How We Compare KiwiSaver Providers

Our comparison weighs eight factors: fees (the only variable guaranteed to affect your return, regardless of market conditions), historical performance (5-year minimum, ideally 10-year, after-fee figures — 1-year numbers are close to meaningless for manager skill), investment options (number and range of funds), risk levels (FMA’s standard 1–7 risk indicator), customer service reputation, ethical/responsible investing credentials, digital experience, and overall value (performance relative to fee, not fee or performance in isolation).

Two methodology notes worth understanding before reading the reviews below:

• Always compare after fee returns, not headline gross returns. A fund earning 8.5% gross with 1.2% fees delivers 7.3% net, a fund earning 8.0% gross with 0.31% fees delivers 7.69% net — materially better despite the lower headline number.
• A single year of outperformance means almost nothing. A growth fund that ranks #1 in one year is statistically no more likely to rank #1 the next. The FMA’s annual KiwiSaver report and Sorted’s Smart Investor tool remain the most authoritative independent NZ sources for after-fee, risk-adjusted returns by provider.

Simplicity KiwiSaver Review

Our comparison rating: 4.5/5 — Best for: lowest overall fees

Simplicity is a not-for-profit KiwiSaver manager that has built its entire identity around minimising cost. Its fee structure is among the lowest in the country: 0.24%–0.31% p.a. management fee depending on fund (with a flat $30/year member fee), and no performance fee. It donates 15% of revenue to charity rather than paying shareholder dividends.

Investment strategy: A globally diversified, passive index approach across NZ and international shares, primarily through low-cost index vehicles, tracking benchmarks like the NZX 50 and MSCI World.

Advantages: Genuinely the cheapest credible full-service option; regulated by the FMA with member assets held by an independent supervisor (Public Trust); simple, transparent structure.

Disadvantages: Digital experience is functional but less polished than newer providers like Kernel; less rigorous ethical screening than a dedicated ethical provider like Pathfinder.

Who it’s best for: Cost-conscious members of any age who want a simple, low-fee, passively managed fund and don’t need extensive fund customisation options.

Kernel KiwiSaver Review

Our comparison rating: 4.5/5 — Best for: transparent index investing, strong recent performance

Kernel is a newer (founded 2019), independent, index-focused manager built around radical fee transparency. Fees sit at a flat 0.25% p.a. on its diversified funds (High Growth, Balanced, Cash Plus), with no member fee and no admin fee — at least 39% below the industry average per Kernel’s own Morningstar-sourced comparison.

Investment strategy: Pure passive/index investing with an unusually wide range of individual index fund options for members who want to build a custom allocation, not just pick one diversified fund.

Performance: Kernel’s High Growth, Balanced, and Cash Plus funds ranked #1 for 3-year returns in their categories in the Morningstar KiwiSaver Survey to 31 March 2026. The High Growth fund also ranked number 1 for 1-year returns in its category.

Advantages: Best-in-class fee transparency; strong recent relative performance; broad fund customisation for engaged investors.

Disadvantages: A newer scheme (since 2019) means limited 10-year track record; more fund options can mean more decisions for members who just want simplicity.

Who it’s best for: Financially engaged members who want low-cost index investing with more granular control than Simplicity offers.

Milford KiwiSaver Review

Our comparison rating: 4/5 — Best for: active management with a genuine long-run track record

Milford is New Zealand’s best-known active KiwiSaver manager, running over NZ$8.4 billion in its Active Growth Fund alone across more than 103,000 members. It charges a base fund fee of ~1.05% p.a., plus a performance fee (up to 15% of returns above benchmark, subject to a high-watermark), bringing total fees to roughly 1.25% p.a. in a typical year, plus a $36/year member fee.

Performance: Over the 5 years to 31 March 2026, Milford’s Active Growth Fund returned 6.82% p.a. after fees and tax (at 28% PIR) — a figure that leads most other major growth funds over the same window, ahead of typical bank fund returns of roughly 5–6.5%. Milford has won the INFINZ Diversified Growth Fund Manager of the Year award four times in the past five years.

Advantages: Genuine, sustained after-fee outperformance versus most active peers over 5+ years; strong, consistent award recognition; was selected as a government default provider in 2021.

Disadvantages: Meaningfully higher fees than passive alternatives — Milford needs to outperform a low-cost passive fund by roughly 0.7%+ per year, every year, just to justify the fee premium; outperformance in any active fund is never guaranteed to continue.

