Lifestages KiwiSaver Funds NZ 2026: Should Your Fund Get Safer Automatically?

Lifestages (age-based) KiwiSaver funds de-risk you automatically as you get older. Here is when that discipline helps, when it quietly costs you growth, and how it stacks up against an advised review.

A lifestages KiwiSaver fund makes one promise: as you get older, it quietly moves your money from growth assets like shares into safer assets like cash and bonds, without you lifting a finger. It is a tidy idea. For some savers it is genuinely the right call. For others it shaves real money off their retirement by selling growth they never needed to give up.

This guide explains exactly how an age-based glide path works in New Zealand, names the actual fund that runs one, shows the dollar gap with worked numbers, and sets out when automatic de-risking is your friend and when it is not.

TL;DR: A lifestages (age-based) KiwiSaver fund automatically de-risks you as you age, gliding from roughly 85% growth assets up to age 49 down to 30% growth by 65+. That discipline suits hands-off savers, but de-risking on age alone can lock in a Conservative fund's 4.1% p.a. ten-year return when Growth averaged 7.8% p.a. — a costly gap if you are not spending the money at 65.

What is a lifestages (age-based) KiwiSaver fund?

A lifestages fund is a single KiwiSaver investment option that changes its own asset mix based on your age. You join once and never pick a fund type. The provider does it for you: aggressive while you are young, then progressively more conservative as you approach 65.

This is different from how most of KiwiSaver actually works. The government default option is one Balanced fund (35–63% growth assets), delivered by 6 appointed default providers — it is not an age-based glide path ⁶. So if you were auto-enrolled and never chose, you are likely sitting in a static Balanced fund that does not de-risk at all. Automatic de-risking only happens if you deliberately choose a lifestages-style option, or if you (or an adviser) move you yourself.

In New Zealand the headline example is the Lifestages KiwiSaver Scheme, issued and managed by Funds Administration New Zealand Limited (FANZ), a wholly owned subsidiary of SBS Bank, and now marketed as the SBS Wealth KiwiSaver Scheme. Its Lifestages Auto option is the age-based glide path. The scheme also offers four core funds you can pick by hand — Cash, Income, Focused Growth and High Growth — with management fees from 0.45% to 0.81% p.a., no membership, joining, exit, switch or performance fees.

For context on who this is built for: there are still 341,453 default KiwiSaver members in New Zealand — people who were auto-placed and never actively chose anything ⁵. Age-based options exist precisely to give that group a sensible path without forcing a decision they will never make.

How does a glide path de-risk you over time?

A "glide path" is just the schedule of how your growth-asset share falls as you age. Lifestages Auto uses five age buckets. Here is the actual allocation and look-through annual fund fee at each step ¹²:

†The 85% growth / 15% income split is SBS's stated strategic weighting of the underlying funds (85% High Growth, 15% Focused Growth). On Sorted's look-through basis the 0–49 bucket reads closer to ~98% growth / ~2% income, because the underlying "Focused Growth" sleeve is itself growth-heavy ¹².

The mechanics matter. At 65+ the option holds only ~30% in growth assets and roughly 70% in income and cash. In FMA projection language, your statement assumption steps down the whole ladder over time — Defensive 1.5%, Conservative 2.5%, Balanced 3.5%, Growth 4.5%, Aggressive 5.5% p.a. (all after fees and 28% tax) ³. A glide path walks you down that ladder year by year, trading expected return for less short-term volatility.

That trade is the entire question. Less volatility is valuable when you are about to spend the money. It is expensive when you are not.

The upside: hands-off and disciplined

Two real benefits, and they are not trivial.

1. It removes the most common KiwiSaver mistake: doing nothing. Most Kiwis never review their fund type once in their lives. A glide path means the most basic risk adjustment — easing off shares as retirement nears — happens automatically. For the 341,453 default members ⁵ and anyone who knows they will never log in to switch, that automation beats good intentions.

