Koura KiwiSaver in NZ (2026): Is the Self-Build, Bitcoin-Option Scheme Right for You?

Koura's robo-advice model lets you build your own KiwiSaver from index funds and add a small Bitcoin allocation. How it works, the fees, the crypto risk, and who it suits.

TL;DR: Koura is a robo-advice KiwiSaver scheme where you build a portfolio from individual index funds and can add a small Bitcoin allocation — capped at 10% of your balance as at 17 November 2025 ¹. The Bitcoin Fund charges 1.1% a year ³. Crypto is high-volatility and unproven over a working life, so for most people it's a small "satellite" at most, not the core.

Koura Wealth is one of New Zealand's smaller, newer KiwiSaver providers, and it does two things that set it apart from the big bank and index schemes. It uses robo-advice (a digital tool) to recommend a portfolio rather than a human adviser, and it offers a dedicated Bitcoin Fund you can blend into your KiwiSaver — something almost no other scheme does.

This review covers how the model works, how the Bitcoin option actually functions, what it costs, and — most importantly — who it suits and who should steer clear. The figures are correct as at 17 November 2025; crypto rules and caps change, so check the current Product Disclosure Statement before acting.

What is Koura KiwiSaver and how does its robo model work?

Koura is a robo-advice (digital advice) KiwiSaver scheme. Instead of meeting an adviser, you answer questions in Koura's guided online tool, and it recommends a portfolio built from its individual index and sector funds ⁴.

That's the first thing that makes Koura different. Most KiwiSaver schemes put you in a single diversified fund — Conservative, Balanced, Growth and so on. Koura instead lets you assemble a portfolio from building blocks, either by accepting the tool's recommendation or by manually building a custom mix across its funds ⁴.

There are guardrails on how much you can hold in each block:

• Core funds (the broad equity and fixed-interest building blocks): up to 100%
• Emerging Markets: up to 50%
• Specialty funds, including the Bitcoin Fund: up to 10% ⁴

The robo model has genuine appeal. It's cheap to run, it nudges you toward a diversified mix rather than a single off-the-shelf fund, and it gives engaged members more control. The trade-off is that a digital tool can't know your full picture the way a person can — your other investments, your mortgage, your insurance, your job security, or how you'd actually behave in a crash. It answers the questions you're asked; it can't ask the ones you didn't think of.

How does Koura's small Bitcoin allocation actually function?

The headline feature is the Bitcoin Fund. Koura lets you add a slice of Bitcoin exposure to an otherwise conventional index portfolio, rather than going all-in on crypto.

A few mechanics matter here. As at 17 November 2025:

• Your Bitcoin allocation was capped at a maximum of 10% of your total KiwiSaver balance ¹.
• Koura automatically rebalanced your Bitcoin holding back to its target once it exceeded 15% of your total balance, or at least every six months ².

The rebalancing rule is more important than it looks. Bitcoin is volatile, so a 10% allocation can quickly drift higher after a strong run. By trimming it back when it grows past 15%, Koura stops a small "satellite" turning into a dominant chunk of your retirement savings without you deciding to. It's a sensible piece of design — though it cuts both ways, because it can mean selling after a rise and buying back after a fall.

The Bitcoin Fund launched on 23 May 2022 and invests via a fund managed by Fidelity Digital Assets ³. So you're not holding coins in a personal wallet — you're holding units in a regulated KiwiSaver fund that gets Bitcoin exposure through an institutional manager.

Note: these caps changed after this review's date. On 21 May 2026 Koura raised the Bitcoin allocation cap to 20% and the rebalancing threshold to 30% ¹². Always check Koura's current Cryptocurrency page and PDS for the live figures.

What are the risks of crypto inside KiwiSaver?

This is the part that decides whether the Bitcoin option is for you. KiwiSaver is, for most people, a multi-decade retirement product, and Bitcoin sits at the far high-volatility end of the spectrum.

