New Zealand abolished death duties in 1979. There is no inheritance tax, no estate duty, no succession tax of any kind. For British nationals who arrive having spent years watching HMRC’s 40% charge accumulate against their worldwide estate, this is one of the genuinely attractive features of New Zealand life, and like Australia it applies cleanly: no regional variation, no family-member rate schedules, no equivalent to France’s 60% charge on non-family beneficiaries. An estate passing to adult children in New Zealand faces no New Zealand succession tax at all.
That is only part of the picture. New Zealand estates still pass through a probate process, the policy proceeds of any offshore investment structure need specific planning to reach beneficiaries efficiently, and, most importantly for British nationals, the UK’s 40% inheritance tax on worldwide assets continues to apply to those who remain UK-domiciled, regardless of how long they have lived in Wellington or Queenstown. Of those three issues, the probate process is manageable, the structure question is addressable, and the UK IHT tail requires specific action. Leaving it unaddressed is not a passive position.
New Zealand’s Succession Framework
With no inheritance or estate tax, the succession costs in New Zealand are limited to the process of estate administration rather than any tax on the transfer itself. New Zealand estates pass through probate (a court-supervised process under the Administration Act 1969, requiring a grant of probate before assets can be distributed). For a straightforward estate with a valid will, the process typically takes several months. During that period, New Zealand-held assets are frozen pending the grant, and beneficiaries must wait. A British expat who dies holding New Zealand bank accounts, New Zealand investments, and property in Auckland faces a probate process in New Zealand before any of those assets can move.
New Zealand is not an EU member state, so Brussels IV (the EU Succession Regulation that allows British nationals in France or Spain to elect UK succession law over local forced heirship rules) does not apply. New Zealand common law does not impose equivalent forced heirship provisions in the continental European sense, but the Family Protection Act 1955 allows certain family members and dependants to make a claim against an estate where adequate provision has not been made for them. This is relevant for British expats whose wills were drafted with UK succession principles in mind and whose New Zealand family circumstances have evolved since arriving.
UK Inheritance Tax Does Not Stop at the Tasman
For UK-domiciled British nationals, HMRC charges inheritance tax at 40% on the worldwide estate above the nil-rate band of £325,000. Domicile is not determined by where you live: most British nationals in New Zealand retain their UK domicile of origin unless they have formed a genuine and settled intention to remain in New Zealand permanently and can demonstrate it clearly. British professionals who arrived with family ties in the UK, who retain UK property or pension entitlements, or who have not yet obtained permanent residency in New Zealand have not, in most cases, formed the definitive settled intention that a change of domicile requires. HMRC’s assessment of domicile is conservative and the burden of proof falls on the individual.
The consequence is familiar to British expats across this series, from Singapore to Australia to Hong Kong: a British professional in Christchurch whose worldwide estate comprises a UK property, a UK pension pot, a New Zealand investment portfolio, and an offshore portfolio bond faces UK IHT at 40% on the combined value above £325,000 , regardless of New Zealand having no succession tax of its own. New Zealand imposes no charge, but HMRC imposes its full charge on the same worldwide assets. The two systems do not interact on the death tax itself: New Zealand simply does not have one.
From April 2025, the UK introduced a residency-based reform to IHT: once you have been non-UK resident for ten consecutive tax years, your non-UK assets begin to phase out of the UK IHT net. For British expats who have been in New Zealand long enough and consistently pass the HMRC Statutory Residence Test as non-UK resident, this creates a meaningful long-term planning horizon. The ten-year threshold is not a short timeline, however, and for those in the first decade of New Zealand life, UK IHT on worldwide assets remains fully in scope. Managing the SRT carefully in the meantime matters: British professionals in New Zealand who visit the UK frequently, retain UK property, or have other substantial UK connections must track their UK day count and tie position each tax year to confirm non-UK resident status.
The contrast with France is instructive. British expats in France face both French succession tax (up to 45% for children, 60% for non-family beneficiaries above a minimal allowance) and UK IHT simultaneously. That double exposure is one of the most complex succession problems in this entire series and requires careful structure to address both systems. In New Zealand, the local succession environment is entirely benign: no charge, no forced rate schedules, a common law probate system. The only substantial succession problem for most British expats in New Zealand is the UK IHT tail. The planning task is therefore more focused than in France, but no less important for those with worldwide estates above the nil-rate band.
