Do New Zealand Financial Advisers Owe You a Fiduciary Duty?

In most cases, no. New Zealand law does not define a fiduciary duty for financial advisers as a blanket statutory obligation.

But this is not the gap it might appear to be. The Financial Markets Conduct Act 2013 (FMC Act) and the Code of Professional Conduct for Financial Advice Services impose enforceable client-first duties on anyone giving regulated financial advice to retail clients. These obligations overlap substantially with fiduciary principles, even though they come from statute rather than equity.

For New Zealand investors, the practical question is whether an adviser's licence, business model, and culture reliably produce client-first advice. This article explains what the term fiduciary actually means, what legal protections exist here, and what checks matter more than any single word.

What "fiduciary" means in law

In common law, a fiduciary relationship arises when one party places particular trust and confidence in another, who then accepts a duty to act in the first party's interests above their own. Courts have recognised fiduciary duties between trustees and beneficiaries, directors and companies, solicitors and clients, and certain other categories. Whether a financial adviser in New Zealand owes a fiduciary duty to a client is a question of legal fact, determined by the nature of the relationship, the level of trust involved, and the representations the adviser has made. It is not something you can declare on a website and have it become true.

In the United States, the term carries specific regulatory weight. Registered Investment Advisers are legally required to act as fiduciaries under the Investment Advisers Act of 1940, and the distinction between fiduciary and non-fiduciary advice has significant practical consequences for American consumers. Much of the online content about fiduciary duty originates from this US context, which can create confusion for New Zealand readers researching the topic.

What protections exist in New Zealand

New Zealand has a robust legal and regulatory framework governing financial advice. It may not use the word "fiduciary," but the substance is strong. Under Subpart 5A of Part 6 of the FMC Act, anyone giving regulated financial advice must comply with the Code of Professional Conduct, which was updated in November 2025 and is enforced by the Financial Markets Authority (FMA).

The Code sets nine enforceable standards. The first five cover ethical behaviour, conduct, and client care: treat clients fairly, act with integrity, give advice suited to the client's circumstances, ensure the client understands the advice, and protect client information. The remaining four cover competence, qualifications, and continuing professional development. Breaches can result in FMA enforcement action, and the framework sits alongside broader consumer protections including the Financial Service Providers Register, mandatory dispute resolution schemes, and licensing requirements for all Financial Advice Providers.

The title "Financial Adviser" is itself a regulated term. You cannot legally use it in New Zealand unless you are registered on the Financial Service Providers Register and engaged by a licensed Financial Advice Provider (FAP). This is a meaningful distinction, because the term "fiduciary" has no equivalent protection. It is unregulated. A "finfluencer" could use it in a social media bio. There is no regulatory body checking whether anyone using the word has the qualifications, licence, or conduct standards to justify it.

Some NZ advisory firms do use "fiduciary" in their client-facing materials, and in some cases this commitment is backed by third-party certification such as CEFEX (the Centre for Fiduciary Excellence). These firms are making a genuine, auditable pledge. The regulatory gap we are pointing out is about the absence of any gatekeeper preventing less scrupulous operators from borrowing the same language.

What to actually look for when choosing an adviser

Rather than relying on a single word, it is more useful to assess whether your adviser's business model genuinely aligns their interests with yours. Several practical checks matter more than any label.

How is the adviser paid? Commission-based advisers can provide excellent advice, but the payment model creates potential conflicts. Fee-based and fee-only models reduce these conflicts, though no structure eliminates them entirely. Ask your adviser to explain, in plain language, every way they earn money from the relationship. If the answer is unclear or evasive, treat it as a signal.

What is the scope of their licence? New Zealand distinguishes between a FAP licence, which covers personalised financial advice, and a Discretionary Investment Management Service (DIMS) licence, which authorises the Financial Advice Provider to make investment decisions on your behalf. Many advisory relationships are advice-only, where the client retains full control over decisions, even though client-first duties still apply. A DIMS licence involves a higher level of regulatory scrutiny because the adviser exercises discretion over client funds. In our view, the obligations on a DIMS provider reflect many of the behaviours people associate with a fiduciary standard: acting in the client's best interest, with the authority and accountability to match. This reflects the nature of discretionary authority, not a judgement about adviser quality. DIMS is not the right model for every client, and a well-structured advisory relationship can serve investors just as effectively.

Is the firm owned by a product provider? Some of New Zealand's largest advisory firms are majority owned by banks or insurance companies. Ownership structures influence the range of products an adviser can recommend and the conflicts built into the advice. Ask directly: does any bank, insurer, or fund manager hold an ownership stake in this firm?

Can you see the conflicts register? Every licensed FAP is required to manage conflicts of interest. Ask your adviser whether you can review how these conflicts are identified and handled. The willingness to have this conversation is itself informative.

Does the adviser have a genuine client-first culture? This is harder to assess from the outside, but arguably the most important factor. At Become Wealth, our internal standard is straightforward. As CEO Joseph Darby puts it: "We give the same advice we would give a family member." This principle is formalised in our internal advice review process, where every recommendation is peer-reviewed before it reaches the client. Regulation sets the floor. Culture determines how far above it a firm operates, and no compliance framework can legislate for the judgement calls an adviser makes every day.

The question worth asking

The word "fiduciary" is a useful concept, but in New Zealand it functions as a description of conduct rather than a regulated credential. The Code of Professional Conduct already requires advisers to act with integrity, give suitable advice, and manage conflicts. These are enforceable obligations with real consequences. The gap in New Zealand is the absence of any control over who gets to use a specific word.

Most people choosing a financial adviser do not ask about licence type, ownership structure, or how conflicts are managed. These questions matter more than whether the adviser's website includes the word "fiduciary." If your adviser cannot clearly answer them, it is reasonable to reconsider whether the arrangement truly serves your interests.
