Ethical Investing NZ — ESG Funds and Sustainable Options (2026)

Updated

Ethical investing — also called ESG (Environmental, Social, Governance) investing — lets you align your portfolio with your values. In New Zealand, several platforms offer ESG-screened or socially responsible investment options.

Quick answer

For NZ investors wanting ESG exposure, the best options are: Kernel Sustainable Global Fund (0.25%, MSCI World ESG Leaders), Simplicity's standard funds (0.10%, exclusions built in), and InvestNow Foundation Series Sustainable options. All major NZ managed funds exclude some controversial sectors. There's no perfect ethical fund — exclusions vary significantly, so check what each fund actually screens out.

What Does ESG/Ethical Investing Mean?

ESG investing uses criteria beyond financial returns to select investments:

  • Environmental (E): Carbon emissions, climate risk, resource use, pollution
  • Social (S): Labour standards, human rights, community impact, data privacy
  • Governance (G): Board diversity, executive pay, anti-corruption, transparency

Common exclusions in NZ ESG funds:

  • Fossil fuel companies (coal, oil, gas extraction)
  • Weapons manufacturers (especially controversial weapons — cluster bombs, landmines, nuclear)
  • Tobacco producers
  • Gambling companies
  • Adult entertainment

NZ ESG Fund Options

Kernel Sustainable Global Fund

  • Fee: 0.25% p.a.
  • Index: MSCI World ESG Leaders
  • What it holds: ~600 companies with the highest ESG scores within their sector (does not fully exclude any sector — selects best-in-class)
  • Exclusions: Controversial weapons (absolute), tobacco producers (>15% revenue), thermal coal (>5% revenue)
  • Note: MSCI ESG Leaders is a relative approach — some oil companies with good ESG practices may still be included

Simplicity Growth/Balanced/Conservative Funds (Built-in Exclusions)

  • Fee: 0.10% p.a.
  • Exclusions: Fossil fuel extraction, tobacco, weapons (controversial), gambling, adult entertainment
  • Approach: Exclusion-based (removes bad actors rather than best-in-class selection)
  • Note: Simplicity is not marketed primarily as an ESG fund but has strong exclusions built in. The 0.10% fee is significantly lower than dedicated ESG funds.

InvestNow — Foundation Series Sustainability

  • Fee: 0.20% p.a.
  • What it holds: Sustainably screened global equities via Vanguard’s ESG International Shares ETF equivalent
  • Exclusions: Fossil fuels, weapons, tobacco, alcohol, gambling, adult entertainment
  • Note: Check the InvestNow product disclosure for current fund constitution

Smartshares ESG ETFs

  • Smartshares Global ESG Factors ETF (GESF): Tracks global equities with ESG factor tilts
  • Fee: 0.32% p.a.
  • Available via: Sharesies, Tiger Brokers, direct Smartshares account

Best-in-Class vs Exclusion-Based ESG

Two main approaches:

Exclusion-based: Removes companies in specific industries entirely.

  • Example: No oil companies regardless of their environmental practices
  • More intuitive — you know it excludes sector X
  • May exclude large index components, causing tracking error

Best-in-class: Selects companies with the best ESG scores within each sector.

  • Example: The “best” oil company by ESG standards is included; the “worst” is not
  • More diversified — no sector is fully excluded
  • Controversial to some ethically-minded investors (you still own some oil companies)

Kernel’s fund uses best-in-class. Simplicity uses exclusion-based. Neither approach is objectively right — depends on your values.


ESG Performance: Does It Cost Returns?

This is the most-asked question. Short answer: not significantly over the long run, but there are periods of underperformance.

When ESG underperforms:

  • Energy sector bull markets (e.g., 2021–2022 when oil prices surged)
  • ESG funds miss gains in excluded sectors

When ESG outperforms or matches:

  • Extended periods of tech dominance (tech tends to score well on ESG)
  • Governance scandals punish companies ESG screens would have excluded

Long-run data is limited (ESG funds are relatively new). Most academic studies find ESG vs standard index returns are broadly similar over 10+ year periods, with ESG having higher volatility in some periods.


What Most NZ Funds Already Exclude

Even without choosing a specific ESG fund, most mainstream NZ funds have some exclusions. For example:

ProviderBuilt-in exclusions
SimplicityFossil fuels, tobacco, weapons, gambling, adult
Kernel (standard funds)Controversial weapons only
InvestNow Foundation SeriesSome — check each fund’s PDS
Smartshares (standard)Controversial weapons (passive, minimal exclusions)
KiwiSaver funds (most)Controversial weapons (legally required)

NZ KiwiSaver providers are legally prohibited from investing in manufacturers of cluster munitions, anti-personnel mines, biological/chemical weapons, and nuclear weapons. This baseline applies to all KiwiSaver funds.


Greenwashing — What to Watch For

Not all “ESG” or “sustainable” labels are equal. To evaluate a fund:

  1. Read the Product Disclosure Statement (PDS): What specifically is excluded?
  2. Check the responsible investment policy: Is it on their website and detailed?
  3. Look at the actual holdings: Does the fund publish holdings? Any surprises?
  4. Who certifies it? Mindful Money (mindful.money) provides NZ fund analysis and ESG ratings

The Responsible Investment Association of Australasia (RIAA) certifies funds to specific standards. A RIAA-certified fund has met a defined responsible investment standard.

NZ Investor Considerations for ESG

PIR rate advantage still applies: ESG-structured PIE funds in NZ are still taxed at your PIR rate (max 28%) — the same tax advantage as non-ESG PIE funds.

KiwiSaver ESG options:

  • Simplicity KiwiSaver (strong exclusions, 0.31% fee)
  • Kernel KiwiSaver (ESG fund available)
  • Booster Socially Responsible Investment (SRI) fund
  • Generate KiwiSaver (ethical option available)
