Codicil to Will (New Zealand)

A Codicil to Will in New Zealand directs how a person's property, money, and personal effects are distributed after death and names the executor responsible for administering the estate, with formal validity and execution governed by the Wills Act 2007. It directs the distribution of the testator's estate to named beneficiaries upon death.

The Wills Act 2007 introduced a significant reform unique to New Zealand testamentary law: the curative discretion under s. 14, which allows the High Court to admit to probate a document or a group of statements that does not comply with the formal execution requirements of s. 11 if the court is satisfied that the document or statements embody the testamentary intentions of the deceased. This judicial power was not available under the previous statutory regime and provides a last resort where informal amendments to a will can be validated — for example, handwritten notes in the margin of the original will or an unsigned typed document. However, the s. 14 application involves High Court proceedings and is expensive and uncertain. A properly executed codicil under s. 11 remains the only reliable method of amending a New Zealand will.

Probate of the will and any codicils is granted by the High Court of New Zealand under the Administration Act 1969 and the High Court Rules 2016 (Part 19). The executor named in the most recent valid testamentary instrument — whether the original will or a subsequent codicil — applies for a grant of probate. Both the original will and all codicils must be submitted to the High Court Registry with the probate application. Inland Revenue Department (IRD) does not impose inheritance tax or estate duty in New Zealand — the Estate Duty Act 1968 was effectively abolished for deaths occurring after 17 December 1992 — but executors must confirm the deceased's final income tax return and any tax obligations are satisfied before distributing the estate.

The Family Protection Act 1955 allows certain family members — spouses, civil union partners, de facto partners, and children — to challenge a will (or codicil) on the grounds that the testator failed to make adequate provision for them. A codicil that reduces a beneficiary's share may increase the risk of a Family Protection Act claim, particularly where the reduction affects a spouse, partner, or financially dependent child. The Property (Relationships) Act 1976 may also affect the validity of testamentary dispositions where relationship property is involved. A New Zealand Codicil to Will is distinct from a New Zealand Enduring Power of Attorney, which governs decision-making during the testator's lifetime and operates under the Protection of Personal and Property Rights Act 1988.

A New Zealand Codicil to Will under the Wills Act 2007 is needed whenever a testator wishes to make a targeted amendment to an existing will without revoking and rewriting the entire document, and the change can be precisely described in a self-contained instrument that will be read with the original will.

When an executor named in the original will has died, has indicated unwillingness to act, or has become legally incapacitated under the Protection of Personal and Property Rights Act 1988, a codicil appointing a substitute executor avoids the cost and delay of rewriting the entire will. Under the Administration Act 1969, a vacancy in the office of executor can also be filled by the High Court appointing an administrator, but a codicil is the simpler and more certain option if the testator retains capacity.

When a specific bequest in the will has become outdated — for example, a gift of a specific vehicle, artwork, or investment that the testator has since sold — a codicil can revoke the outdated specific gift and substitute either a new specific bequest or a pecuniary legacy. This avoids ademption (the failure of the gift because the asset no longer exists in the estate), which under New Zealand law following the Wills Act 2007 produces no benefit to the intended beneficiary unless the codicil specifically addresses the substitution.

When a testator who made a will before entering a de facto relationship, civil union, or marriage wishes to confirm that their partner receives an adequate share of the estate — noting that under s. 18 of the Wills Act 2007, marriage, civil union, or de facto relationship does not automatically revoke an existing New Zealand will (unlike the previous law) — a codicil adding the partner as a beneficiary provides the necessary protection without voiding the entire existing estate plan.

When the testator wishes to add or remove a guardian appointment for minor children following a change in family circumstances — such as the death of the originally appointed guardian, an estrangement, or the guardian relocating overseas — a codicil updates the appointment under s. 27 of the Wills Act 2007. Guardianship provisions in wills are administered by the Family Court under the Care of Children Act 2004.

When a testator holds Maori land (whenua Maori) and wishes to confirm or amend the disposition of those interests, specialist legal advice from a practitioner with experience in the Maori Land Court and the Te Ture Whenua Maori Act 1993 is required before executing a codicil, as succession to Maori land interests is governed by separate statutory rules administered by the Maori Land Court.

A New Zealand Codicil to Will governed by the Wills Act 2007 must include the following components to be formally valid, admissible to probate by the High Court of New Zealand, and effective in amending the original will.

Testator identification must state the full legal name, date of birth, and residential address of the person making the codicil. Where the testator is known by multiple names (including a previous married name or a Maori name in addition to an English name), all known names should be listed to avoid identification disputes at probate.

Reference to the original will must precisely identify the will being amended by stating the date it was executed and, if known, the location where the original is stored (for example, with the testator's solicitor, held personally, or deposited with the Public Trust). The codicil should state the full name under which the will was executed.

Amendment clauses must identify each provision being changed with specificity. A codicil that states only "I amend clause 5 of my will" without quoting the provision creates ambiguity if the original will has been superseded by a previous codicil. Each amendment should follow the pattern: cite the clause reference in the original will, state that the clause is revoked, and substitute the new provision in full.

Executor changes must expressly revoke the previous appointment and name the new executor with their full legal name, residential address, and relationship to the testator. Under the Administration Act 1969, the High Court requires proof that the named executor was willing to accept the grant of probate — having a signed acceptance from the executor before executing the codicil is strongly advisable.

Confirmation of original will must state in unambiguous terms that the original will (and any previous codicils) remain in full force and effect except to the extent expressly amended by the current codicil. Without this clause, the codicil may be read as impliedly revoking broader provisions.

Execution formalities under s. 11 of the Wills Act 2007 require the testator to sign the codicil at the end (or direct another to sign in their presence if physically unable), in the simultaneous presence of two adult witnesses, with both witnesses signing in the testator's presence. Neither witness should be a beneficiary, a trustee, or a spouse or partner of a beneficiary — violation does not invalidate the codicil but causes the gift to that witness or their partner to lapse.

The forms-legal.com New Zealand Codicil to Will template includes s. 11 Wills Act 2007-compliant execution blocks, a testamentary capacity declaration, and a confirmation-of-will clause aligned with High Court probate application requirements under the High Court Rules 2016 Part 19.

Witness attestation blocks must include each witness's full name, occupation, and residential address. The High Court Registrar examines witness details on probate application to confirm compliance with the Wills Act 2007 execution requirements.
