Australian Working in NZ Tax: What Australians Need to Know

Published: 3 October 2026
Last updated: 3 October 2026

If you’re an Australian working in New Zealand, your tax obligations can depend on where you work, how long you stay, who employs you, where you are tax resident and whether you continue earning income from Australia.

Australian working in NZ tax can become particularly important when you move from Australia to New Zealand, work for a New Zealand employer, work temporarily in New Zealand for an Australian employer, or have income and assets in both countries.

This guide explains the key New Zealand tax rules Australians working in NZ should understand, including PAYE, tax residency, the 183-day rules, Australian income, double tax agreements and common compliance issues.

Quick Answer: Do Australians Working in NZ Pay New Zealand Tax?

Generally, Australians earning income from work performed in New Zealand may have New Zealand tax obligations. If you’re employed by a New Zealand employer, PAYE is generally deducted from your salary or wages.

If you remain an Australian tax resident and work temporarily in New Zealand, the Australia-New Zealand tax treaty may affect where your employment income is taxed. The treaty’s employment-income rules include an important 183-day test, but additional conditions must also be satisfied.

Your New Zealand tax residency is a separate question. Under New Zealand’s domestic rules, you can become a NZ tax resident if you are in New Zealand for more than 183 days in any 12-month period or if you have a permanent place of abode in New Zealand.

Australian Working in NZ Tax

Australians working in New Zealand may have New Zealand tax obligations on income earned from work performed in NZ.
New Zealand employees generally have PAYE deducted from salary or wages.
Tax residency is different from immigration or visa status.
New Zealand’s domestic 183-day tax-residency rule is different from the Australia-New Zealand tax treaty’s 183-day employment exemption.
The treaty exemption for employment income has additional conditions relating to the employer and where the employment cost is deducted.
New Zealand tax residents generally have New Zealand tax obligations on worldwide income, subject to applicable rules and double tax agreements.
Australians working temporarily in New Zealand should review both their Australian and New Zealand tax positions.

What Is Australian Working in NZ Tax?

Australian working in NZ tax refers to the New Zealand tax considerations that can apply when an Australian citizen or Australian tax resident performs work in New Zealand.

The correct treatment depends on your individual circumstances. Important factors can include:

how long you are physically present in New Zealand
whether you become a New Zealand tax resident
whether you work for a New Zealand or Australian employer
where your employment is physically performed
whether you continue receiving Australian income
whether you own property or investments in either country
whether the Australia-New Zealand tax treaty applies to your circumstances
whether you are an employee, contractor or business owner

Because these factors can overlap, Australians working across the Tasman should not assume that their Australian tax position automatically determines their New Zealand tax position.

7 Essential Australian Working in NZ Tax Rules

1. Working in New Zealand Can Create NZ Tax Obligations

If you earn income from working in New Zealand, you may need to pay New Zealand tax on that income.

For salary and wages, New Zealand employers generally deduct PAYE from payments to employees. PAYE covers income tax and the ACC earners’ levy.

You’ll generally need an IRD number and the appropriate tax code when working in New Zealand.

IRD states that employees provide their IRD number and tax code to their employer, and the employer deducts PAYE from salary or wages.

2. NZ Tax Residency Is Different From Your Visa or Immigration Status

Your immigration status determines whether you can stay and work in New Zealand. Your tax residency determines how New Zealand tax rules apply to you.

Under New Zealand’s domestic tax-residency rules, you can become a New Zealand tax resident when either:

you have been in New Zealand for more than 183 days in any 12-month period, unless a specific exception applies; or
you have a permanent place of abode in New Zealand.

The 183 days do not have to be consecutive. Parts of days in New Zealand can also count as days present.

If you become resident under the 183-day test, the residency is generally backdated to the first of those 183 days.

For Australians moving to Auckland, Wellington, Christchurch or another NZ location for work, the permanent-place-of-abode test can also be relevant even if the 183-day threshold has not yet been reached.

3. PAYE Usually Applies to NZ Employment Income

If you are employed by a New Zealand employer, your employer generally deducts PAYE from your salary or wages before paying you.

PAYE includes income tax and the ACC earners’ levy.

You normally provide your employer with:

your IRD number
your tax code information

If the correct information is not provided, a higher tax rate may apply.

If your only income is New Zealand employment income and the correct tax code has been used, you will often not need to file an individual tax return. However, additional income or other circumstances can change this.

4. The Treaty 183-Day Rule Is Not the Same as NZ Tax Residency

This is one of the most important points for Australian working in NZ tax.

People often assume that spending fewer than 183 days in New Zealand automatically means they do not pay NZ tax. That is not necessarily correct.

The Australia-New Zealand tax treaty contains an employment-income rule under Article 15. In certain circumstances, employment income can remain taxable only in the employee’s country of residence when the employee is present in the other country for no more than 183 days during the relevant 12-month period.

However, the treaty rule has additional conditions. Generally, the exemption requires consideration of:

whether you are present in New Zealand for no more than 183 days in the relevant 12-month period
whether your employer is a resident of Australia rather than New Zealand
whether the remuneration is not deductible by a New Zealand permanent establishment or fixed base of the employer
whether the remuneration is subject to tax in your country of residence

Therefore, simply counting your days in New Zealand is not enough to determine the final tax outcome.

5. Australian Income Can Still Matter After You Move to NZ

If you become a New Zealand tax resident, your Australian income may need to be considered as part of your wider New Zealand tax position.

New Zealand tax residents generally pay tax in New Zealand on worldwide income, subject to specific rules and any applicable double tax agreement.

This can become relevant if you continue to receive:

Australian salary or employment income
Australian rental income
Australian investment income
interest
dividends
business income
other overseas income

Foreign tax credits or treaty provisions may help address double taxation where the same income is taxed in both countries.

