New Zealand Tax Residency Rules: The 183-Day Test
183-day threshold
How the 183-day rule works in New Zealand
New Zealand counts 183 days in any 12 month period. A 325 day test over 36 months also exists.
Rolling 12-month window. This means the count looks back from any given date, not just the calendar year boundary. A rolling window is harder to track manually because the number changes every day.
If you exceed 183 days, New Zealand may tax your worldwide income as a tax resident. The exact consequences depend on your personal situation, any applicable tax treaties, and the type of income involved.
How the count works
New Zealand applies two residency tests in parallel. The 183 day test catches you if you spend more than 183 days in New Zealand across any 12 month span, and residency runs from the first day you were present in that window. The permanent place of abode test sits alongside it and picks up anyone with an enduring connection to a New Zealand home, even without meeting the day count.
What counts as a day
Days are counted on physical presence, so any part of a day spent in New Zealand counts as a full day. The 12 month window rolls forward continuously rather than aligning to a tax year.
Beyond the day count
For many people, the permanent place of abode test is what actually triggers residency. Owning or renting a New Zealand home that is available to you, together with personal and economic ties to the country, can establish residency well below 183 days.
Special tax regimes
Newly arrived tax residents who have not been resident in the previous 10 years pick up transitional residence status. For up to four years from the date residency starts, most foreign source income (excluding certain employment income) is exempt from New Zealand tax.
Tax treaties
New Zealand treaties use the OECD tiebreaker. The 183 day rule reappears in the dependent personal services article, where it splits taxing rights between New Zealand and the worker's home country.
Frequently asked questions
How does the transitional resident rule help new arrivals?
If you have not been NZ tax resident in the previous 10 years, most foreign source income is exempt from New Zealand tax for up to four years from the date residency starts. Foreign employment income earned for work performed abroad is generally not covered by the exemption.
When does the 12 month window for the 183 day test start?
It rolls. If you spent 183 days in New Zealand across any 12 month span, you are resident from the first day of that span, not from the date IRD applies the test.
Can the permanent place of abode test override the day count?
Yes. Owning a furnished New Zealand home that you regularly use can establish residency even with relatively few days on the ground.