2. It enforces de-risking before you actually need the cash. If you genuinely plan to draw most of your balance at 65 — a house deposit top-up, a lump-sum lifestyle change, clearing the mortgage — you do not want to be 90% in shares the year a market falls 30%. Sequencing risk (a bad market right as you start withdrawing) is one of the few genuinely dangerous moments in a KiwiSaver journey, and a glide path manages it without you having to time anything.

The discipline is the product. You are paying for a decision to be made on schedule rather than never.

The downside: it doesn't know your real plans

A glide path knows one fact about you: your date of birth. It does not know whether you will spend your balance at 65 or leave most of it invested for another 25 years. And that single blind spot is where it can cost real money.

Why is de-risking on age alone a problem?

Most New Zealanders do not cash out their KiwiSaver at 65. They keep working, draw NZ Super, and leave the bulk of the balance invested — effectively a 25- to 30-year time horizon past "retirement". For that saver, being shifted to ~30% growth at 65+ is too conservative by a wide margin. They are giving up decades of compounding to avoid volatility they will never feel, because they are not selling.

How big is the return gap between Conservative and Growth?

Here is the gap in plain returns. Over the ten years to mid-2025, Morningstar's KiwiSaver survey put the average annual return (net of fees, before tax) at:

That is a 3.7 percentage point annual gap between Conservative and Growth, and 4.5 points to Aggressive — every year, compounding. On a $200,000 balance, the difference between 4.1% and 7.8% is roughly $7,400 in the first year alone, before compounding makes it worse.

Worked example: the cost of de-risking on age, not plans

Scenario: Margaret turns 65 in 2026 with $250,000 in KiwiSaver. She is still working part-time, draws NZ Super, and does not plan to touch her KiwiSaver for at least 15 years. A glide path moves her to a 30%-growth mix; an adviser might keep her closer to Balanced or Growth because her real horizon is 80, not 65.

*Illustrative, using the stated 10-year category averages held flat, before tax and future contributions. Past returns are not a guide to the future.

Margaret's "safety" cost her roughly $310,000 of growth over a horizon where she was never going to sell into a downturn anyway. The glide path did its job — it just optimised for the wrong date. Want to test this on your own balance and timeline? Try our KiwiSaver growth calculator.

When does automatic de-risking actually help you?

It helps when your real spending date lines up with the glide path's assumption. In practice, that means:

• You genuinely plan to withdraw most of your balance at or near 65 — a lump sum, mortgage payoff, or major lifestyle purchase.
• You will never review or switch funds yourself, so "automatic and roughly right" beats "static and possibly wrong".
• Short-term volatility would force you to sell at the worst time — for example, a small balance you are about to draw on for a first home or retirement transition.
• You have no other liquid savings buffer, so a 30% market fall the year you retire would be genuinely damaging.

If two or three of those describe you, a lifestages option is doing exactly what it should.

When does it cost you growth you didn't need to give up?

It costs you when the glide path de-risks faster than your actual need for the money:

• You will keep most of your KiwiSaver invested well past 65 (the common NZ reality). Your true horizon is 80+, not 65, so a ~30%-growth mix is far too cautious.
• You have other income and assets — NZ Super, rental income, a paid-off home — so your KiwiSaver does not need to be "safe", it needs to grow.
• You are decades from retirement but the option already caps you at 85% growth when a pure High Growth or Aggressive fund could run higher. Over the ten years to mid-2025, the gap between the Conservative (4.1%) and Aggressive (8.6%) category averages was 4.5 percentage points a year ⁴ — wide, and it compounds.
• Fees are not trivial. Lifestages Auto's youngest bucket charges 1.17% p.a. ¹²; Simplicity's Growth fund, Kernel's and SuperLife's index options sit far lower. On a long horizon, fee drag and over-conservatism stack.