Who it’s best for: Members comfortable paying a premium for professional active management with a demonstrated (though not guaranteed-to-continue) long-run edge.

Generate KiwiSaver Review

Our comparison rating: 3.5/5 — Best for: NZ/Australia-focused active management

Generate is an Auckland-based active manager, established 2013, and was one of the original nine default providers appointed in 2021. Fees run around 1.09% p.a. for its Growth fund, with a roughly $36/year member fee. Its Focused Growth fund offers a more concentrated, higher-conviction portfolio than the standard Growth fund.

Performance: Generate’s Growth and Focused Growth funds have delivered solid absolute returns over 5–10 year periods, though — per independent reporting including a 20 April 2026 RNZ comparison — lower-fee passive managers (Simplicity, Kernel, SuperLife) have recently outpaced well-known active managers including Generate on both 1-year and 3-year numbers.

Advantages: Established track record since 2013; NZ/Australian equity-heavy exposure appeals to members wanting local-market weighting; default provider status is a quality signal.

Disadvantages: Fees sit above the growth-fund category average without a clearly sustained performance edge to match, based on recent independent comparisons.

Who it’s best for: Members who specifically want active management with meaningful NZ/Australian market exposure, rather than a globally-weighted passive fund.

Pathfinder KiwiSaver Review

Our comparison rating: 4/5 — Best for: ethical/responsible investing

Pathfinder (founded 2009, B Corp certified) is New Zealand’s most explicitly values-driven KiwiSaver provider, applying its ethical framework across every fund rather than offering one bolted-on “ethical option.” Fees range from 0.96%–1.28% p.a. depending on fund, plus a $27/year member fee (waived for balances under $1,000 or members under 18).

Ethical credentials: UN Principles of Responsible Investment (UNPRI) signatory with an A+ governance rating; Responsible Investment Association of Australasia (RIAA) certified; Mindful Money’s “Best Ethical KiwiSaver Provider” award winner multiple years running; donates 20% of management fees to member-chosen charities.

Advantages: Genuinely rigorous ethical screening — excludes companies on both regulatory and broader societal/environmental harm grounds, not just a minimal weapons/tobacco exclusion list; strong independent ethical certifications.

Disadvantages: Mid-range fees for an active manager; smaller funds-under-management than the major providers (not necessarily a quality issue, but means less operating scale).

Who it’s best for: Members for whom ethical alignment is a primary, non-negotiable criterion in choosing a provider.

ANZ KiwiSaver Review

Our comparison rating: 2.5/5 — Best for: existing ANZ banking customers wanting convenience

ANZ is New Zealand’s largest KiwiSaver provider by membership, though it lost default-provider status in the 2021 government review. Growth fund fees run 0.85%–1.06% p.a., with no flat member fee (a fee ANZ removed in September 2021).

Advantages: Convenience for existing ANZ banking customers, integrated app experience, broad fund range including the older OneAnswer scheme for specialist options (NZ shares, property, infrastructure).

Disadvantages: Among the higher fee levels in the market — roughly $4,600 more over 10 years on a $50,000 balance compared to a 0.31% passive fund, before compounding on those fee savings is even factored in; lost default status specifically because its fee levels and fund structure didn’t meet the 2021 quality criteria.

Who it’s best for: Members prioritising banking convenience above fee minimisation — though it’s worth a genuine comparison against lower-fee alternatives if you’ve simply never reviewed the account.

ASB KiwiSaver Review

Our comparison rating: 2.5/5 — Best for: ANZ alternative with a slightly lower fee

ASB, like ANZ, was not selected as a 2021 default provider. Growth fund fees run 0.75%–1.00% p.a., marginally cheaper than ANZ, with no flat member fee — a small advantage for lower balances.

Advantages: Slightly more competitive fees than ANZ within the bank-affiliated tier; no member fee benefits smaller balances specifically.

Disadvantages: Still significantly more expensive than passive providers — the gap between ASB’s ~0.75%–1.00% and a 0.31% passive fund is roughly $3,000 over 10 years on a $50,000 balance.

Who it’s best for: Existing ASB banking customers who want to stay within their bank ecosystem but are choosing between ASB and ANZ specifically.

