Last Will and Testament (New Zealand)

A Last Will and Testament in New Zealand is a legal document by which a person (the testator) directs how their estate is to be distributed after death and appoints an executor to administer the estate. Governed by the Wills Act 2007 — New Zealand's primary statute on wills — a Last Will and Testament must meet specific formal execution requirements to be valid and admissible to probate before the High Court of New Zealand.

Under Section 11 of the Wills Act 2007, a will is formally valid if the testator is 18 years of age or older (or is or has been married or in a civil union, or is on active military service), the will is in writing, the testator signs it or directs another person to sign on their behalf in their presence, and two or more witnesses are present at the same time and each sign the will in the testator's presence. A beneficiary of the will — or their spouse or civil union partner — should not act as a witness, as this may invalidate the gift to that beneficiary under Section 12 of the Wills Act 2007.

Beyond formal validity, a New Zealand Last Will and Testament is subject to several statutes that can affect its operation. The Family Protection Act 1955 allows certain family members — including spouses, civil union partners, de facto partners, and children — to apply to the High Court for provision from the estate if the will fails to make adequate provision for their proper maintenance and support. The Law Reform (Testamentary Promises) Act 1949 allows claims by persons who provided services to the deceased in expectation of a testamentary benefit. The Property (Relationships) Act 1976 gives surviving spouses and partners the right to elect to receive their relationship property share rather than accept the gift under the will.

After the testator's death, the executor named in the will must apply to the High Court of New Zealand for a Grant of Probate under the Administration Act 1969. Probate formally recognises the will as valid and authorises the executor to collect, administer, and distribute the estate. The Public Trust or a private trustee company may act as executor where no individual is willing or able to do so. New Zealand does not have an estate or inheritance tax, but the executor must ensure all outstanding income tax obligations of the deceased are settled with Inland Revenue Department (IRD) before distributing the estate.

New Zealand has no estate or inheritance tax. However, the executor must ensure all outstanding income tax obligations of the deceased are settled with Inland Revenue Department (IRD) before distributing the estate, and must file a final income tax return on the deceased's behalf. The Administration Act 1969 governs the administration of both testate and intestate estates in New Zealand. The executor must apply to the High Court of New Zealand for a Grant of Probate, which formally confirms the will's validity and authorises the executor to deal with the deceased's assets. The Public Trust and private trustee companies can act as professional executors under the Trustee Act 1956.

Every adult New Zealander should have a Last Will and Testament. Without a valid will, the estate is distributed according to the intestacy rules in the Administration Act 1969, which follow a fixed statutory order of priority that may not reflect the deceased's wishes or family circumstances.

A Last Will and Testament is particularly important when you acquire significant assets — real property, investments, a business interest, or substantial savings — and wish to control who inherits them. Under New Zealand's Wills Act 2007, you have broad testamentary freedom to leave your estate to whomever you choose, subject to the Family Protection Act 1955 and the Property (Relationships) Act 1976.

You should make or update a Last Will and Testament when you marry or enter a civil union. Under Section 18 of the Wills Act 2007, marriage or civil union does not automatically revoke an existing New Zealand will (unlike in some other jurisdictions), but significant changes in your personal circumstances warrant reviewing your testamentary intentions and ensuring your will reflects your current wishes.

Parents with minor children should have a Last Will and Testament that appoints a guardian for those children under Section 31 of the Care of Children Act 2004. Without a guardian appointment in the will, decisions about who cares for minor children may be left to the Family Court.

You should update your Last Will and Testament if your family circumstances change — including separation, divorce, the death of a beneficiary or executor, or a significant change in the composition of your estate. A codicil (a supplementary document amending a will) may be used for minor changes, but a new will is preferable where changes are substantial. A will should also be reviewed if you acquire overseas assets, as different countries apply their own succession laws and a New Zealand will may not automatically govern foreign assets.

A Last Will and Testament should also be reviewed if you acquire overseas property. Different countries apply their own succession laws, and a New Zealand will may not automatically govern foreign assets under those countries' legal systems. A separate will in the relevant jurisdiction may be required. Review your will if the legal context changes, including amendments to the Property (Relationships) Act 1976 or changes to your KiwiSaver fund beneficiary nominations under the KiwiSaver Act 2006. The Public Trust and MBIE publish guidance on estate planning and the importance of maintaining a current, properly executed will.

