NZ Super and Working: How Employment Affects Your Entitlement

At 65, you might be ready to slow down, but you're probably not ready to stop entirely. Maybe you love your work, need extra income, or simply want to stay engaged. The question that keeps many pre-retirees awake at night is this: will working reduce my NZ Super?

The short answer is wonderfully simple: no. New Zealand's universal superannuation system is genuinely universal. Whether you earn nothing or $200,000 a year, your NZ Super entitlement remains exactly the same. There's no income test, no means test, and no employment restrictions.

But here's where it gets interesting. While working doesn't reduce your entitlement, it absolutely affects your take-home pay through the tax system. Understanding this distinction could save you thousands of dollars and help you plan a more comfortable retirement.

If you've got friends or family in Australia, the UK, or the USA, you might have heard horror stories about pension clawbacks. In many countries, earning income in retirement means losing part of your government pension. Some systems reduce benefits dollar-for-dollar above certain thresholds. Others create complicated formulas that leave people confused about whether working is even worthwhile.

New Zealand took a different approach. NZ Super is a universal entitlement based on residency and age, not your work history or current income. According to Work and Income, you're entitled to NZ Super if you're 65 or older, a New Zealand citizen or permanent resident, and have lived in New Zealand for at least 10 years since age 20 (with at least five of those years since turning 50).

That's it. No calculations about how much you're earning. No forms declaring your income. No reduction if you decide to work three days a week or take on consulting projects.

As of 2024, a single person living alone receives $556.20 per week after tax, while a couple receives $842.48 combined (both amounts assume the M tax code). These amounts don't change whether you're working or not.

Here's the part that trips people up: while NZ Super isn't means-tested, it is taxable income. And when you combine NZ Super with employment income, your total taxable income can push you into higher tax brackets.

New Zealand's personal income tax rates for 2024-2025 are progressive:

• 10.5% on income up to $14,000
• 17.5% on income between $14,001 and $48,000
• 30% on income between $48,001 and $70,000
• 33% on income between $70,001 and $180,000
• 39% on income over $180,000

Let's look at a real example. Sarah is 66 and receives NZ Super of about $28,920 per year (gross, before tax). She also works part-time as a bookkeeper, earning $35,000 annually. Her total taxable income is $63,920.

Without the part-time work, Sarah's NZ Super would be taxed at the lower rates (10.5% and 17.5%). But with her combined income, she crosses into the 30% tax bracket for the portion above $48,000. The extra income is still valuable, but she needs to understand that she'll pay 30% tax on that top slice of income, not the 17.5% she might have expected.

When you start receiving NZ Super, Work and Income will ask you to choose a tax code. This is where many people make costly mistakes that result in surprise tax bills at year-end.

The most common tax code for NZ Super is M (or M SL if you have a student loan). This code assumes NZ Super is your only or main source of income and applies the standard progressive tax rates.

But what if you're also working? This is where it gets tricky. According to IRD guidance on tax codes, if you have two sources of income, you need to:

• Use the M tax code for your main source of income
• Use a secondary tax code (SB, S, ST, or SA) for your other income source

Here's the common mistake: many people keep the M tax code on their NZ Super and also have M on their employment income. This means both income sources are taxed as if they're your only income, starting from the lowest tax bracket. The result? You're undertaxed all year, and IRD sends you a bill after you file your annual return.

The solution is to use a secondary tax code on whichever income source is smaller. Secondary tax codes apply flat tax rates (ranging from 10.5% to 45%) without the tax-free threshold, ensuring you're taxed correctly on your combined income throughout the year.

Knowing that you can work doesn't automatically mean you should, or that working full-time makes financial sense. The beauty of having no income test is that you can be strategic about how much you work.

Consider part-time or contract work that keeps your total income below key tax thresholds. If your combined income stays under $70,000, you'll avoid the 33% tax bracket entirely. For many people, this sweet spot, combined with their NZ Super payments, provides a comfortable lifestyle without the stress of full-time employment.

Time your work strategically. Some retirees work intensively for part of the year (such as seasonal work or project-based consulting) and take the rest of the year off. This can be both personally rewarding and tax-efficient, depending on your total annual income.

Understand the ACC earner levy implications. If you're employed or self-employed, you'll pay ACC earner levies on your employment income (not on NZ Super). For 2024-2025, the ACC earner levy is 1.53% of your liable income. While this isn't a huge cost, it's worth factoring into your calculations when deciding how much to work.

Think beyond immediate income. Working in your late 60s and early 70s might mean you can delay withdrawing from your KiwiSaver or other retirement savings, allowing those funds to continue growing. This strategy can significantly increase your financial security in your late 70s and 80s when working is no longer an option.

While NZ Super itself has no income test, some other benefits and assistance programs do consider your income. This is important if you're relying on supplementary support.

Accommodation Supplement is income-tested. If you're receiving this additional support for housing costs, your combined income from NZ Super and employment may reduce or eliminate your entitlement.

Disability Allowance and other special assistance payments may also have income thresholds. If you're currently receiving these, check with Work and Income before taking on employment to understand how your payments might be affected.

SuperGold Card benefits are tied to NZ Super entitlement, not income. You keep your card and all its perks regardless of whether you work.

Rates rebates and other local council assistance programs often have income tests. If your combined income exceeds the threshold, you might lose eligibility for these cost-saving programs.

The lack of an income test means you have real flexibility in designing your retirement income strategy. Rather than thinking in binary terms (working or not working), you can create a customized approach that balances income, leisure time, and tax efficiency.

Some factors to consider in your planning include the health benefits of staying engaged in work, even part-time. Research consistently shows that people who remain active and socially connected in retirement report better physical and mental health outcomes. For many, work provides structure, purpose, and social interaction that are hard to replicate elsewhere.

There's also the reality that NZ Super alone may not fund the lifestyle you want, especially in expensive cities like Auckland or Wellington. Supplementing with even modest employment income can make the difference between budget anxiety and comfortable living.

The flexibility to reduce work gradually, rather than stopping abruptly at 65, can ease the psychological transition into retirement. Many people find that phasing out of work over several years, perhaps taking on fewer hours or responsibilities, creates a more satisfying retirement journey.

Myth: Working will reduce my NZ Super payment.
Reality: Your NZ Super entitlement never decreases based on other income. You receive the full amount regardless of employment earnings.

Myth: I don't need to worry about tax if I'm only working part-time.
Reality: All income is taxable. Even modest part-time earnings combined with NZ Super can create tax obligations, especially if you're using the wrong tax code.

Myth: I should wait until I stop working to apply for NZ Super.
Reality: There's no advantage to delaying your NZ Super application because you're working. Apply at 65 (or slightly before) to ensure payments start on time. Unlike some overseas systems, you cannot defer NZ Super to receive higher payments later.

Myth: My employer needs to know I'm receiving NZ Super.
Reality: Your NZ Super is between you and Work and Income. Your employer doesn't need to know, though you do need to ensure you're using the correct tax code for your employment income (likely a secondary code if NZ Super is your main income source).