BNZ KiwiSaver Review

Our comparison rating: 3.5/5 — Best bank-affiliated provider

BNZ is the standout among bank-affiliated providers, and the only major bank scheme to retain 2021 default provider status. Growth fund fees run 0.40%–0.55% p.a. — notably lower than ANZ (0.85%+) and ASB (0.75%+) — plus an $18/year member fee.

Why BNZ kept default status when ANZ and ASB didn’t: the 2021 review set minimum fee caps and required default funds to be growth-oriented rather than cash-based. BNZ restructured ahead of the review to meet the new criteria; ANZ, ASB, and Westpac did not.

Advantages: Clearly the most competitive bank-affiliated provider on fees; hybrid approach blending passive index exposure with active decisions; new members defaulted into BNZ land in a Balanced fund, a materially better starting point than the old cash-fund default system.

Disadvantages: Still a meaningful fee premium over dedicated passive providers like Simplicity or Kernel, even if it’s the cheapest bank option.

Who it’s best for: Members who want to stay with a major bank provider but care enough about fees to specifically choose the best-value bank option rather than defaulting to their existing bank.

KiwiSaver Fees Explained

Management fees are charged as a percentage of your balance annually — the single biggest cost lever, since it compounds against you every year regardless of returns.

Fund charges can include underlying fund costs (for funds that invest in other funds) and, for active managers like Milford, a performance fee layered on top of the base management fee.

Contribution costs — most NZ KiwiSaver providers charge no fee to contribute or switch funds/providers; switching is free by law, with no exit penalties permitted.

Why a small fee difference matters over decades: per Sorted’s industry benchmarks, 2026 average fees run roughly 0.90% for conservative funds, 1.01% for balanced, and 1.23% for growth. The difference between a 0.25% fund and a 1.25% fund can cost a typical member tens of thousands of dollars over a 30-year working life, purely from compounding fee drag — entirely separate from any difference in fund performance.

KiwiSaver Risk Profiles Explained

Risk profile	Typical growth-asset allocation	Suited for
Conservative	~20–30% growth assets	Short time horizon (under 3–4 years), or risk-averse investors near a withdrawal
Moderate	~35–45% growth assets	Medium-short time horizon, wanting some growth with reduced volatility
Balanced	~50–65% growth assets	Medium time horizon (5–10 years), moderate risk tolerance
Growth	~70–90% growth assets	Long time horizon (10+ years), comfortable with market volatility
Aggressive/High Growth	~95–100% growth assets	Very long time horizon (15+ years), high risk tolerance, typically younger members

General principle: the longer your time horizon before you’ll withdraw (first home, or age 65), the more growth-asset exposure you can typically tolerate, since you have more time to ride out short-term volatility.

How to Choose the Best KiwiSaver Provider

• Determine your risk profile based on your time horizon (see table above) — this matters more than provider choice itself.
• Filter providers by fund availability at your risk level — not every provider offers every risk tier.
• Compare after-fee costs on your actual balance using Sorted’s Smart Investor tool, not just headline percentages.
• Check 5–10 year after-fee performance, not 1-year numbers, for any active fund you’re considering.
• Decide if ethical screening matters to you — if it does, weight this heavily, since it’s a values decision, not just a financial one.
• Review digital experience and customer service if you’ll want to self-manage your account regularly.
• Confirm current details directly on the provider’s Product Disclosure Statement (PDS) before switching or joining.

Should You Switch KiwiSaver Providers?

When switching may make sense: you’re paying meaningfully above-market fees without a demonstrated performance edge to justify it; your risk profile has changed (e.g., approaching a withdrawal); you were placed in a default provider/fund and never actively chose it; your values around ethical investing have shifted.

What to check before switching:

• Switching is free by law — no exit fees or break penalties are permitted for KiwiSaver transfers
• Your 3-year first home withdrawal eligibility clock is based on total KiwiSaver membership, not membership with any single provider — switching does not reset it
• You can only hold one active KiwiSaver account at a time
• Confirm the new provider’s fund actually matches your intended risk profile before transferring, rather than switching on fees alone

KiwiSaver and Take-Home Pay

Your KiwiSaver contribution rate — 3.5% (default from 1 April 2026), or optionally 4%, 6%, 8%, or 10% — is deducted directly from your gross pay through PAYE, alongside income tax, the ACC earner’s levy, and any student loan repayment. Choosing a higher contribution rate genuinely reduces your take-home pay today in exchange for a larger retirement balance — a trade-off worth seeing in real numbers rather than estimating by feel.
