Best Investment Managers in New Zealand — 2026 Comparison

Your KiwiSaver account is likely to be the single biggest investment you ever make. By the time you reach 65, those regular contributions — yours, your employer's, and the government's — can compound into a sum that defines whether you retire comfortably, travel, help your kids, or just make ends meet. Choosing who manages it is one of the most important financial decisions you will make, and it is one that most New Zealanders spend less time on than picking a new phone plan.

We wanted to fix that. So we did the work for you.

How We Evaluated Every Major KiwiSaver Provider

We went through every quarterly fund update on the FMA Disclose Register for all 31 licensed KiwiSaver providers. These are the legally required reports every fund manager must publish — returns, fees, asset mix, the people running the money. We looked at five-year and ten-year performance, what they charge, who owns them, how long they have been doing it, and whether the people managing your retirement savings have enough experience to justify the fee.

What emerged is a market that splits into three distinct tiers: a handful of providers that genuinely earn their fees, a large middle that charges active prices for average results, and a small group of ultra-low-cost passive funds that have quietly outperformed most of them.

This guide is not here to pick a single provider and tell you to switch today. The right manager depends on what matters most to you — keeping costs as low as possible, backing a long track record of active outperformance, or trusting an ownership structure you believe in. What it does do is put all the numbers in one place, properly sourced, so you can make that call for yourself.

Our Top Three Picks for Most New Zealanders

If you want to skip the detail and just know where to start, here are our recommendations. We picked these after comparing returns, fees, ownership, management longevity, and investment philosophy across every licensed KiwiSaver provider.

Simplicity

★ 4.9 ★★★★★ (592 Reviews)

Simplicity is a nonprofit KiwiSaver and investment fund manager charging 0.25% p.a. across all six KiwiSaver funds. 100% owned by the Simplicity Foundation, a registered charity. Over 190,000 members. Seven rounds of fee cuts since launch in 2016. Fifteen percent of management fees donated to NZ charities. Founded by Sam Stubbs (ex-Tower Investments CEO, Goldman Sachs).

1 Simplicity — Best All-Round Value

Simplicity charges 0.25% across all six KiwiSaver funds — the joint-lowest fee in the market — and delivered 6.01% per year after tax over five years. That combination of lowest cost and above-median returns is difficult to argue with, especially when you consider who is behind it.

Why we picked it: Simplicity is a nonprofit. It is 100% owned by the Simplicity Foundation, a registered charity. There are no shareholders expecting dividends. As the scheme has grown past 190,000 members, Simplicity has passed the benefits of scale back through seven rounds of fee cuts — a pattern no other provider in New Zealand has matched. Fifteen percent of all management fees go to the Foundation, which has distributed over $13 million to New Zealand charities since inception.

Simplicity was founded in 2016 by Sam Stubbs (ex-Tower Investments CEO, Goldman Sachs, Fay Richwhite). It launched with $1 million of Stubbs' own money and started with six staff taking no salary. The management team comes from deep institutional backgrounds — not tech founders trying their hand at finance.

Simplicity invests passively — it tracks market indices rather than trying to pick winning stocks. Decades of global research show that most active managers fail to beat their benchmark after fees over long periods. Simplicity removes that risk entirely.

The catch: Simplicity launched in 2016, so it has ten years of history rather than the 20 or 30 of an NZ Funds or Fisher Funds. Its non-KiwiSaver managed fund range is more limited than a dedicated platform like Kernel. You will never beat the market by a wide margin with Simplicity. You will also never underperform it by a wide margin. For most people saving for retirement, that is exactly the right trade-off.

2 Milford — Best for Long-Term Active Growth

Milford's Active Growth Fund launched in October 2007 — nearly 19 years ago. It has returned 6.82% per year after tax over the past five years on a 1.05% base fee. With $8.4 billion in the Growth Fund alone and roughly $32 billion across all funds, Milford is the largest independent fund manager in New Zealand by a margin.

Why we picked it: Nobody else in the independent space has Milford's depth of resource. The firm was founded in 2003 by Brian Gaynor, one of the most respected investment minds in New Zealand history. The investment team has meaningful personal wealth in the same funds they manage. The performance fee structure — 15% of returns above a 10% hurdle rate, capped, with a high-water mark — is rare in its honesty: Milford only collects extra when they genuinely outperform. In the year to March 2026, performance fees charged were 0.00% because the fund did not beat its hurdle. That is exactly how the structure should work.

The catch: Active management means active risk. Milford's Growth Fund dropped over 16% in 2022. If you panic-sell during a drawdown, you lock in losses that would have recovered. And at 1.05%, you are paying roughly four times what Simplicity charges. That premium only makes sense if you stay invested through the bad years and give the strategy enough time — seven to ten years at minimum — to work.

3 Generate — Strongest Returns Open to All

Generate's Growth Fund returned 8.36% per year after tax over five years — the highest of any general-public KiwiSaver provider with substantial assets. Over ten years it has returned approximately 10.5% before tax. Among the major managers that any New Zealander can join, no one has posted better numbers over the period most investors care about.

Why we picked it: Generate is founder-led by Henry Tongue (CEO) and Sam Goldwater (CIO) — both with over 20 years of financial markets experience. It has built its reputation primarily on investment performance rather than marketing. The Growth Fund leans harder into equities than most peers — which explains some of the outperformance, and some of the risk. The firm manages roughly $2.05 billion for about 52,000 members and has grown rapidly through results rather than advertising. The investment team has been in place for most of Generate's 14-year history — relatively stable leadership for a private manager.

