grant or a resealed foreign grant.

Do I need separate probate grants in each Australian state where the deceased had assets?

Not necessarily. Once a NZ grant is resealed in one Australian state, that resealed grant can generally be used to access assets in other states — but some institutions may require the grant to be filed in the state where the specific asset is held. Check with each institution before assuming a single resealing covers everything.

What about KiwiSaver — does that require probate?

KiwiSaver death benefit claims are processed by the scheme provider, not the courts. The provider requires the death certificate, proof of the claimant's identity and relationship to the deceased, and evidence of any binding nomination. If there is no nomination, the provider distributes according to the deceased's will or intestacy rules. A formal probate grant may not be needed for the KiwiSaver claim itself, but the provider may request one if the estate is complex or the claim is disputed.

What happens if the deceased died without a will (intestate)?

Intestacy rules differ between Australia and New Zealand. NZ assets are distributed under NZ intestacy law (Administration Act 1969), and Australian assets are distributed under the intestacy rules of the relevant Australian state. The executor — or, in intestacy, the administrator appointed by the court — must apply for letters of administration in each jurisdiction rather than probate. The resealing process works the same way, but with letters of administration instead of a probate grant.
