KiwiSaver Drawdown Strategy — How to Withdraw in Retirement

Updated

Accumulating KiwiSaver is only half the job. How you draw it down in retirement — the rate, the timing, and the fund you stay in — determines how long it lasts and how much income it generates. This guide walks through the key decisions.


When Can You Start Drawing Down?

KiwiSaver becomes fully accessible from the qualifying KiwiSaver age, currently 65. You do not have to withdraw at 65 — there’s no deadline. Your balance stays invested until you instruct your provider to pay it out.

See KiwiSaver at 65 — your options for the full withdrawal mechanics.


Three Drawdown Approaches

1. Lump sum withdrawal

Withdraw all or most of your balance at once. Pros: simplicity, flexibility. Cons: you lose the tax-advantaged PIE structure and must manage the money yourself (term deposits, shares, etc.) where returns may be lower and tax treatment less favourable.

Best suited to: paying off a remaining mortgage; major expenses (home modification, travel); members who want full control and have other income sources covering daily expenses.

2. Regular income drawdown

Leave the balance invested in KiwiSaver and set up automatic periodic payments to your bank account. Pros: balance continues growing (or generating returns) in a low-tax PIE structure; disciplined, systematic income. Cons: you must actively manage the drawdown rate.

This is the most common and generally recommended approach for most retirees.

Contact your KiwiSaver provider to set up regular payments. Most providers support weekly, fortnightly, or monthly withdrawals. Minimum withdrawal amounts vary by provider.

3. Ad hoc withdrawals

Draw money when you need it — no regular schedule. Pros: maximum flexibility; balance grows for as long as possible. Cons: requires more active management; risk of underspending or overspending.

Best suited to: retirees with other income sources (NZ Super covers essentials, KiwiSaver is a buffer for larger expenses).


How Much Can You Safely Withdraw Per Year?

The key question: at what rate can you withdraw without running out of money?

The 4% rule (adapted for NZ)

The “4% rule” originated in US research suggesting a 4% annual withdrawal from a balanced portfolio has a high probability of lasting 30 years. In a NZ context with lower expected bond returns, 3–4% is a more conservative benchmark.

Illustrative annual withdrawal amounts by starting balance:

Balance at 653% drawdown4% drawdown
$150,000$4,500/year$6,000/year
$250,000$7,500/year$10,000/year
$350,000$10,500/year$14,000/year
$500,000$15,000/year$20,000/year

These amounts supplement NZ Super (~$27,560/year single; ~$42,328/year couple in 2026).

Important: The 4% rule assumes the balance stays invested and continues generating returns. It doesn’t work if you withdraw everything into a low-interest savings account.


What Fund Should You Be In During Drawdown?

This depends on how long you expect to need the money and whether you have other income.

Conservative fund (mostly bonds/cash)

  • Lower returns (~3–4% p.a.)
  • Lower volatility — balance relatively stable
  • Suitable if: very cautious, drawing down quickly, no other investments, no capacity for any balance fall

Balanced fund (50/50 growth/income)

  • Moderate returns (~5–6% p.a.)
  • Some volatility but recovers reasonably
  • Suitable for: most retirees who plan to draw down over 15–20+ years

Growth fund (mostly shares)

  • Higher returns (~7–8% p.a.) but significant year-to-year swings
  • Suitable only if: you have other income to cover day-to-day expenses so you’re not forced to sell at a low point; you have a 20+ year horizon (e.g., retiring at 65 with good health)

A common split approach:

  • Keep 2–3 years of planned withdrawals in a conservative fund (safe, accessible)
  • Keep the remainder in a balanced or growth fund (continues growing)
  • Replenish the conservative portion from the growth portion when markets are up

Not all KiwiSaver providers support this split within one scheme — you may need to use two providers, or switch providers for the drawdown phase.


Sequence-of-Returns Risk

The most dangerous scenario for a KiwiSaver drawdown is a major market fall in the first 1–3 years of retirement, combined with regular withdrawals.

Example:

  • $300,000 balance at 65, in a growth fund
  • Market falls 25% in year 1 → balance drops to $225,000
  • You withdraw $15,000 (5%) for living expenses → balance $210,000
  • Market recovers 25% in year 2 → balance rises to $262,500
  • You’re still $37,500 behind where you started, despite the recovery

The combination of withdrawals + a bad start permanently depletes the base. This is why reducing risk in the 2–5 years before and just after retirement is important — not because you can’t tolerate volatility emotionally, but because the mathematics penalise early losses during drawdown.


Making KiwiSaver Last — Practical Steps

1. Don’t withdraw a fixed dollar amount — adjust for your balance If markets have fallen, consider withdrawing slightly less for a period. If markets are strong, you may be able to withdraw more.

2. Delay drawing down if you don’t need it If NZ Super covers your essential expenses in early retirement, leave KiwiSaver invested. Every year of additional growth compounds the balance for later.

3. Review annually Check your balance, your drawdown rate, and your fund type each year. If your balance is tracking well above your needs, you may be able to increase withdrawals or leave more to your estate. If it’s depleting faster than expected, reduce the rate or consider part-time work.

4. Factor in NZ Super NZ Super is approximately $530/week (single, living alone) or $407/week per person in a couple. This is your floor income — KiwiSaver fills the gap above NZ Super for your target lifestyle. See KiwiSaver and NZ Super for a full breakdown.

5. Don’t ignore estate planning Your KiwiSaver balance forms part of your estate. If you die before drawing it down fully, the remainder goes to your estate according to your will. Make sure your will is current.


Staying in KiwiSaver vs Moving to Another Structure

Some retirees consider withdrawing KiwiSaver in full and reinvesting in term deposits, managed funds outside KiwiSaver, or rental property. The trade-offs:

StructurePIE tax advantageSimplicityLiquidity
Stay in KiwiSaverYes (max 28% PIR)YesYes (withdrawals on request)
Term depositsNo (taxed at marginal rate)YesNo (locked term)
Non-KiwiSaver PIE fundsYesYesYes
NZX sharesPartial (no PIR; dividends at marginal rate)NoYes
Rental propertyNoNoNo

For most retirees, staying in KiwiSaver for at least part of the drawdown makes sense because of the PIE tax cap and simplicity.
