Ireland and New Zealand have a bilateral Social Security Agreement that has been in force since 1994. Unlike the EU coordination framework that covers European countries, this is a direct bilateral treaty negotiated specifically between the two countries. If you have worked in both New Zealand and Ireland, the agreement means your contribution periods in each country can be combined to help you qualify for pensions in both — but the interaction between the two systems contains one significant gotcha that catches many returning Irish workers by surprise.

Understanding the dollar-for-dollar offset rule before you retire is essential. Proper planning around it can make a material difference to your combined retirement income.

New Zealand Superannuation (NZ Super): How It Works

NZ Super is New Zealand’s state pension. Like the Danish Folkepension, it is a universal, flat-rate, residence-based payment — it is not calculated based on how much you earned or how many years you paid contributions. Every eligible New Zealand resident receives the same weekly rate regardless of their earnings history. This makes NZ Super conceptually very different from the Irish State Pension (Contributory), which is earned through PRSI contributions.

Qualifying for NZ Super

To receive NZ Super you must:

The 10-year residency requirement is where the Ireland-New Zealand Social Security Agreement comes in. Under the agreement, Irish PRSI contribution periods can be counted toward the 10-year New Zealand residency test. This is significant for Irish people who spent fewer than 10 years in New Zealand — Irish years can make up the shortfall and allow you to qualify for at least a partial NZ Super.

Important distinction: Irish PRSI years can help you qualify for NZ Super (meeting the 10-year threshold), but they do not increase the amount you receive. NZ Super is a flat rate — there is no pro-rata calculation based on years. Either you qualify and receive the full weekly rate, or you do not qualify at all. (The agreement allows qualification with fewer New Zealand years, not a scaled amount.)

NZ Super Rate (2026)

NZ Super rates are adjusted twice yearly in line with average wages and the Consumer Price Index. As of April 2026, the approximate weekly rates after tax (at the standard 'M' tax code) are:

Recipient Type Weekly Rate (NZD, approx.) Annual (NZD, approx.)
Single, living alone NZD 520 NZD 27,040
Married/partnered (each) NZD 400 NZD 20,800

At current exchange rates (approximately NZD 1 = €0.55), the single-person rate is roughly €14,870 per year. However, these amounts are before the offset rule described below is applied.

The Dollar-for-Dollar Offset: The Critical Gotcha

NZ Super is means-tested against overseas pensions. Under the Ireland-New Zealand agreement, any Irish State Pension you receive is deducted directly from your NZ Super entitlement using the direct deduction method. The deduction is applied at the exchange rate at the time of assessment.

In plain terms: if you receive an Irish State Pension of €14,420 per year (approximately NZD 26,000 at current rates), New Zealand will reduce your NZ Super by NZD 26,000. For many dual recipients, this means the NZ Super payment is very small or effectively zero — the two pensions effectively substitute for rather than add to each other.

This is the most important planning point for Irish-NZ dual pensioners. Without advance planning, you may find that your Irish State Pension almost entirely offsets your NZ Super, leaving you no better off than if you had only one pension. A regulated advisor familiar with both systems can help you model the most advantageous sequence of drawing each pension, taking into account timing, residence, exchange rate risk, and tax in both countries.

Residence Requirement for NZ Super

NZ Super is also residence-dependent. If you return to Ireland permanently and no longer live in New Zealand, NZ Super stops. It is not paid abroad to people who have left New Zealand — unlike the Irish State Pension, which is portable worldwide. This means an Irish person who spent time in New Zealand but has returned home permanently can only claim NZ Super if they move back to New Zealand in retirement, or spend sufficient time there as an ordinarily resident person. This is a fundamental difference between NZ Super and European state pensions.

KiwiSaver: New Zealand’s Workplace Savings Scheme

KiwiSaver is New Zealand’s voluntary workplace savings scheme, introduced in 2007. It is not a state pension — it is a privately-managed fund similar in spirit to Irish personal pensions or AVCs. Key features:

If you worked in New Zealand and were enrolled in KiwiSaver, your account will have been accumulating contributions. The money is held by a KiwiSaver provider (ANZ, ASB, Fisher Funds, Simplicity, Milford, etc.). Once you turn 65, you can access the funds regardless of where you live — KiwiSaver can be accessed from Ireland.

