Pathfinder vs Booster Ethical KiwiSaver in NZ (2026): Two Responsible Funds Compared

Pathfinder and Booster both run ethical KiwiSaver options, but they screen, engage and price very differently. Exclusions, impact, fees, returns and certification compared for values-driven savers.

TL;DR: Pathfinder is an ethics-first manager that screens hard and pursues measurable impact; Booster runs a Socially Responsible Investment (SRI) range within a broader, mostly mainstream business. Demand is real — FMA research found 68% of New Zealand investors prefer their money invested responsibly. ² The honest answer is that "ethical" is a spectrum, not a label, so the right fit depends on how deep-green you actually want to go.

Pathfinder vs Booster KiwiSaver is a comparison many values-driven savers reach once they have decided they want their retirement money to do no harm — and, ideally, some good. Both providers offer a responsible option, but they sit at different points on the spectrum. New Zealand now holds about NZ$183.4 billion in responsible-investment assets, a segment that has grown quickly as a share of the market, so this is no longer a fringe choice. ³

This guide compares the two on exclusions, impact approach, fees, returns and certification, and helps you work out which suits a deep-green saver versus a more moderate one. Figures are point-in-time and dated where they matter.

What makes Pathfinder and Booster "ethical" KiwiSaver providers?

The word "ethical" carries no fixed legal meaning, so it is worth being precise about what each provider actually does.

Pathfinder is an ethics-first specialist. Responsible investing is the whole proposition rather than one product line: it builds funds around published exclusions, active engagement and measurable impact, and its KiwiSaver funds are independently certified by the Responsible Investment Association of Australasia (RIAA). That certification matters because it means an external assessor has checked the fund is "true-to-label" — its holdings match its marketing — rather than you taking the manager's word for it.

Booster is a broad, New Zealand-owned independent manager that offers a dedicated Socially Responsible Investment (SRI) range alongside its mainstream funds. The SRI funds apply ethical screens and avoid a defined list of harmful sectors, but they sit within a much larger business whose core funds are conventional. For many people that is a perfectly good fit; the point is simply that Booster offers an ethical option, whereas Pathfinder is built around one.

Neither approach is "more correct". One is a specialist; the other is a generalist with a strong responsible range. The demand underneath both is the same: the FMA's investor research found 68% of New Zealand investors would prefer their money invested ethically or responsibly. ²

How do their exclusion lists and screening differ?

Most responsible funds start with negative screening — a list of sectors they will not invest in. The common floor across genuine ethical funds includes fossil fuel production, controversial weapons, tobacco and gambling. Where providers differ is how far past that floor they go, and how strictly they apply it.

As a rule of thumb, an ethics-first manager like Pathfinder tends to exclude more sectors and apply tighter thresholds (for example, screening companies with even small revenue exposure to an excluded activity), while a broad manager's SRI range typically screens the headline "sin" sectors and applies materiality thresholds. Both are legitimate; they simply land in different places.

The practical lesson is not to trust the label. Two funds can use near-identical language and hold very different things. The exclusion list published in each fund's Statement of Investment Policy and Objectives (SIPO) and product disclosure statement (PDS) is what actually binds the manager — read that, not the brochure.

Does Pathfinder's impact approach differ from Booster's responsible funds?

Yes, and this is the clearest dividing line between them.

Negative screening only tells you what a fund avoids. Impact and engagement are about what it actively tries to achieve. Pathfinder leans into both: it tilts towards companies it judges to be doing measurable good, and it uses its shareholder position to engage with companies and vote on issues. Booster's SRI range is primarily screening-led — it removes harmful holdings — with engagement applied across the wider firm rather than as the headline feature of the range.

If you care mostly about not funding harm, a well-screened fund from either provider can do that. If you also want your money working towards positive outcomes — and want a manager whose entire identity is built around proving it — that pushes towards the ethics-first end of the spectrum. Be realistic about the trade-offs, though: a tighter, more concentrated ethical portfolio can behave differently from the broad market in any given year, sometimes better and sometimes worse.

What are Pathfinder vs Booster fees in 2026?

Fees are the one variable you control with certainty, and over a working lifetime they compound. Ethical funds have historically sat at the higher-fee, more-active end of the market, so it is fair to check what you are paying.

The Pathfinder KiwiSaver Growth fund carries a total annual fund charge of roughly 1.28%–1.37% of your balance, plus an annual member fee of about $27. ⁴ That is an actively managed, ethics-first price — well above a low-cost index fund and broadly in the range you would expect for a screened, impact-tilted growth portfolio. Booster's SRI range is also actively managed and screened, so it sits in a similar active band; you should confirm the exact total annual fund charge for the specific Booster SRI fund you are considering on its current fund update, because Booster runs several funds at different price points.

A few honest points on fees:

• Compare like with like. Put a Growth fund against a Growth fund, on a total-annual-fund-charge basis, including any fixed member fee.
• A higher fee is not automatically bad. Active screening and engagement cost more to run than passive index tracking. The question is whether the after-fee, after-tax return justifies it.
• Small percentages move large dollars. A one-percentage-point fee difference compounds heavily over 30 years, so it deserves a deliberate decision, not a guess.

How have their ethical funds performed against mainstream funds?

The old assumption was that "going ethical" meant accepting lower returns. The evidence over recent years has been more nuanced than that, and a single period — good or bad — proves very little.