The catch: Generate charges 1.37% — one of the higher fees in the market. Higher risk plus higher fees means you are paying a significant premium for that outperformance. If Generate's returns revert toward the category average — as most active managers' eventually do — you will be left paying 1.37% for results that no longer stand out. Generate suits investors who believe its investment team can continue to deliver, understand that the past five years outperformance is a reason to pay attention rather than a reason to be complacent, and accept the higher equity weighting that drives both the returns and the volatility.

What You Actually Pay — And What It Costs You

Fees are the only part of investing you can control. Here is what each percentage point costs on a $100,000 portfolio earning 6% before fees over 30 years.

The gap between Simplicity at 0.25% and NZ Funds at 2.01% is about $195,000 on a $100,000 starting balance over 30 years. That money is yours — or it is your fund manager's. Fees compound in their favour, not yours.

This is not an argument that low fees always win. NZ Funds returned 7.81% after tax at 2.01% — giving investors more wealth than they would have had in Mercer at 0.88% with 5.07%. The fee is guaranteed. The outperformance is not. You need to decide whether you believe your manager can maintain their edge, and for how long.

Who Owns Your Manager — And Why It Matters

Your KiwiSaver provider is a business. Who ultimately profits from the fees you pay is one of the most important and least discussed aspects of choosing a scheme.

Complete KiwiSaver Provider Directory — All 31 Licensed Schemes

Every FMA-licensed KiwiSaver provider is listed below. Use this as a reference when comparing options — particularly the founding year and what distinguishes each provider from the rest.

How to Verify Any Provider Yourself

Every scheme listed above is licensed by the Financial Markets Authority. You can independently verify any of this data in two minutes:

1. Go to the FMA Disclose Register at disclose-register.companiesoffice.govt.nz
2. Search for the provider or fund name
3. Open the most recent Quarterly Fund Update — this is the legally required document showing actual returns and fees charged
4. Open the Product Disclosure Statement — this shows the current fee structure and investment approach
5. Check the provider appears on the Financial Service Providers Register at fsp-register.companiesoffice.govt.nz with a Managed Investment Scheme licence

How to Actually Choose

1. Find your current provider on our KiwiSaver Fund Comparison tool. Look at their return, their fee, and how long they have been managing money. If you are paying 1.13% for Fisher Funds' 5.0% after tax while Simplicity charges 0.25% and returns 6.01%, or AMP at 0.85% returns 7.39%, ask yourself what the extra fee is buying.
2. Decide passive or active. Passive (Simplicity, Kernel, Foundation Series, AMP) means you accept market returns and pay almost nothing. Active (Milford, Generate, NZ Funds, SBS) means you are betting the manager can continue to outperform. If you are not sure, passive is the safer default — decades of global data support it.
3. Look at the numbers together. Five-year return minus fee. Not one or the other — both. A 10.32% return at 1.17% might beat a 6.01% return at 0.25% — but both need to earn their place. Check how long the manager has been doing this. A 13-year track record (Generate) is not the same as a 38-year one (NZ Funds) or a 172-year one (AMP).
4. Check who profits from your fees. A nonprofit (Simplicity), a mutual (MAS, SBS), a majority trustee-owned firm (Fisher Funds, 51% TSB Community Trust), an employee-owned firm (Pie Funds, where $100M+ of staff money is co-invested), and an ASX-listed bank (ANZ, Westpac) are four very different structures. Know which one holds your retirement savings and why.
5. Read the actual PDS. Not the marketing website. The Product Disclosure Statement on the Disclose Register. Look at the fee table and the "other charges" section. Some funds charge $30 to $36 membership fees on top of the percentage.
6. Review every two to three years. Fees change. Managers change. Performance changes. Switching KiwiSaver providers is free, takes about ten minutes online, and does not affect your balance. Your current provider will not remind you of this.

If You Remember Nothing Else

About $136 billion sits in New Zealand KiwiSaver accounts. Every percentage point of fees is real money — your money — that compounds in favour of whoever charges it.

Over the past five years, the after-tax spread between the top growth fund (8.78%) and the bottom established provider (4.51%) is over four percentage points per year. That is not small. On a $100,000 balance over 20 years, that difference is hundreds of thousands of dollars.

The provider with the strongest returns (Generate, 8.36% for the general public) charges five times what the cheapest provider charges (Simplicity, 0.25%). Both are legitimate choices. The difference in outcome depends on whether you believe the outperformance will continue.

If you remember nothing else from this guide, do these three things:

1. Find your provider on our KiwiSaver Fund Comparison tool. Look at their five-year return and fee. Compare them to the providers ranked above and below. Is your manager earning their fee?
2. Know who profits from your money. A registered charity, a member-owned mutual, an employee-owned partnership, and an ASX-listed bank are four very different organisations. Know which one manages your retirement savings and whether their incentives align with yours.
3. Switch if the numbers do not stack up. Switching KiwiSaver providers is free. The new provider handles the paperwork. Your balance transfers intact. Ten minutes online could save you tens of thousands of dollars over your working life. The provider you are leaving will never tell you this.

Every return figure and fee in this guide is sourced from each manager's own published Quarterly Fund Updates and Product Disclosure Statements on the FMA Disclose Register, the Sorted Smart Investor tool supported by Te Ara Ahunga Ora Retirement Commission, and provider websites — all publicly available as at July 2026. Returns are after fees and after tax at the highest PIR of 28% unless stated otherwise. Before-tax returns are shown where the provider publishes both figures. Founding years are from provider websites, the NZ Companies Office, and public records — approximate dates are marked. Past performance does not guarantee future returns. Fees and ownership structures can change. Always check the current PDS before making a decision.
