Term Deposits and Interest Rates in 2026: Where to Park Cash

You've spent decades building your retirement savings. Now, a big chunk sits in cash or term deposits, and you're trying to figure out: where exactly should this money live?

It's a practical question without a simple answer. Interest rates in New Zealand have shifted dramatically over the past few years. The Official Cash Rate (OCR) has moved up and down, and term deposit rates have followed. In 2026, retirees holding cash are navigating a landscape where yesterday's 5.5% rate might be today's 4.2%, or vice versa.

This article focuses on the near-term cash bucket, the money you'll need in the next 1-3 years to cover living expenses, emergencies, or planned spending. For this portion of your retirement savings, safety and accessibility matter more than chasing higher returns. But that doesn't mean you should ignore where and how you park it.

A term deposit (sometimes called a fixed deposit) is a straightforward product: you place a lump sum with a bank for a fixed period, from as short as one month to as long as five years. In exchange, the bank pays you a guaranteed interest rate.

The appeal for retirees is obvious. Your capital is protected (within the deposit protection scheme covering up to $100,000 per depositor per bank), you know exactly what you'll earn, and there's no market volatility to worry about. If you lock in a 12-month term deposit at 4.5%, you'll receive 4.5% when it matures, regardless of what happens to interest rates in the meantime.

But here's the trade-off: your money is locked away. Break a term deposit early, and most banks will penalise you with reduced or zero interest. This makes term deposits less suitable for emergency funds and better suited for money you know you won't need until a specific date.

In 2026, term deposit rates vary significantly by bank and term length. Rates for six-month deposits might differ from one-year or two-year terms, sometimes by half a percentage point or more. Smaller banks and credit unions occasionally offer higher rates to attract deposits, while the major banks may offer convenience and brand familiarity at slightly lower returns.

Many retirees assume interest rates follow a predictable pattern. They don't. The Reserve Bank of New Zealand sets the OCR based on inflation, employment, and broader economic conditions. When inflation rises, the RBNZ typically raises the OCR to cool spending. When the economy slows, they lower it to encourage borrowing and investment.

Term deposit rates roughly track the OCR, but with a lag and a margin. Banks adjust their deposit rates based on their own funding needs, competition, and expectations about where the OCR is heading. This means the 5% rate you saw last year could drop to 3.8% this year if the RBNZ cuts rates, or it could climb if inflation concerns return.

The important lesson: past returns are not indicative of future returns. If you locked in a great rate two years ago, congratulations. But when that term deposit matures in 2026, you'll be re-investing at whatever the current rate happens to be. And if rates have fallen, your income from that cash will drop accordingly.

This variability is why many retirees using the bucket strategy for retirement income ladder their term deposits, a strategy we'll cover shortly.

Term deposits aren't your only option for parking cash. Here's how the main alternatives stack up:

High-Interest Savings Accounts
These accounts offer variable interest rates and full flexibility. You can withdraw money anytime without penalty. However, the rates are typically lower than term deposits, often 0.5% to 1% less. Some banks offer bonus rates for the first few months or if you meet certain conditions (like making regular deposits or not withdrawing funds).

High-interest savings accounts work well for emergency funds or money you might need on short notice. But for cash you know you won't touch for six months or a year, term deposits usually offer better returns.

Notice Saver Accounts
These accounts sit between savings accounts and term deposits. You earn a higher interest rate than a standard savings account, but you must give notice (commonly 31, 60, or 90 days) before withdrawing. If you can plan ahead, notice savers can offer competitive rates with more flexibility than term deposits.

Cash Funds and Cash PIEs
Some managed funds invest exclusively in short-term, low-risk assets like bank bills and government bonds. These are technically investments rather than deposits, so they're not covered by deposit protection. However, they offer daily liquidity and can sometimes match or slightly exceed term deposit rates after fees. Interest earned in PIE funds is taxed at your Prescribed Investor Rate (PIR), which may be lower than your marginal tax rate.

For retirees, the key question is: how soon will I need this money? The answer determines whether flexibility or a locked-in rate matters more.

Instead of locking all your cash into a single term deposit, many retirees spread it across multiple deposits with staggered maturity dates. This is called laddering.

Here's how it works in practice: imagine you have $150,000 set aside for near-term expenses. Rather than putting it all in a single 12-month term deposit, you might split it into three $50,000 deposits maturing in 6 months, 12 months, and 18 months.

The benefits are twofold. First, you're not locked out of all your cash at once. If interest rates rise, you'll have money coming free regularly to reinvest at the new, higher rates. Second, if rates fall, at least some of your cash is still earning the older, better rate for a bit longer.

