Understanding PIE Funds and Their Tax Advantages in New Zealand

If you’re investing in New Zealand, you’ve likely come across the term "PIE fund." PIE stands for Portfolio Investment Entity — a type of investment vehicle that offers significant tax benefits for many Kiwi investors. Whether you’re a first-time investor or looking to optimise your portfolio, understanding how PIE funds work and their tax advantages can help you make smarter decisions.

This guide explains what PIE funds are, how they’re taxed, who benefits most, and how to choose the right one for your situation.

What is a PIE Fund?

A PIE fund is a managed investment fund that’s taxed differently from standard investments. Instead of paying tax on investment income at your marginal tax rate, the fund calculates tax at a rate based on your Prescribed Investor Rate (PIR).

Common types of PIE funds include:

• KiwiSaver funds
• Managed funds (e.g., growth, balanced, income)
• Exchange Traded Funds (ETFs) structured as PIEs
• Term deposit PIEs offered by some banks

Most major New Zealand providers — such as Milford Asset Management, Fisher Funds, Simplicity, and Kiwi Wealth — offer PIE funds.

How PIE Tax Works

Your Prescribed Investor Rate (PIR)

Your PIR determines the tax rate applied to your PIE fund income. It’s based on your income level:

Note: If your income exceeds $70,000, your PIR caps at 28% — which is lower than the top marginal tax rate of 39% for income over $180,000. This is a key advantage for higher earners.

Tax Calculation in a PIE Fund

The fund calculates tax on your investment income (interest, dividends, and capital gains) at your PIR. You don’t need to include this income in your annual tax return — pays the tax on your behalf. This simplifies your tax affairs and reduces the risk of underpayment.

Key Tax Advantages of PIE Funds

• Lower tax rate for higher earners: If your marginal tax rate is 33% or 39%, a PIE fund’s maximum rate of 28% means you keep more of your returns.
• No need to include investment income in your tax return: The fund handles tax, so you avoid tax bills at the end of the year.
• Tax paid from the fund: Your investment returns are net of tax, so you don’t face unexpected tax liabilities.
• Capital gains are taxed at your PIR: Unlike some other investments, capital gains within a PIE fund are taxed at your PIR, not your marginal rate.

Pros and Cons of PIE Funds

Pros

• Tax advantages for investors on higher marginal rates
• Simplified tax reporting
• Professional fund management
• Diversification across assets
• Access to KiwiSaver and managed fund options

Cons

• Management fees can reduce returns (typically 0.3% to 1.5% per year)
• You can’t choose individual investments
• Not beneficial if your PIR is higher than your marginal tax rate (rare but possible)
• Some funds have minimum investment amounts

Who Should Use PIE Funds?

PIE funds are suitable for:

• Higher-income earners (earning over $70,000) who benefit from the 28% cap
• Busy investors who want tax simplicity
• KiwiSaver members — all KiwiSaver funds are PIEs
• Long-term investors looking for diversified, professionally managed exposure

If your income is below $14,000 and your PIR is 10.5%, you may not gain a significant tax advantage, but you still benefit from simplified reporting.

How to Choose a PIE Fund

Follow these steps to select a PIE fund that suits your needs:

Step 1: Check your PIR

Use the Inland Revenue (IRD) website or your previous two years’ income to confirm your PIR. Providing the wrong PIR can result in underpayment and penalties.

Step 2: Compare fund types

Decide whether you want a growth, balanced, or conservative fund. Your risk tolerance and investment timeframe matter.

Step 3: Look at fees

Management fees vary widely. For example, Simplicity’s KiwiSaver fund charges around 0.31% per year, while some active managers charge over 1%. Lower fees mean more of your returns stay in your pocket.

Step 4: Check the provider’s reputation

Research the fund manager’s track record, investment philosophy, and customer service. Look for providers registered with the Financial Markets Authority (FMA).

Step 5: Read the Product Disclosure Statement (PDS)

The PDS contains all key information, including fees, risks, and tax treatment. Always read it before investing.

Comparison of Popular PIE Fund Providers

Here’s a comparison of four well-known New Zealand PIE fund providers:

Key differences: Active funds (Milford, Fisher) aim to outperform the market but charge higher fees. Passive funds (Simplicity) track indexes at lower cost. Kiwi Wealth offers a middle ground with moderate fees and digital access.

Recommendation: If you’re a hands-off investor with a long horizon, Simplicity’s low fees are hard to beat. If you want active management and are comfortable with higher fees, Milford or Fisher may suit you. Always check the latest fees and performance in the PDS.

Tips for Maximising PIE Fund Benefits

• Check your PIR annually: If your income changes, update your PIR with the fund provider to avoid over- or under-paying tax.
• Use PIE funds for non-KiwiSaver investments too: You can invest in PIE managed funds outside KiwiSaver for additional tax advantages.
• Consider a mix of fund types: Diversify across growth and income funds to balance risk and return.
• Review fees regularly: Even small fee differences add up over time. A 0.5% fee difference on a $100,000 investment can cost you thousands over 20 years.

Verdict

PIE funds are an excellent choice for most New Zealand investors, particularly those on higher incomes. The tax advantages — especially the 28% cap for top earners — combined with simplified reporting make them a smart option for building long-term wealth. However, fees vary significantly, so choose a provider that aligns with your goals and budget.

If you’re unsure which fund is right for you, consider speaking with a licensed financial adviser.
