Simplicity NZ Review — Investment Funds (Not KiwiSaver) 2026

Updated

Simplicity is best known as New Zealand’s lowest-fee KiwiSaver provider. But they also offer non-KiwiSaver investment funds — accessible to any NZ resident, with the same industry-low fees.

Quick answer

Simplicity's investment funds charge 0.10% p.a. — the lowest fee of any diversified investment fund in NZ. The Growth Fund is the flagship: globally diversified, includes NZ shares and bonds. Minimum $1,000 to open, $50/month regular contributions. Not-for-profit structure. No individual fund selection or shares. Best for: cost-focused investors who want a simple, one-decision portfolio.

Simplicity Growth Fund — Detail

The Growth Fund is the most popular non-KiwiSaver fund and appropriate for most long-term investors.

What it holds:

  • Global shares (~55%): passive, tracks MSCI World ex-Australia indices via Vanguard
  • NZ shares (~15%): NZX 50 index
  • Australian shares (~5%): ASX via passive index
  • NZ bonds and cash (~20%): NZ government and corporate bonds
  • International bonds (~5%)

Currency hedging: Simplicity hedges approximately 50–70% of international currency exposure — a moderate hedge position.

Responsible investing: Simplicity excludes companies involved in weapons, tobacco, gambling, and fossil fuel extraction. It’s an ESG-aware fund without being a pure ESG/ethical fund.

Historical performance (approximate, total return after fees):

  • 1-year: varies significantly by market conditions
  • 5-year: approximately 7–9% p.a.
  • 10-year: approximately 8–10% p.a.

Past performance does not predict future returns.

Simplicity’s strengths:

  • Simple decision: choose growth, balanced, or conservative
  • Solid ESG exclusions built in

Simplicity’s limitations:

  • No individual fund customisation (you get what’s in the fund)
  • No NZ/global split control — you can’t adjust geographic allocation
  • No shares or ETF trading
  • $1,000 minimum (higher than Kernel’s $1)
  • Web interface is basic compared to Kernel
  • No international shares fund (global exposure is bundled within the Growth Fund)

Who Should Use Simplicity Investment Funds?

Best for:

  • Cost-focused investors who want to minimise fees above all else
  • Investors comfortable with a simple pre-built allocation
  • Those who don’t need an NZX shares component (Simplicity’s NZ exposure is bundled, not separately accessible)
  • Investors with $5,000+ who find 0.10% vs 0.25% meaningful at their balance

Not ideal for:

  • Investors who want granular control over fund allocation
  • Those who want to also trade individual shares (need a different platform)
  • Investors wanting an S&P 500-only or global-only fund (Simplicity bundles NZ in the Growth Fund)
  • Beginner investors who might struggle with the $1,000 minimum — Kernel’s $1 minimum is better for starting small

How to Open a Simplicity Account

  1. Go to simplicity.kiwi
  2. Click “Open an Account” (investment fund, not KiwiSaver)
  3. Verify identity (NZ driver licence or passport)
  4. Link your bank account
  5. Transfer $1,000 initial investment
  6. Set up a regular monthly contribution ($50 minimum)

The process takes 15–20 minutes. Funds typically appear within 2–3 business days.


Simplicity KiwiSaver vs Simplicity Investment Fund

Both use the same 0.10% fee and same underlying fund structure. The key difference:

  • KiwiSaver: Locked until 65 (exceptions for first home, hardship, serious illness)
  • Investment Fund: Fully accessible — you can sell and withdraw anytime

Many investors use both: Simplicity KiwiSaver for the retirement/employer match/government top-up, and the Simplicity investment fund for additional long-term savings outside the KiwiSaver lock-up.
