How to Choose an Accountant in NZ (and What Drives Cost)

By the Find an Accountant NZ team · Facts checked against the sources listed below on 18 October 2026.

The problem: you know you need help, but not who to ask

Usually something specific prompts the search: a GST registration, your first provisional tax bill, a rental property, a new company, or a letter from IRD. Then you find dozens of firms, all calling themselves accountants, with prices that are hard to compare. This guide explains the different titles, what each kind of professional can do, what drives the cost, and what to ask before you sign. To browse firms, start at the Hamilton Accountants directory.

Chartered accountant, accountant, bookkeeper or tax agent?

Chartered Accountant (CA). A member of Chartered Accountants Australia and New Zealand (CA ANZ), bound by the NZICA Rules and Code of Ethics and by its professional standards. Under section 14 of the New Zealand Institute of Chartered Accountants Act 1996, it is an offence to describe yourself in writing as a chartered accountant, or to use initials such as CA, unless the Institute's rules allow it. The maximum fine is $5,000. You can search for members, including those with a Certificate of Public Practice who have opted in to be listed, in the CA ANZ Find a CA directory.
Accountant. Section 14 names 'chartered accountant', the CA initials and 'registered accountant'. It does not reserve the plain word 'accountant', although it is still an offence to use wording that suggests membership you do not hold. A firm that calls itself an accountant may be very experienced, but the title alone tells you nothing about membership, so ask.
CPA. CPA Australia members can apply for a New Zealand public practice certificate. CPA Australia requires members who offer public accounting services to hold professional indemnity insurance.
Bookkeeper. A bookkeeper keeps your day-to-day records and may prepare GST returns. business.govt.nz suggests a bookkeeper can be a good option for day-to-day finances.
Tax agent. A tax agent is registered with IRD as an intermediary and links to clients in myIR. The main practical benefit is the extension of time. Returns are normally due by 7 July, but a tax agent's clients can be given until 31 March of the next year. End-of-year tax is then due 7 April instead of 7 February. Tax agent status is a separate registration with IRD, so ask whether a firm has it.

When is it time to get an accountant?

business.govt.nz suggests getting advice when you are starting out, growing, seeking investment, taking on large loans, closing or selling, struggling to pay bills, or dealing with tricky tax issues. In practice, the common triggers are:

reaching the $60,000 GST threshold (see our GST guide)
your first provisional tax bill (see our provisional tax guide)
buying a rental or starting short-stay letting (see our rental property tax guide)
incorporating a company or bringing in a partner (see our business structure guide)

What do accountants cost?

We do not publish price figures, because we have no authoritative source for typical NZ fees, and any average would say little about your situation. What drives the cost is more predictable:

Structure: a sole trader's IR3 is simpler than a company with an IR4, financial statements and shareholder salaries, or a look-through company with several owners.
Volume and quality of records: how many transactions there are, and whether your software is kept reconciled.
GST and payroll: how often returns are filed, and whether the firm prepares them or only reviews yours.
Rentals: the number of properties, depreciation schedules, ring-fenced losses and mixed-use calculations.
One-off events: a restructure, property sale, IRD review or catch-up on overdue returns.

Ask whether the firm charges by the hour, a fixed annual fee or a monthly package, and what each covers, such as compliance work, advice and software. Ask for an estimate before you book. business.govt.nz notes that many advisers offer a free first meeting. If you own a rental, IRD lists accountant's fees for the accounts, returns and advice as a deductible rental expense. For a business, ask your accountant how their fees are treated.

Questions to ask before you sign

Who will actually do my work, and are they a CA or CPA?
Is the fee fixed, and what exactly is included and excluded?
Which software do you support (for example Xero or MYOB), and will you set it up?
Are you a registered tax agent, and will I get an extension of time?
How quickly do you usually reply to emails, and who do I contact?
Do you work with businesses or landlords like me?

Also ask what happens when something unexpected comes up, such as an IRD letter or a big purchase. Is that covered by the fixed fee, or charged separately, and at what rate? A clear answer now saves arguments later. If you are moving from another accountant, ask how your records and the tax agent link will be transferred.

Your accountant may ask to see ID. business.govt.nz explains this is to meet anti-money laundering rules.

The engagement letter

CA ANZ members in public practice in New Zealand must follow PS-3 Terms of Engagement, which has applied since 1 January 2024. They must document and agree the terms of engagement with you, including the fee basis and billing arrangements, before the work starts. Later changes must be agreed in writing, and the terms must be reviewed regularly. The terms must also cover professional obligations, confidentiality, ownership of documents, and the firm's complaints policy. Read the letter. If the scope is vague, ask for it to be tightened before you sign.

When to get an accountant and how to choose one

The best time is before a deadline, not after. Shortlist two or three firms that work with clients like you. Check their membership in the CA ANZ directory, or ask for evidence of CPA public practice certification. Ask each for a fixed quote and a copy of their terms of engagement, and compare what is included rather than just the headline price. Browse and compare firms on the Hamilton Accountants directory, or go straight to tax accountants, rental property accountants, small business accountants or bookkeeping and payroll.

Common questions

Is 'accountant' a protected title in NZ?

Section 14 of the New Zealand Institute of Chartered Accountants Act 1996 protects 'chartered accountant', the CA initials and 'registered accountant', and bans wording that implies membership you do not hold. It does not reserve the plain word 'accountant', so check membership.

What is the benefit of using a tax agent?

A tax agent's clients can be given extra time to file their income tax return, as late as 31 March of the next year, instead of 7 July, and end-of-year tax is then due 7 April rather than 7 February.

How much does an accountant cost in NZ?

It depends on your structure, the volume and state of your records, GST and payroll, rentals and one-off events. Ask for a fixed quote and a written engagement letter that sets out the fee basis.

What should an engagement letter include?

For CA ANZ members in public practice, PS-3 requires agreed terms covering the fee basis and billing, professional obligations, confidentiality, ownership of documents and the firm's complaints policy.