A few principles to keep you honest when comparing:

• Match the risk category. A growth fund will out-return a balanced fund in most years simply because it holds more shares, not because it is "ethical" or "better managed". Compare Growth with Growth.
• Use after-fee, after-tax returns. That is what actually lands in your account. Headline gross numbers flatter higher-fee funds.
• Five years is the minimum useful window. KiwiSaver is a 30-to-40-year product; one strong year tells you almost nothing.

Returns are not guaranteed. The value of investments can go down as well as up and you may get back less than you invested. Past performance is not a reliable indicator of future performance. The cleanest way to see live, like-for-like figures is each fund's official page on Sorted's Smart Investor and its latest quarterly fund update — compare the same risk category, over the same period, on an after-fee, after-tax basis, before drawing any conclusion.

Does going ethical actually cost you returns?

This is the question most values-driven savers really want answered, and the honest version is: not necessarily, but it depends.

Excluding whole sectors changes a portfolio's makeup. In a year when, say, energy stocks soar, a fossil-fuel-free fund may lag the broad market; in a year they slump, it may do better. Over the long run, a well-run screened fund can perform competitively with a mainstream fund of the same risk level — but there is no guarantee either way, and concentration can add short-term volatility. Anyone who tells you ethical investing always costs returns, or always beats the market, is overstating the case in both directions.

What you can control is the cost side. If two ethical Growth funds offer broadly similar screening, the one with the lower total annual fund charge starts each year slightly ahead. That is why fees, certification and after-fee returns are worth looking at together rather than in isolation. Our Booster vs Simplicity comparison shows how much a fee gap alone can move a balance over decades.

It is also worth remembering the structural tailwinds that apply whatever fund you choose. If you qualify, the Government adds 50c per $1 you contribute, up to a maximum of $521.43 a year — meaning you need to contribute at least $1,042.86 in the KiwiSaver year to receive the full amount. ⁵ Most employees also contribute at the 3% minimum, matched by a 3% minimum employer contribution. ⁶ These figures are set by the Government and change — both the contribution rate and the government contribution were due to change from 2025–2026, so check current figures at ird.govt.nz before relying on them.

Which suits a deep-green saver vs a moderate one?

This is where the comparison resolves into a practical choice.

A deep-green saver — someone for whom impact and tight exclusions matter as much as returns — will usually feel more at home with an ethics-first specialist where the whole proposition is built around proving its claims.

A more moderate saver — someone who wants the obviously harmful sectors gone but is otherwise happy with a large, well-established manager — may find a broad provider's SRI range fits comfortably, often alongside other options from the same manager.

Neither is the "right" answer in the abstract. It depends on how far you want to go, your timeframe and risk tolerance, and the fee you are willing to pay.

How do you verify a fund's ethical claims yourself?

You do not have to take any provider's marketing at face value. Three independent checks:

1. RIAA certification. Look for the Responsible Investment Certified symbol and confirm it on the RIAA's certified-products listing. Certification means an external assessor has verified the fund is true-to-label.

2. Mindful Money. This independent NZ charity lets you look up your own fund's holdings against specific issues — weapons, fossil fuels, animal welfare and social harm — for free.

3. The fund's own SIPO and PDS. The exclusion list and screening rules that actually bind the manager live here, not in the brochure. If a claim isn't in these documents, it isn't a commitment.

The FMA has been explicit that "integrated financial products" — funds marketed on ethical or ESG features — must disclose those non-financial factors clearly and not overstate them, which is the regulator's guard against greenwashing. ¹ If a fund's holdings don't match its story, that's a red flag worth raising. Our fuller ethical and responsible KiwiSaver guide walks through each of these checks in detail, and how to choose a KiwiSaver fund covers the wider decision.

Frequently asked questions

Is Pathfinder more ethical than Booster? Pathfinder is an ethics-first specialist built entirely around responsible investing, with broader exclusions and an explicit impact and engagement focus. Booster offers a dedicated SRI range within a mainly mainstream business. Whether "more ethical" matters to you depends on whether you want measurable impact and tight screening, or simply want harmful sectors removed. Read each fund's PDS to compare the actual rules.

Are Pathfinder's KiwiSaver funds independently certified? Pathfinder's KiwiSaver funds are certified by the Responsible Investment Association of Australasia (RIAA), meaning an external assessor has verified they are true-to-label. For any Booster SRI fund, confirm the certification status on its current disclosures rather than assuming it. You can check any fund on the RIAA certified-products listing yourself.

Do ethical KiwiSaver funds charge higher fees? Often, yes. Screened, actively managed funds like Pathfinder's Growth fund (around 1.28%–1.37% a year plus a small member fee) sit above low-cost index funds, because screening and engagement cost more to run. ⁴ A higher fee is not automatically bad, but it should be justified by after-fee, after-tax returns over at least five years. Compare like-for-like on Sorted's Smart Investor.

Does going ethical reduce my returns? Not necessarily. Excluding sectors changes how a fund behaves — it may lag the market in some years and beat it in others. Over the long run a well-run screened fund can perform competitively with a mainstream fund of the same risk level, but returns are not guaranteed and past performance is not a reliable indicator of future performance.

How do I check what my "ethical" fund actually holds? Use the independent Mindful Money checker to screen your fund's holdings against issues like weapons and fossil fuels, confirm any RIAA certification on the certified-products listing, and read the fund's SIPO and PDS for the binding exclusion list. If the holdings don't match the marketing, that is a greenwashing red flag.