A valid New Zealand Last Will and Testament under the Wills Act 2007 must include the following key elements.

**Testator identification.** The testator's full legal name, current address, and a statement that the document is their last will and testament, made with full testamentary capacity.

**Revocation clause.** A statement revoking all prior wills and testamentary documents. This ensures only the current document governs the estate and prevents confusion where previous wills exist.

**Appointment of executor.** The full name and address of the executor (and a substitute executor in case the primary executor is unable or unwilling to act). The executor has legal authority to collect, administer, and distribute the estate and is subject to fiduciary duties under the Trusts Act 2019.

**Specific gifts and bequests.** Any specific items of property — real estate, vehicles, jewellery, artworks, business interests — or sums of money to be given to named beneficiaries. Specific bequests take effect before the residuary estate is distributed.

**Residuary estate.** A direction as to who receives the remainder of the estate after all specific gifts, debts, liabilities, administration expenses, and taxes have been paid. The residuary clause is critical — without it, any estate assets not covered by specific gifts fall into intestacy under the Administration Act 1969.

**Guardianship of minor children.** Where the testator has children under 18 years, an appointment of a guardian under Section 31 of the Care of Children Act 2004. This appointment is subject to confirmation by the Family Court but carries significant weight.

**Funeral and burial wishes.** An optional statement of the testator's preferences regarding funeral arrangements, burial or cremation, and organ donation under the Human Tissue Act 2008. While not legally binding on executors, these wishes are usually followed.

**Execution requirements.** The testator's signature (or direction to another person to sign in their presence), the date of execution, and the signatures of two independent witnesses who were present at the same time and signed in the testator's presence, as required by Section 11 of the Wills Act 2007. A beneficiary or their spouse should not witness the will.

The forms-legal.com Last Will and Testament (New Zealand) provides a professionally drafted template that meets the Wills Act 2007's formal requirements and addresses Family Protection Act 1955 and Property (Relationships) Act 1976 considerations.

**Trustee powers.** Where the estate includes assets held on trust for minor beneficiaries, the will should grant broad investment and management powers to the executor/trustee under the Trusts Act 2019, which came into force on 30 January 2021 and sets out trustees' mandatory and default duties in New Zealand.

**Digital assets.** A modern New Zealand will should address digital assets including cryptocurrency, online accounts, and subscription services, and provide the executor with access credentials or instructions under the Property Law Act 2007.

**Foreign assets.** Where the testator owns property overseas, the will should note that separate legal advice and possibly a separate will in the relevant jurisdiction may be required, and that the Inland Revenue Department (IRD) should be consulted regarding foreign tax obligations.

New Zealand Last Will and Testament documents must satisfy the formal validity requirements of the Wills Act 2007 and withstand potential challenges under the Family Protection Act 1955 and the Property (Relationships) Act 1976. The starting point for every New Zealand will is testamentary capacity — the testator must understand the nature of making a will, the extent of the property being disposed of, the claims of those who might expect to benefit, and the effect of the dispositions made. The leading English authority on testamentary capacity, Banks v Goodfellow (1870) LR 5 QB 549, has been consistently adopted and applied by New Zealand courts, including the High Court of New Zealand and the Court of Appeal. In Banks v Goodfellow, the Court of Queen's Bench held that testamentary capacity requires a sound and disposing mind — the testator must understand what they are doing, what property they have, who might naturally be expected to benefit, and how the will distributes the estate. New Zealand courts apply this four-part test when a will is challenged on capacity grounds, and medical evidence about the testator's condition at the time of execution is regularly examined in contested probate proceedings before the High Court of New Zealand.

Section 11 of the Wills Act 2007 sets out the formal execution requirements: the will must be in writing, signed by the testator or by a person directed by the testator in their presence, with the intention of executing the will, in the presence of two or more witnesses who are both present at the same time and who each attest and sign the will in the testator's presence. Section 12 of the Wills Act 2007 provides that a beneficial disposition to a witness, or their spouse or civil union partner, is void — though the will itself remains valid. Section 14 of the Wills Act 2007 confers a judicial discretion to admit a non-compliant document to probate if the court is satisfied that the document expresses the testator's testamentary intentions, but this discretion is exercised cautiously and is not a reliable substitute for compliance.