There is also a KiwiSaver emigration withdrawal option: if you permanently emigrate from New Zealand to a country other than Australia, you can apply to withdraw your KiwiSaver balance (minus any Crown contributions). However, this terminates your KiwiSaver membership. Whether to withdraw early or wait until 65 is a decision that depends on your tax situation, investment returns, and retirement plans — and is worth discussing with an advisor.

The Irish State Pension: What Your NZ Years Do

For the Irish State Pension (Contributory), you need a minimum of 520 PRSI paid contributions (10 years). Under the Ireland-New Zealand agreement, New Zealand contribution periods can be counted toward this threshold if your Irish years alone fall short. The Irish DSP applies the agreement when you submit your pension application and declare your New Zealand work history.

Note that New Zealand periods only help you qualify for the Irish pension — they do not increase the Irish payment amount, which is calculated solely on actual PRSI contributions.

Worked Example: 12 Years in New Zealand, 28 Years Irish PRSI

Consider an Irish person who emigrated to Auckland at 25, worked there for 12 years (age 25–37), was enrolled in KiwiSaver throughout, then returned to Ireland and paid 28 years of PRSI before retiring at 67.

Pension Position Amount (approx.)
Irish State Pension (Contributory) 28 PRSI years; meets 520-contribution threshold; NZ years not needed for qualification. Receives full pension. €14,420/year
NZ Super (if living in NZ) 12 NZ years (since age 20) + Irish years via agreement = qualifies. But Irish pension of approx. NZD 26,200 deducted via direct deduction. NZ Super single rate approx. NZD 27,040 − NZD 26,200 = NZD 840 net NZD 840/year (€462) net
KiwiSaver 12 years of contributions (employee + 3% employer); accessible at 65 wherever you live Depends on salary, fund growth; check provider

The worked example illustrates the stark effect of the offset rule. The person in this scenario is effectively no better off from NZ Super because the Irish pension almost exactly offsets it. KiwiSaver savings are the main additional benefit from the New Zealand years. If the same person had only 8 Irish PRSI years (not meeting 520 on their own), they would also need the New Zealand years to qualify for a reduced Irish pension — a very different calculation.

Applying for NZ Super and Irish State Pension

Applying for NZ Super

Applications for NZ Super are made to Work and Income New Zealand (WINZ) at workandincome.govt.nz. You can apply online or by post. Apply at least 2–3 months before you turn 65. You will need to declare any overseas pensions you are receiving or entitled to receive, as WINZ will apply the offset calculation. If you are living in Ireland and do not ordinarily reside in New Zealand, you are generally not entitled to NZ Super — you must be resident in New Zealand to receive it.

Applying for Irish State Pension

Apply for the Irish State Pension via the DSP at MyWelfare.ie or by postal application. Declare your New Zealand work history on the application form. The DSP will contact New Zealand’s social security authority to verify your NZ contribution periods under the bilateral agreement.

Notify both authorities of foreign pensions. When you receive your Irish pension, notify Work and Income NZ so they can apply the offset correctly. Failure to do so can result in overpayments that must be repaid. Similarly, if your Irish pension amount changes (e.g. budget increases), the NZ offset should be adjusted accordingly.

Tax on NZ Pension in Ireland

Ireland and New Zealand have a Double Taxation Agreement. As an Irish tax resident, NZ Super and KiwiSaver drawdown income are taxable in Ireland as foreign income. You declare them on your annual Irish tax return. Any New Zealand tax already withheld can typically be credited against your Irish liability. Currency fluctuations (NZD/EUR) can affect your effective income year to year, which is worth factoring into retirement income planning.

Key Steps for Irish Returnees

  1. Locate your KiwiSaver account. If you are unsure which provider holds it, contact Inland Revenue New Zealand (ird.govt.nz) who maintains the KiwiSaver register.
  2. Check your NZ Super eligibility. Calculate your New Zealand residency years since age 20. If you fall short of 10 years, check whether Irish PRSI periods under the agreement make up the difference.
  3. Model the offset impact. Before assuming you will receive two full pensions, calculate how much of your NZ Super will be offset by your Irish pension. A financial advisor can run this scenario for you.
  4. Decide on KiwiSaver withdrawal strategy. Do you wait until 65 for maximum accumulation, or withdraw on emigration? Get advice before deciding.
  5. Check your Irish PRSI record at MyWelfare.ie. Apply for Irish State Pension via DSP, disclosing your NZ work history.
  6. Apply for NZ Super via WINZ if you will be resident in New Zealand at retirement.
  7. Plan for Irish tax on all foreign pension income.