The Named Beneficiary Mechanism
A portfolio bond (an international investment-linked insurance policy written out of a jurisdiction such as the Isle of Man or Guernsey) addresses both the New Zealand probate process for the policy value and the UK IHT exposure, through the same structural mechanism.
A portfolio bond is a life assurance contract. On death, the insurer pays the policy proceeds directly to the named beneficiaries without the funds passing through the estate. In New Zealand, this means the policy value bypasses the probate process entirely: beneficiaries receive the proceeds directly, without waiting for a court grant under the Administration Act. For a British professional in New Zealand whose estate includes a portfolio bond alongside New Zealand property and investments, the investment portfolio reaches beneficiaries while other assets follow the standard administration process. The liquidity available before probate completes can be practically significant, particularly where beneficiaries are UK-resident and not familiar with the New Zealand legal system.
On the death benefit and FIF rules: IRD’s April 2026 IR461 guide confirms explicitly that FIF income does not arise from a death benefit under a life insurance policy where the policy was entered into at a time when the person was non-resident and had not been a New Zealand tax resident for at least the previous ten years. A portfolio bond established before New Zealand residency (which is the recommended approach under the transitional resident planning window described in the companion post to this one) satisfies this condition. The death benefit is therefore exempt from FIF income, and the named beneficiary receives the full policy proceeds without an additional New Zealand tax charge at the point of claim.
Trust Structuring for UK IHT
For the UK IHT dimension, appropriate trust structuring around the policy can in many circumstances remove the policy value from the UK taxable estate. A portfolio bond held directly by a UK-domiciled policyholder forms part of their UK estate for HMRC’s assessment. Where the policy is written in trust (an offshore trust arrangement established outside the policyholder’s estate), the death benefit can fall outside the 40% UK IHT charge. This requires correct structuring from the outset: the trust instrument, the reservation of benefit rules, and the relationship between the trust, the policyholder, and the policy all need specialist legal attention. Retrospective structuring after a health diagnosis is rarely effective, and the reservation of benefit provisions are applied rigorously by HMRC.
A portfolio bond held in an appropriately structured offshore trust, with named beneficiaries, can therefore bypass New Zealand probate for the policy value, ensure the death benefit is received free of FIF tax by beneficiaries, and position that death benefit outside the UK taxable estate simultaneously. It is not a simple off-the-shelf solution, and it requires qualified legal and tax advice in both the New Zealand and UK contexts. But for British expats in New Zealand whose worldwide estates exceed the nil-rate band, it addresses the only succession tax problem they actually face.
Portability: A Practical Consideration
New Zealand is, for many British professionals, one stop in a longer international career. The pattern of British nationals spending several years in New Zealand before returning to the UK, moving to Australia, or relocating elsewhere is well established, particularly in healthcare, engineering, technology, and finance. A portfolio bond written from the Isle of Man or Guernsey travels with the policyholder through all of those moves. The named beneficiary designation and trust arrangement remain in force whether the policyholder subsequently moves to Australia, returns to London, or relocates to Singapore. The structure does not need to be unwound and rebuilt at each transition.
This portability is particularly relevant for British expats in New Zealand who have not yet formed a clear view of their long-term plans. A portfolio bond established during the New Zealand transitional resident window provides immediate structural benefit, continues to function efficiently if the policyholder moves on, and keeps the UK IHT planning framework intact regardless of where they are living when they eventually die. The decision about whether to remain in New Zealand does not need to be made before the bond is established.
For British professionals in New Zealand who have not reviewed their UK IHT position (particularly those whose worldwide estate including UK assets exceeds the nil-rate band), a portfolio bond in trust for the investment portfolio, alongside a valid New Zealand will covering local assets and a UK will covering UK-sited assets, provides a practical and portable framework. Providers such as RL360, Hansard, Friends Provident International (FPI), and Utmost International all write Isle of Man or Guernsey-based structures suitable for this purpose.
