Trusts Act 2026 Trustee Duties for NZ Families
A trustee can make a sensible decision about a family home, a loan or a beneficiary payment and still leave the trust exposed if nobody records it. That is why people searching for Trusts Act 2026 trustee duties are usually looking for more than a legal definition. They want to know what must actually be done, who needs to do it, and how to show it was done.
For New Zealand family trusts, the governing law is the Trusts Act 2019. There is no separate Trusts Act 2026. The duties below are the duties trustees need to keep managing in 2026 under the 2019 Act, alongside the terms of their own trust deed. If your trust is governed by Australian law, get Australian legal advice instead - trust rules differ by state and territory.
What trustee duties look like in everyday life
Being a trustee is not simply having your name on a deed or signing forms when your solicitor sends them through. Trustees hold and manage trust property for the people entitled to benefit under the trust. That role brings legal duties, and it requires trustees to act together unless the deed says otherwise.
The Trusts Act 2019 sets out mandatory duties that generally cannot be removed by a trust deed. In plain English, trustees must know the terms of the trust, act in line with those terms, act honestly and in good faith, use their powers for the proper purpose, and manage trust property for the benefit of beneficiaries.
This matters in ordinary family situations. Say a trust owns the family home and one trustee wants to let an adult child live there at a reduced rent. It may be a reasonable decision, but trustees should check the deed, consider all relevant beneficiaries, agree on the decision, and record why the arrangement is fair to the trust. A casual conversation at a barbecue is not a trust record.
Trustees must also avoid making an undisclosed profit from the role, unless the trust deed or informed consent properly permits it. If a trustee has a personal interest in a transaction, such as buying a trust asset or lending money to the trust, that needs careful handling and usually professional advice.
Trusts Act 2026 trustee duties: the practical checklist
The law can sound abstract until it is connected to the records on your desk, in your email inbox and in the filing cabinet. Start with the practical work below.
Know what the deed allows
Your trust deed is the operating document. It identifies the trustees and beneficiaries, sets out trustee powers, and may contain rules about appointing or removing trustees, distributing income, making loans, or holding a family home.
Keep the original deed and every deed of variation, resettlement, appointment and retirement together. Do not rely on an old scanned copy if you are unsure whether later changes exist. A missing variation can change who has authority to make a decision.
Some trustee duties under the Act are default duties, meaning the deed may change or exclude them. That is why a generic checklist is useful, but it cannot replace reading the actual deed.
Keep the trust’s property separate and identifiable
Trust assets should be clear. That includes real property, bank accounts, shares, vehicles, loans owed to the trust and any other significant assets. Trustees should be able to answer basic questions promptly: what does the trust own, what does it owe, and where is the evidence?
For a family home, retain ownership records, insurance information, rates notices and documents relating to borrowing. For loans, record the lender, borrower, balance, interest terms, repayments and any changes agreed. A handwritten note saying “family loan sorted” will rarely give trustees or their accountant enough to work with.
Keeping trust money separate from personal money is especially important. Paying a trust expense from a personal account may sometimes be fixable, but it should be recorded clearly and reimbursed or accounted for properly. Blurred finances make it harder to demonstrate that trustees have acted for the trust, rather than for themselves.
Make decisions together, then record them
A trustee decision does not need to be dramatic to need a record. Decisions about insurance, property repairs, loans, beneficiary distributions, changes of address, accountant appointments and trustee changes all affect the trust.
A useful resolution records the date, trustees present or consulted, the decision made, the reasons or relevant information considered, and each trustee’s approval. Attach key supporting material where relevant, such as a valuation, quote, loan statement or adviser’s letter.
The record is not paperwork for paperwork’s sake. It gives future trustees a clear account of what happened. It also helps when a bank, lawyer, accountant, beneficiary or insurer asks how authority was given.
Maintain the documents the Act expects trustees to hold
The Act requires trustees to keep core trust documents. These include the trust deed and later variations, records of trust property, records of liabilities, accounting records, trustee decisions, appointments and removals of trustees, and contracts or other documents necessary to understand the trust’s administration.
For a long-running family trust, gathering these documents can reveal gaps: a former trustee who was never formally removed, property sold years ago but still shown in old records, or annual accounts that stopped after the accountant changed. Finding a gap is useful. It gives you a specific task to resolve before the record becomes harder to reconstruct.
Give beneficiaries appropriate information
Trustees have information duties to beneficiaries under the Trusts Act 2019. The exact information to provide, and whether a request should be met, depends on the beneficiary, the deed and the circumstances. Trustees must consider requests properly rather than simply ignoring them.
This is an area where discretion matters. A beneficiary may be entitled to basic trust information, but not necessarily every document or every detail they ask for. Factors such as privacy, the nature of the beneficiary’s interest, the settlor’s intentions and the impact on other beneficiaries can be relevant. Seek legal advice before refusing a significant request or releasing sensitive information.
Review investments and financial commitments with care
Trustees have a duty to invest prudently unless the deed changes that position. For a typical family trust, this does not mean trustees must become investment experts. It does mean they should give real consideration to risk, return, diversification, liquidity, tax and the needs of beneficiaries before making or retaining investments.
The same care applies to guarantees, loans and major commitments. If the trust guarantees a family business debt or advances money to a beneficiary, trustees should understand the risk to the trust’s assets and document the basis for the decision. Where the issue is complex, get legal, accounting or financial advice before signing.
A simple annual routine prevents most record gaps
Trust administration is easier when it is not left until a property sale, a death, a relationship breakdown or a bank request forces action. An annual review creates a manageable rhythm.
Set aside time each year for all trustees to confirm the current trustee and beneficiary details, review assets and liabilities, check insurance, reconcile loans, file financial statements and tax material, consider whether any decisions need resolutions, and identify upcoming obligations. If the trust has income, make sure the IR6 return and related information are prepared by the required due date with your accountant.
Then update the record while the details are fresh. Add minutes, resolutions, statements and correspondence in one secure place, rather than leaving documents spread across personal emails, adviser portals and household drawers.
Trust Ready is designed for this practical part of the job: helping New Zealand trustees identify what needs attention, keep deeds and records together, create resolutions and minutes, and receive reminders before annual tasks slip past. It is administration support, not legal or accounting advice. Your lawyer and accountant remain the right people to call when the deed needs interpreting, a conflict arises, tax treatment is unclear, or a transaction is significant.
When a routine task needs professional advice
Some issues should not be solved with a template or an assumption. Speak with a lawyer before changing trustees, varying the deed, dealing with a beneficiary dispute, transferring property, making a major distribution, entering a related-party transaction, or responding to a serious beneficiary information request. Speak with an accountant about tax returns, beneficiary tax treatment, financial statements, debt forgiveness and loan balances.
The right question is not “Can we make this decision?” but “Do we have authority, have all trustees considered it properly, and can we show our work?” When your trust record answers those questions, looking after a family trust becomes a steady responsibility rather than a stressful scramble.