6. Australian and NZ Tax Residency Can Create Cross-Border Issues

It is possible for an individual to have tax-residency considerations in both Australia and New Zealand.

When both countries regard you as a tax resident, the relevant double tax agreement can become important.

The Australia-New Zealand tax treaty contains rules that can help determine how particular types of income are treated and how double taxation may be relieved.

This means Australians moving to New Zealand should review their residency position rather than assuming that moving countries automatically ends their Australian tax obligations.

7. Contractors and Self-Employed Australians Have Different Considerations

Not every Australian working in NZ is an employee.

If you operate as a contractor or are self-employed, your tax obligations can differ from those of an employee receiving PAYE.

Depending on your circumstances, you may need to consider:

how your income is calculated
deductible business expenses
GST registration
ACC levies
provisional tax
income-tax filing requirements
whether you have an Australian business or entity
whether cross-border business activities create additional tax obligations

Do not assume that an Australian contractor can simply invoice a NZ client without reviewing the New Zealand tax consequences.

Australian Working in NZ Tax: What Happens If You Work in Auckland?

If you move from Sydney or Melbourne to Auckland for a NZ job, your circumstances can change significantly.

For example, imagine an Australian employee moves to Auckland and starts working for a New Zealand company.

The key questions would include:

When did the person arrive in New Zealand?
Where is their permanent home?
Did they become a NZ tax resident?
Who is their employer?
Where is the employment physically performed?
Do they continue receiving Australian income?
Do they retain Australian property or investments?
What does the Australia-New Zealand tax treaty provide for their circumstances?

The answers determine the appropriate tax treatment rather than nationality alone.

Australian Working in NZ Tax Example

Example: An Australian professional moves from Sydney to Auckland to work for a New Zealand company.

The employee receives NZ salary and has PAYE deducted by the employer. They also continue receiving rental income from an Australian investment property.

The employee may need to consider:

NZ tax on their employment income
their NZ tax-residency position
how their Australian rental income is treated
Australian tax obligations
foreign tax credits
the Australia-New Zealand tax treaty
the timing of their move and change in residency

This is an illustrative example only. The actual tax outcome depends on the individual’s circumstances.

What If You Work in NZ for an Australian Employer?

This situation requires particular care.

An Australian employee who temporarily performs work in New Zealand may have a different tax position from someone who permanently moves to New Zealand and joins a NZ employer.

The Australia-New Zealand tax treaty may be relevant to employment income, particularly where the employee remains an Australian resident and the treaty’s conditions are satisfied.

However, the treaty’s 183-day employment rule contains multiple conditions. The employer’s residence, where the employment cost is deducted and the employee’s tax position in Australia can all matter.

Before assuming that your Australian employer means you only pay Australian tax, it is sensible to review the full cross-border position.

What If You Work Remotely From New Zealand for an Australian Company?

Working remotely from New Zealand for an Australian company can create additional tax considerations.

The fact that your employer is Australian does not automatically determine where your employment income is taxable.

You may need to consider:

where you physically perform your employment
your NZ tax residency
your Australian tax residency
the Australia-New Zealand tax treaty
PAYE obligations
your employer’s New Zealand obligations
any permanent-establishment or business considerations

Remote working arrangements should therefore be reviewed before you move rather than after a tax issue has arisen.

Do Australians Working in NZ Need an IRD Number?

If you are earning income in New Zealand, you will generally need an IRD number so that the correct tax can be deducted and reported.

Your employer will generally need your IRD number and tax-code information to calculate PAYE correctly.

If you do not provide the required information, a higher no-notification tax rate may apply.

Do Australians Working in NZ Pay ACC?

Employees receiving salary or wages generally have the ACC earners’ levy included in PAYE deductions.

The ACC earners’ levy is separate from income tax and the rate can change between tax years.

If you are self-employed or operating as a contractor, different ACC obligations can apply.

What Happens to Your Australian Property When You Work in NZ?

Moving to New Zealand does not automatically remove your Australian property from your tax considerations.

If you own an Australian investment property, you may continue to have Australian tax obligations on rental income.

If you become a New Zealand tax resident, the Australian rental income may also need to be considered under New Zealand’s worldwide-income rules, subject to applicable rules and the Australia-New Zealand tax treaty.

This is one reason why Australians moving to Auckland, Wellington or elsewhere in New Zealand should review their complete cross-border tax position.

What Happens to Australian Investments When You Move to NZ?

Australian shares, managed funds and other overseas investments can create additional New Zealand tax considerations after becoming a NZ tax resident.

Depending on the type and value of your investments, New Zealand’s foreign investment fund rules or other tax rules may become relevant.

Before moving, consider documenting your investment holdings, acquisition dates, values and income.

Common Australian Working in NZ Tax Mistakes

Assuming 183 Days Automatically Means No NZ Tax

The treaty’s 183-day employment exemption has additional conditions. It should not be confused with New Zealand’s domestic tax-residency test.

Ignoring Permanent Place of Abode

You can become a NZ tax resident through the permanent-place-of-abode test even when the 183-day test has not been met.

Assuming Australian Citizenship Determines Tax

Citizenship and tax residency are different concepts. Your tax obligations depend on your circumstances and the relevant tax rules.

Forgetting Australian Income

Moving to NZ does not necessarily end your Australian income or Australian tax obligations.

Not Reviewing the Employer Structure

Working for a NZ employer, Australian employer, overseas company or your own business can produce different tax considerations.

Waiting Until Year-End

Cross-border tax issues are easier to address when residency, employment arrangements and overseas assets are reviewed before or soon after a move.

Australian Working in NZ Tax Checklist

Before or soon after starting work in New Zealand, consider this checklist:

☐ Apply for an NZ IRD number if required
☐ Confirm your NZ tax code