Laddering also helps with sequence of returns risk in a different way, it reduces the impact of unfortunate timing. If you happen to need cash right when rates have dropped, you're only re-investing part of your portfolio at the lower rate, not all of it.

There's no perfect ladder structure. Some retirees use three-month intervals, others prefer six or twelve. The key is matching maturity dates to when you'll actually need the funds.

Every dollar of interest you earn from term deposits or savings accounts is taxable income. The bank will deduct Resident Withholding Tax (RWT) before paying you, typically at 10.5%, 17.5%, 30%, or 33%, depending on the rate you've nominated with your bank.

It's important to set your RWT rate correctly. If you're retired and living on NZ Super plus modest investment income, your actual marginal tax rate might be lower than the default 33% RWT many banks apply. Choosing the correct lower rate means you keep more of your interest upfront, rather than waiting for a refund when you file your tax return.

For interest earned in PIE funds (like cash PIE funds), tax is calculated using your PIR, which can be 10.5%, 17.5%, or 28%. If your total taxable income is modest, this can result in a lower effective tax rate compared to interest taxed at your marginal rate.

This isn't advice to switch products based solely on tax treatment, but it's a factor worth understanding when comparing your options. A 4.2% term deposit taxed at 17.5% RWT nets you more than a 4.2% term deposit taxed at 33%, even though the headline rate is identical.

Not all term deposits are created equal. Here are the practical details that matter:

• Minimum deposit requirements: Some higher rates are only available if you deposit $10,000, $25,000, or even $50,000. Check the threshold before assuming you qualify.
• Interest payment frequency: Do you want interest paid monthly, quarterly, annually, or at maturity? Monthly payments provide regular income but may compound less than interest paid at maturity. Some retirees prefer monthly payments to supplement NZ Super; others reinvest interest to maximise compounding.
• Early withdrawal penalties: Most banks allow early withdrawal in hardship situations, but the penalty varies. Some reduce your interest rate to the equivalent savings account rate; others forfeit interest entirely. Read the terms before locking in.
• Rollover options: When your term deposit matures, does it automatically roll over into a new term at the prevailing rate, or do you need to give instructions? Automatic rollover is convenient but can lock you into a less competitive rate if you're not paying attention.
• Promotional vs ongoing rates: Some banks advertise headline rates for new customers only, or for the first few months. Make sure you understand what the rate will be for the full term you're considering.

Comparison websites like interest.co.nz publish updated term deposit rates across all major New Zealand banks, which can save you hours of research.

It's worth stepping back and asking: how much should you hold in term deposits and cash in the first place?

The answer depends on your broader retirement strategy. If you're using a bucket approach, your near-term bucket (covering 1-3 years of expenses) might sit entirely in cash and term deposits. This insulates you from market downturns and gives you the freedom to let your growth assets recover without being forced to sell at a bad time.

If you're drawing down retirement savings, you might keep 2-3 years' worth of living expenses in cash to avoid selling shares or KiwiSaver units during a market dip. For context, if you need $60,000 per year beyond NZ Super, that's $120,000 to $180,000 in cash or term deposits.

But holding too much in cash has a cost: inflation. Even if you're earning 4% on a term deposit, inflation at 3% means your real return is only 1%. Over time, keeping excess cash can erode your purchasing power. This is why many retirees balance cash for near-term needs with investments in shares or managed funds for longer-term growth.

The key trade-off is between certainty and growth. Cash gives you certainty. Shares and managed funds offer the potential for higher returns but come with volatility. The right mix depends on your time horizon, risk tolerance, and income needs, topics worth discussing with a licensed financial adviser.

Misconception 1: Term deposits are completely risk-free.
While term deposits are low-risk and covered by the deposit protection scheme (up to $100,000 per depositor per institution), they're not entirely without risk. If a bank were to fail and your deposits exceeded the protected limit, you could face losses. Additionally, inflation risk is real: if your term deposit earns 4% and inflation runs at 4%, your purchasing power hasn't grown at all.

Misconception 2: Longer terms always mean higher rates.
Not necessarily. In some interest rate environments, shorter-term deposits offer better rates than longer ones, a situation called an inverted yield curve. In 2026, it's worth comparing rates across all term lengths rather than assuming longer is always better.

Misconception 3: You're locked in no matter what.
While term deposits do restrict access, most banks allow early withdrawal in cases of genuine hardship (like serious illness or financial distress). You'll face penalties, but it's not as absolute as some retirees assume. Always check the specific terms with your bank.

Misconception 4: All banks offer the same rates.
Rates vary significantly. In early 2026, the spread between the highest and lowest 12-month term deposit rates across major banks can be 0.5% or more. On a $100,000 deposit, that's $500 per year, not an amount to ignore.
