What Actually Happens to Your KiwiSaver on Your 65th Birthday

If you are approaching 65 and have been quietly contributing to KiwiSaver for years, the rules around your account are about to change. Most providers do not proactively explain what changes. You usually get a letter summarising your options, and then everything stops being automatic. This is the most consequential transition point in your KiwiSaver life.

Three Things That Change Immediately

You can withdraw the balance. Once you qualify for NZ Superannuation (currently age 65) and have been a KiwiSaver member for at least five years, the scheme is no longer locked.^[1] You can take it all, leave it all, or draw from it on any pattern you want.

Your employer's contributions become optional. Employers are not required to contribute to your KiwiSaver once you turn 65.^[2] Some continue voluntarily. Many do not. You have to ask.

The government contribution stops. Following Budget 2025 changes effective 1 July 2025, the annual government contribution is up to $260.72, paid at 25 cents for every $1 you contribute and capped once you reach $1,042.86 of personal contributions in a year. It is available to members aged 16 to 65 with income below $180,000.^[3] At 65, eligibility ends entirely, even if you keep contributing.

What Does Not Change

Your investment continues earning returns and paying PIE tax. Your fund choice does not reset. Your contributions, if you are still working, continue at your nominated rate unless you elect to opt out, which you can now do.

Note that the default KiwiSaver contribution rate for both employees and employers rises from 3% to 3.5% from 1 April 2026.^[4] For most workers this is automatic. Past 65, neither half applies to you by default. It is payable only if you and your employer both opt in.

The day you turn 65, your KiwiSaver shifts from a long-horizon accumulation account to a short-horizon drawdown account. Those are not the same kind of investment problem.

The Decumulation Transition No-one Walks You Through

This is the part most providers do not explain. An aggressive or growth-oriented fund still has a place for someone with a 25 to 30 year retirement horizon, which most 65-year-old Kiwis have.^[5] But the volatility tolerance of a 65-year-old drawing income from a fund is materially different from that of a 35-year-old contributing into one. Sequence-of-returns risk becomes the dominant concern.

Some providers move members to a post-retirement conservative fund automatically. That may or may not be right. We see many 65-year-olds left in funds that do not match their actual drawdown plan, because the provider's default was applied without anyone asking what the plan was.

The 90-Day Decision Window

In the first 90 days after your 65th birthday, the practical questions worth answering are:

1. Do you still want to be contributing, given there is no employer match and no government contribution to chase?
2. Should you change funds, now that your horizon has shifted from “until retirement” to “throughout retirement”?
3. How much do you actually need to withdraw, if any, in the next year?
4. Is the KiwiSaver wrapper still the best place for these funds, or are there structural reasons (estate planning, drawdown flexibility, fee structures) to move some or all of it elsewhere?

What Good Advice Looks Like

The NZ Society of Actuaries' Retirement Income Interest Group has published rules of thumb to help structure drawdown, but these are starting points, not final answers.^[5] The right drawdown plan depends on your other income, and NZ Super remains the largest single retirement income source for most Kiwis.^[6] It also depends on your housing equity, your health, and your bequest intentions.

If you are within two years of 65 and have not had this conversation yet, it is genuinely worth having. The decisions made in the first 90 days set the trajectory for the next 25 years.
