KiwiSaver vs Term Deposit NZ — Which Is Better?

Updated

Term deposits are New Zealand’s most popular savings vehicle after KiwiSaver — safe, predictable, and offered by every major bank. But how do they stack up against KiwiSaver, and when does one beat the other?


The Core Difference

KiwiSaverTerm deposit
ReturnsVariable (market-linked for growth funds)Fixed rate for the term
RiskLow to high (depends on fund type)Near zero — government guarantee up to $100,000
Employer matchYes — 3%+No
Government MTCYes — up to $521.43/yrNo
LiquidityLocked until 65 (with exceptions)Locked for the term (break fees apply)
TaxPIE (max 28% PIR)Taxed at marginal income tax rate (up to 39%)
Inflation protectionGrowth funds typically beat inflationFixed rate may fall behind inflation
Access in emergencyVery limitedBreak fee, then full access

Where Term Deposits Win

Certainty

A term deposit pays a fixed, agreed interest rate for a set period. There’s no market risk. A 1-year term deposit at 4.5% will return exactly 4.5% regardless of what the NZX or global markets do.

For money you cannot afford to lose — emergency funds, house deposits being held for settlement, short-term savings goals — this certainty is genuinely valuable.

Liquidity (relative to KiwiSaver)

Term deposits are locked for the term, but break fees are manageable and you eventually get your money back. KiwiSaver is locked until 65 with very limited exceptions. For money you might need before retirement, a term deposit is far more accessible.

Low complexity

No fund type choice, no provider comparison, no PIR rates. Deposit, earn interest, done.


Where KiwiSaver Wins

The employer match is unbeatable

Your employer contributes at least 3% of gross salary — an immediate 100% return on your 3% contribution. A term deposit at any interest rate cannot match a guaranteed 100% return.

This alone makes KiwiSaver the priority for employed people up to the employer-match threshold.

The member tax credit

Contribute $1,042.86/year and receive $521.43 from IRD — a guaranteed 50% return on that amount. Again, no term deposit rate matches this.

PIE tax advantage for higher earners

KiwiSaver is a PIE fund. Returns are taxed at your PIR rate — a maximum of 28% even if your income tax rate is 33% or 39%.

Term deposit interest is taxed as ordinary income at your marginal rate. On a $100,000 term deposit at 4.5%, a 39% taxpayer pays $1,755 in tax. In a KiwiSaver balanced fund with equivalent yield, the tax is capped at 28% — saving $385 in tax on the same return.

The higher your income, the more the PIE advantage matters.

Long-run returns

Over 20–30 year periods, KiwiSaver growth funds have historically returned 7–9% annually — significantly more than term deposit rates, which have typically ranged from 2–6% depending on the interest rate environment.

A $50,000 investment over 25 years:

  • Term deposit at 4.5% average: ~$151,000
  • KiwiSaver growth at 7% average: ~$271,000

The gap is large — but growth funds carry market risk that term deposits don’t.


When to Use a Term Deposit vs KiwiSaver

Use a term deposit for:

  • Emergency fund — KiwiSaver can’t be accessed in most emergencies; term deposits can
  • Short-term savings goals (1–5 years) — house deposit top-up, car, travel
  • Capital you cannot risk losing — retirees drawing down, conservative investors who need certainty
  • Savings above the KiwiSaver lock-in level — once KiwiSaver is funded optimally, term deposits are a solid low-risk parking place for additional capital

Prioritise KiwiSaver (over term deposits) for:

  • Retirement savings — employer match + MTC + PIE tax + compounding make KiwiSaver superior for long-run retirement building
  • Long-term savings (15+ years) — market risk is manageable over long horizons; the return difference is substantial
  • Employed people under 65 — employer match is non-negotiable

Current NZ Term Deposit Rates (Mid-2026)

As at mid-2026, major NZ bank term deposit rates for 6–12 months are broadly in the 4.0%–5.0% range, having come down from the peaks of 2023–24. For comparison:

  • 6-month TD: ~4.0%–4.5%
  • 12-month TD: ~4.2%–5.0%
  • 2-year TD: ~4.0%–4.5%

These are before tax. After tax at 33%, a 5% TD yields ~3.35% net. A KiwiSaver balanced fund at 5% net return with PIR at 28% yields ~3.6%.

At current rates, the after-tax return gap between term deposits and conservative KiwiSaver funds is narrow — particularly for low-risk allocations. The employer match and MTC are what tip the scale decisively toward KiwiSaver.


KiwiSaver Cash and Conservative Funds vs Term Deposits

For members approaching retirement or in very conservative KiwiSaver funds:

  • KiwiSaver cash funds invest in bank deposits and cash equivalents — similar underlying assets to a term deposit
  • Returns are typically slightly below direct term deposit rates due to management fees
  • The PIE tax treatment and ease of management partially offset the fee drag

For retirees or near-retirees who want low-risk investment, a KiwiSaver conservative or cash fund and a mix of term deposits can work well together — KiwiSaver provides the tax-efficient wrapper; term deposits provide liquidity and certainty.


Frequently Asked Questions

Is KiwiSaver safer than a term deposit? In a KiwiSaver cash or conservative fund, the underlying assets are similar to a term deposit (bank deposits, bonds). For growth or aggressive funds, the risk is much higher than a term deposit. Term deposits up to $100,000 are covered by the NZ deposit guarantee scheme (DPGS), providing government backing. KiwiSaver does not have the same government guarantee on investment returns.

Can I have both KiwiSaver and a term deposit? Yes — and for many people, this is optimal. KiwiSaver for retirement savings (capturing employer match + MTC); term deposits for accessible savings, emergency fund, or short-to-medium term goals.

Should I break my term deposit to put money into KiwiSaver? Probably not — break fees apply, and you lose accrued interest. Let the term deposit mature, then decide where to direct the proceeds based on your current goals.

Do term deposits count toward the KiwiSaver MTC? No. The MTC is earned on contributions to your KiwiSaver account. Term deposits are a completely separate financial product and have no interaction with KiwiSaver.
