At 50, you’re 15 years from the KiwiSaver qualifying age of 65. This is the decade where fund type decisions get more complex — you still need growth, but you also need to start thinking about sequence-of-returns risk as retirement approaches. Here’s how to approach it.
The Short Answer
Balanced is appropriate for most 50-year-olds — but growth is still defensible. Some case for staying in growth until 55–57, then gradually shifting to balanced and conservative. Conservative at 50 is too cautious unless retirement is very close or risk tolerance is very low.
The 15-Year Horizon
15 years is still a meaningful investment period. Over 15 years, a growth fund has historically outperformed balanced — but the margin narrows compared to 25–35 year horizons, and the risk of a poorly-timed crash (just before retirement) starts to matter more.
Illustrative returns over 15 years (starting $80,000, $70k salary, 4% + 3%):
| Fund type | Approx. return | Balance at 65 |
|---|---|---|
| Conservative | 3.5% | ~$230,000 |
| Balanced | 5.5% | ~$290,000 |
| Growth | 7.5% | ~$360,000 |
Illustrative only. Does not account for salary growth, tax, or fee variation.
The gap between balanced and growth over 15 years is around $70,000 — still significant, but smaller than at 30 or 40. The question is whether that extra expected return is worth the risk of a poorly-timed crash.
Sequence-of-Returns Risk
At 50, a new risk starts to matter: sequence-of-returns risk — the danger that a major market crash happens in the 3–5 years before you need to withdraw.
If you’re in a 100% growth fund at 64 and markets fall 30%, your balance drops significantly just as you’re about to retire. Unlike at 30, you have much less time for a full recovery before you need the funds.
This is why conventional guidance is to gradually de-risk from growth to balanced in your 50s, and from balanced to conservative in your early 60s — not all at once, but progressively.
Recommended Glide Path from 50 to 65
| Age | Recommended fund |
|---|---|
| 50–55 | Growth or balanced |
| 55–58 | Balanced |
| 58–61 | Balanced to moderate |
| 61–63 | Moderate or conservative |
| 63–65 | Conservative |
| 65+ | Conservative or income (drawdown phase) |
This is a guideline, not a rule. Your personal circumstances — other assets, income in retirement, risk tolerance — all affect the right answer.
What If You’re Behind at 50?
If your balance at 50 is lower than you’d like, staying in growth for longer may make sense. The FMA and IRD report average KiwiSaver balances of roughly $65,000–$95,000 for 50-year-olds in 2025. If you’re significantly below this, a more aggressive approach is warranted.
Why staying in growth makes sense when you’re behind:
- Conservative or balanced locks in lower expected returns at exactly the time you need to close a gap
- 15 years in growth rather than balanced could add $70,000+ to your balance
- The risk of a crash exists, but it also exists in balanced funds (just to a lesser degree)
Catch-up strategies at 50:
- Increase contribution rate to 8% or 10%
- Make voluntary lump-sum contributions (bonus, sale of assets, inheritance)
- Maximise the MTC each year — $521.43 is a guaranteed 50% return on those contributions
- Review whether a voluntary contribution before 30 June each year reaches the $1,042.86 threshold
The KiwiSaver in your 50s guide covers each of these catch-up strategies in detail.
PIR Rate Review at 50
At 50, with a larger balance than at 30, overpaying PIR tax has a more significant impact. Your PIR is set on your KiwiSaver income from the two prior tax years — if you’ve had a lower-income year recently, you may qualify for a reduced rate.
| Annual taxable income | PIR |
|---|---|
| Up to $14,000 | 10.5% |
| $14,001–$48,000 | 17.5% |
| Over $48,000 | 28% |
At $100,000 KiwiSaver balance earning 6%, overpaying at 28% vs 17.5% costs roughly $630/year in excess tax — worth correcting via the PIR rate update process.
Lifecycle Fund Option at 50
Lifecycle KiwiSaver funds automatically shift your allocation from growth to conservative as you age — removing the manual decision-making. At 50, some lifecycle funds will already be transitioning toward balanced.
Pros at 50:
- Set-and-forget — no need to monitor and manually switch
- Avoids the emotional trap of switching at the wrong time
Cons:
- Often higher fees than DIY passive growth/balanced options
- The automatic glide path may not match your specific situation (e.g., early retirement, large other assets)
How different providers structure their lifecycle KiwiSaver funds — including glide paths and fees — varies significantly.
Two Scenarios for 50-Year-Olds
Scenario A: On track, comfortable balance Linda, 50, earning $95,000. KiwiSaver balance $90,000. Contributing 6%.
- Fund: Balanced now; plan to move to conservative around 62–63
- On track for a solid retirement balance; don’t need to take on extra risk
- Review provider fees — at $90,000+ balance, the fee difference between 0.3% and 1% costs $630/year
Scenario B: Underfunded, needs to maximise returns Mark, 50, earning $70,000. KiwiSaver balance $28,000. Had several years on savings suspension.
- Fund: Growth — needs the higher expected return to close the gap
- Increase to 10% contribution rate or make significant voluntary contributions
- Cannot afford to be conservative at 50; the cost of lower returns outweighs the sequence risk at this balance
- Plan to review fund type at 58–60 when the balance is healthier
Provider Choice at 50
At 50, with 15 years to retirement, fees still matter — but you may also start valuing providers with clear drawdown tools and retirement planning features.
| Provider | Balanced fund fee | Notes |
|---|---|---|
| Simplicity | ~0.29% + $30/yr | Low-fee passive; good for set-and-forget |
| Kernel | ~0.25% + $60/yr flat | Very competitive at higher balances |
| Milford | ~0.85% | Active balanced; historically strong |
| Booster | ~0.50% | Mid-range fee; solid fund range; good retirement tools |
| ANZ | ~0.93% | Bank convenience; higher fees |