A common pattern: people in their late 60s whose KiwiSaver has been de-risked to Conservative, with no plan to spend it for another 20 years. The automation worked as designed, but it can quietly cost tens of thousands in forgone growth.

Lifestages vs choosing and reviewing with an adviser

Both manage risk as you age. The difference is what they use to decide.

In short, a glide path is built for the average 65-year-old, while an advised review is built for your situation — including the common case that you will not touch the money for another two decades. An adviser can compare funds across every major NZ provider rather than one in-house option, and a yearly KiwiSaver review adjusts your mix to your real plans, not just your date of birth.

A quick note on the 2026 settings that change the maths

De-risking decisions sit on top of contribution settings that just changed. Worth keeping straight while you decide:

• The maximum government contribution halved at Budget 2025 from 50c to 25c per $1; it is now $260.72 ⁷, and you need to contribute $1,042.86 between 1 July and 30 June to get the full amount ⁸. Earn over $180,000 taxable and you get nothing ⁹.
• The default employee and matching employer rate rises to 3.5% each (7% combined) from 1 April 2026, heading to 4% in 2028 ¹⁰.
• Check your PIR: 10.5% (income to $15,600), 17.5% (to $53,500), or 28% above that ¹¹. The wrong PIR quietly erodes returns no glide path can recover.

Your lifestages checklist

01. Find out if you are even on a glide path. Most default members are in a static Balanced fund, not an age-based option ⁶. Check your provider and fund name.

02. Pin down your real spending date. Will you draw the money at 65, or leave it invested to 80+? This single answer drives everything.

03. Compare the return gap. Conservative averaged 4.1% vs Growth 7.8% over ten years ⁴ — decide whether that gap is worth giving up for your horizon.

04. Check the fee. 1.17% p.a. on the Lifestages Auto youngest bucket ¹² — compare against Simplicity, Kernel and SuperLife.

05. Confirm your PIR and contribution rate so the basics are not leaking returns. Our KiwiSaver health check flags both in a couple of minutes.

06. Book a review to align de-risking with your plans, not just your age.

Frequently asked questions

Is a lifestages KiwiSaver fund a good idea? For a hands-off saver who genuinely plans to spend their balance around 65, yes — it automates the most-skipped decision in KiwiSaver. For the more common Kiwi who leaves most of the money invested past 65, de-risking on age can cost significant growth, because it shifts you to roughly 30% growth assets at 65+ when your real horizon is 80+.

What is the difference between a lifestages fund and the KiwiSaver default? The default is a single Balanced fund (35–63% growth) run by 6 appointed providers — it does not change with your age ⁶. A lifestages option is an age-based glide path that de-risks automatically. If you were auto-enrolled and never chose, you are almost certainly in the static default, not a glide path.

Who runs lifestages funds in New Zealand? The best-known is the Lifestages KiwiSaver Scheme, issued by FANZ (a subsidiary of SBS Bank) and now marketed as the SBS Wealth KiwiSaver Scheme. Its Lifestages Auto option is the age-based glide path; the scheme also offers Cash, Income, Focused Growth and High Growth funds you can pick yourself.

How much growth could automatic de-risking cost me? It depends on your horizon. Over the ten years to mid-2025, Conservative funds averaged 4.1% p.a. and Growth funds 7.8% p.a. ⁴. On a $250,000 balance left invested 15 years, that gap is illustratively worth over $300,000 — money given up to avoid volatility you may never need to sell into.

Should my KiwiSaver get safer as I get older? Some de-risking near a genuine spending date makes sense to manage sequencing risk. But "older" is not the same as "about to spend it". The right trigger is your real withdrawal timeline, not a birthday — which is exactly what an advised review uses and a pure glide path cannot.

Can an adviser do what a glide path does, but better? Yes — an annual review de-risks you the same way but uses your plans, other assets and spending date, and compares funds across every major NZ provider rather than one scheme. The trade-off is that you have to actually book the review; the glide path needs nothing from you.