The Family Protection Act 1955 (FPA 1955) operates as a significant constraint on testamentary freedom in New Zealand. Section 4 of the FPA 1955 allows spouses, civil union partners, de facto partners, and children of the deceased to apply to the High Court for provision from the estate if the will fails to make adequate provision for their proper maintenance and support. The court's jurisdiction under the FPA 1955 is broad and the outcomes are fact-specific, but testators who completely exclude a surviving spouse or dependent children from the will face a high risk of a successful FPA claim being mounted against the estate during the probate and administration process under the Administration Act 1969.

New Zealand Last Will and Testament documents are frequently invalidated or challenged because of avoidable errors in execution, capacity, and estate planning. The following mistakes arise regularly in High Court probate proceedings and estate disputes.

1. Failing to satisfy the testamentary capacity standard from Banks v Goodfellow. A will executed by a testator who lacked capacity — because of dementia, serious mental illness, or undue influence by a beneficiary — will be invalid. New Zealand courts apply the four-part Banks v Goodfellow test and examine medical records from the time of execution. The correct approach is to obtain a formal capacity assessment from a medical professional before executing a will where there is any doubt about the testator's mental state, and to have the solicitor record contemporaneous file notes about the testator's understanding of the dispositions.

2. Beneficiaries or their spouses acting as witnesses. Section 12 of the Wills Act 2007 voids any beneficial gift to a witness or their spouse or civil union partner. A spouse who witnesses a will loses their gift under the will, even though the will itself remains valid. The consequence is that the spouse may receive less under the will than they would receive on intestacy. Witnesses must be independent adults who take no benefit under the will.

3. Witnesses not being present at the same time. Section 11 of the Wills Act 2007 requires both witnesses to be present at the same time when the testator signs (or acknowledges the signature). Having the testator sign first and then obtaining witness signatures separately — even on the same day — may invalidate the will. All three parties must be in the same room at the moment of attestation.

4. Not revoking previous wills expressly. Without an express revocation clause, earlier wills are not automatically revoked in New Zealand (unlike some other jurisdictions where marriage revokes a prior will). Multiple inconsistent wills create confusion in estate administration and may require expensive High Court proceedings under the Administration Act 1969 to resolve which document prevails. Every new will should contain a clear clause revoking all previous wills and codicils.

5. Ignoring the Family Protection Act 1955. Testators who completely exclude a spouse, civil union partner, de facto partner, or child from the will without making adequate provision risk a successful Family Protection Act 1955 claim during estate administration. The High Court has broad discretion to order provision from the estate. The correct approach is to seek legal advice about FPA 1955 exposure before finalising distributions, and to document the reasons for any reduction or exclusion in a letter of wishes held with the solicitor.

6. Failing to appoint a substitute executor. If the primary executor predeceases the testator, is unwilling to act, or lacks capacity, and no substitute is named, the High Court of New Zealand must appoint an administrator under the Administration Act 1969 — a process that is slower and more expensive than probate under a named executor. Always appoint a substitute executor or authorise the executor to appoint a professional trustee company such as the Public Trust.

7. Not addressing the residuary estate. Specific bequests that exhaust the estate without a residuary clause leave any remaining property undistributed — it falls into intestacy and is distributed under the Administration Act 1969 rather than the testator's wishes. Every will must include a residuary clause addressing what happens to the balance of the estate after all specific gifts and liabilities are paid.

8. Overlooking the Property (Relationships) Act 1976. A surviving spouse or de facto partner may elect under the Property (Relationships) Act 1976 to receive their relationship property entitlement (typically 50% of relationship property) rather than accepting the gift under the will. Testators should obtain advice on how the PRA 1976 interacts with their estate plan, particularly where the will attempts to favour children from a prior relationship over the current surviving partner.

9. Failing to update the will after major life events. Marriage, civil union, de facto relationships, separation, divorce, the birth of children, and the death of a named beneficiary or executor all affect the operation of a New Zealand will. The Wills Act 2007 does not automatically revoke a will upon marriage in New Zealand (unlike the position in England and Wales). A will should be reviewed whenever there is a material change in the testator's personal or financial circumstances.

10. Not addressing digital assets and KiwiSaver. Modern New Zealand estates frequently include cryptocurrency holdings, online accounts, and subscription services that are not addressed in traditionally drafted wills. KiwiSaver fund balances pass under separate beneficiary nominations under the KiwiSaver Act 2006 and are not automatically distributed under the will. The executor needs access instructions for digital assets, and the will should confirm what directions apply. Failure to address these assets can result in permanent loss of access to digital property.
