New Zealand Tax and Superannuation for Retirees in Thailand

Reviewed by Greg Berryman, 7 September 2026

Retiring to Thailand as a New Zealander involves three separate questions: your NZ tax residency, your NZ Superannuation position, and your visa. All three work differently to the Australian equivalents covered elsewhere on this site.

NZ tax residency: two tests, either one catches you

You're a NZ tax resident if you meet either of these:

  • The 183-day test: present in New Zealand for more than 183 days in any rolling 12-month period, not a calendar year. Partial days count as full days, and residency backdates to the first of those days.
  • The permanent place of abode (PPOA) test: you have a home available to live in in New Zealand, assessed on your actual ties and habitual connection, not just ownership.

Ceasing residency is harder than starting it. You need to be absent from New Zealand for more than 325 days in a 12-month period, and have no permanent place of abode at any point during that absence. Keep a family home available and day count alone won't get you out.

Once you're a genuine non-resident, New Zealand taxes you only on NZ-sourced income. Residents are taxed on worldwide income.

NZ Superannuation works differently to the Australian Age Pension

NZ Super is universal, not income or asset tested. Anyone who meets the age and residence rules gets it, regardless of savings or other income.

  • You need 10 years of NZ residence from age 20, including 5 years after age 50. This requirement is gradually rising to 20 years by 2042 for people turning 65 from 1 July 2024 onward, so check where you sit on the transition.
  • You must be ordinarily resident and present in New Zealand, and already entitled to NZ Super, before you leave the country. Apply and then travel overseas before it's granted, and you risk the same kind of rejection covered on the Australian Age Pension claim page, for the same underlying reason.

Getting it paid to you in Thailand

New Zealand has social security agreements with a handful of countries, including Australia, Canada, and the UK. Thailand isn't one of them, and it's not covered by the separate Pacific portability arrangement either. That puts a Thailand-based retiree on general portability, where the payment is calculated at 1/45th of the full rate for every year you lived in New Zealand between ages 20 and 65, up to the full rate at 45 years.

You need to apply to Work and Income's International Services before you leave if you'll be overseas more than 26 weeks.

The tax treatment is the real difference from Australia

This is where NZ Super and the Australian Age Pension diverge sharply. NZ Super is taxable income while you're a New Zealand resident. But once you're genuinely residing overseas and receiving it as a portable payment, it's exempt from New Zealand income tax under section CW 28 of the Income Tax Act 2007. The policy reasoning is that your country of residence, not New Zealand, should have taxing rights once New Zealand is no longer providing you with public services.

Compare that to Australia, where the Age Pension becomes more heavily taxed once you're a non-resident, not less. Whether Thailand then taxes the payment once it's remitted there is a separate question, covered on the Thailand tax overview page.

The visa angle

New Zealand isn't on the list of nationalities eligible for Thailand's O-X long-stay visa, unlike Australia, the UK, the US, and Canada. New Zealanders looking at a long-term stay generally look at the DTV or the LTR visa instead. All five routes are compared on the visa options page.

Not tax or pension advice

NZ Super residence and portability rules have detailed conditions beyond what's covered here, and the transitional residence increase affects people differently depending on birth date. Talk to Work and Income's International Services and a tax professional before you finalise a move.