The honest points to weigh:

• Extreme volatility. Bitcoin can rise or fall by large amounts over short periods — far more than shares. A 10% allocation can swing the value of your whole balance noticeably.
• No income, no underlying earnings. Unlike shares (company profits) or bonds (interest), Bitcoin produces no cash flow. Its price rests entirely on what the next buyer will pay.
• Short, unproven history. Bitcoin has existed since 2009 and Koura's fund only since 2022 ³. That's a fraction of a working life, with no track record across a full range of market conditions.
• Concentration in a single asset. Crypto isn't a diversified basket; it's one asset class with its own boom-and-bust cycle.

None of this makes a small allocation automatically wrong. But it does mean Bitcoin belongs, if at all, in the "money I can leave alone for a very long time and could afford to see fall hard" category — not the core of a retirement plan. KiwiSaver and managed funds are investments whose value can fall; they are not savings accounts, and nothing about a crypto allocation is guaranteed.

What are Koura's fees compared with index schemes?

Fees compound hard over a working life, so they're worth getting right. Koura's Bitcoin Fund charges a total annual fund fee of 1.1% — made up of a 0.85% manager's basic fee plus 0.25% other management and administration charges, with no performance fee ³.

That 1.1% is well above what a plain-vanilla index fund costs. For context, low-cost index KiwiSaver growth funds in New Zealand typically charge in the region of 0.25% to 0.60% a year — you can see the cheaper end in our low-fee KiwiSaver providers guide. The higher Bitcoin fee partly reflects the cost of crypto custody and the institutional fund structure behind it.

Source: Provider PDS and fund documents; Sorted Smart Investor for standardised comparison. Koura's non-Bitcoin index funds carry their own (lower) fees — check the current PDS. Figures current as at 17 November 2025; past performance is not a reliable indicator of future performance.

The takeaway isn't "Koura is expensive" full stop — its broader index funds are cheaper than the Bitcoin Fund. It's that the crypto exposure specifically carries a meaningfully higher fee, so the case for it has to rest on more than cost.

How are Koura's underlying funds built?

Underneath the robo tool, Koura's portfolios are assembled from individual index and sector funds rather than one all-in-one diversified fund ⁴.

In practice that means your "growth" allocation might combine a broad global equity block, a New Zealand and Australian block, an Emerging Markets block (capped at 50%), and a fixed-interest block, with the option to add a specialty fund such as Bitcoin (capped at 10%) on top ⁴. The robo tool stitches these together based on your answers, or you set the weights yourself.

This building-block approach is closer to how an adviser or a sophisticated DIY investor would structure a portfolio than the single-fund model most schemes use. It offers more control and transparency. The flip side is that more control means more decisions, and more scope to build something poorly diversified or too concentrated if you're not careful — which is exactly where the caps, and a second opinion, earn their keep.

Like every KiwiSaver fund, Koura's funds must publish a standardised risk indicator on a 1-to-7 scale and disclose fees and returns on the same basis in their quarterly fund updates and on Sorted's Smart Investor tool ⁸. That lets you compare Koura against the index schemes directly — a useful exercise covered in how to choose a KiwiSaver fund.

Who is Koura suited to, and who should steer clear?

Koura tends to fit a fairly specific type of member.

It may suit you if you:

• Are comfortable with a digital, self-directed approach and don't want a single off-the-shelf fund.
• Want the building-block control to construct your own mix from index funds.
• Specifically want a small, regulated way to get Bitcoin exposure inside KiwiSaver, and understand the risk.
• Have a long time horizon and a genuine tolerance for volatility — the same test that applies to any aggressive KiwiSaver fund.

It's probably not the right fit if you:

• Want the lowest possible fee — the Bitcoin Fund's 1.1% is well above index-fund levels ³.
• Are close to retirement, buying a first home soon, or otherwise need the money inside five years.
• Would lose sleep over a sharp fall, or would be tempted to switch funds at the bottom.
• Prefer a human adviser who can see your whole financial picture rather than a digital questionnaire.

There's no single "best" provider here — Koura is one of many, and it's worth seeing the full field in our KiwiSaver providers list. The robo-and-Bitcoin combination is a genuine point of difference, but a point of difference only matters if it fits your situation.

How does the Bitcoin option fit the FMA's risk framework?

KiwiSaver is regulated, and that regulation gives you tools to assess Koura on a level playing field.

The Financial Markets Authority (FMA) regulates all KiwiSaver schemes and requires standardised disclosure — including the risk indicator and quarterly fund updates — under the Financial Markets Conduct framework ⁹. Every fund, Koura's included, must publish a risk indicator on the same 1-to-7 scale, where 1 is lowest risk and 7 is highest ⁸.

Higher-volatility assets such as Bitcoin sit at the high end of that scale ⁸. The FMA has also noted growing interest in crypto-asset exposure within regulated investment products, alongside the elevated volatility risk these carry ⁹. So the regulator isn't banning crypto in KiwiSaver, but the framework is built to make sure the risk is disclosed plainly rather than buried.

The practical upshot: before you decide, pull up Koura's Bitcoin Fund on Sorted's Smart Investor and read its risk indicator and fees against the index funds you'd otherwise hold. If the number sits at the top of the scale, that's the framework telling you what you're taking on.

What should you weigh before adding crypto to retirement savings?

A short, practical checklist before committing any of your KiwiSaver to Bitcoin:

Two of those deserve a flag. First, the government contribution is now smaller: from 1 July 2025 the maximum was halved to $260.72 a year (25c per $1, down from $521.43), and you need to contribute at least $1,042.86 of your own money in the 1 July to 30 June year to get the full amount ⁵. Members earning over $180,000 are no longer eligible ⁶. Second, default minimum contributions are rising — 3% now, 3.5% from 1 April 2026, and 4% from 1 April 2028, with a temporary option to drop back to 3% for up to 12 months ⁷.

Those settings affect every dollar you put in, whatever fund or provider you choose, and they're an easy place to leave money on the table.

Frequently asked questions

Is Koura KiwiSaver a good provider? It depends on what you want. Koura offers something most schemes don't — a robo-advice tool, building-block index funds, and a regulated Bitcoin option. That suits engaged, self-directed members who specifically want crypto exposure or more control. People focused purely on the lowest fee, or who want a human adviser, may prefer other providers. Compare it on Sorted's Smart Investor before deciding ⁸.

How much of my KiwiSaver can I put in Bitcoin with Koura? As at 17 November 2025, Koura capped a member's Bitcoin allocation at a maximum of 10% of their KiwiSaver balance, and automatically rebalanced it back to target once it exceeded 15% ¹². Those limits were later raised (to a 20% cap and 30% rebalancing threshold on 21 May 2026), so check Koura's current Cryptocurrency page and PDS for the live figures ¹².

What does Koura's Bitcoin Fund cost? The Bitcoin Fund charges a total annual fund fee of 1.1% — a 0.85% manager's basic fee plus 0.25% other management and administration charges, with no performance fee ³. That's well above a typical low-fee index growth fund (roughly 0.25-0.60%). The fund launched on 23 May 2022 and invests via a fund managed by Fidelity Digital Assets ³.

Is having Bitcoin in my KiwiSaver risky? Bitcoin is high-volatility and produces no income, and Koura's fund has a short history (since 2022) ³. Its value can fall sharply, and returns are not guaranteed. KiwiSaver and managed funds are investments whose value can go down as well as up — they are not savings accounts. For most people a crypto allocation, if any, is a small satellite they can afford to leave alone for a very long time, not the core of a retirement plan.

How does Koura compare with low-fee index schemes? Koura's distinguishing features are robo-advice, self-built portfolios and the Bitcoin option — none of which most index schemes offer ⁴. The cost is higher on the Bitcoin Fund (1.1%) than on a plain index fund ³. Because every scheme publishes a standardised 1-7 risk indicator and fees on the same basis ⁸, you can compare them directly on Sorted's Smart Investor. See our low-fee KiwiSaver providers guide for the cheaper end of the market.

Should I switch to Koura for the Bitcoin option? That's a personal decision that depends on your timeframe, risk tolerance, fees and what else you hold — not something to do on the strength of a strong crypto run. Switching to chase a hot asset is a common way to buy high. If you're tempted, it's worth getting an independent view first.
