All six platforms compared: the table, the trade-offs, and which combination makes sense

Three weeks of platform analysis, brought together in one place. Here is how they stack up and how to think about combining them.

— ✦ —

Over the past three weeks I have covered why the platform decision matters more in New Zealand than almost anywhere else, why PIE fund platforms handle FIF differently from direct investing platforms, and what the trade-offs are for each of the six platforms most NZ investors will encounter. This week I am bringing it together in one place.

The comparison table below covers the five criteria that matter: fees, fund access, FIF handling, custody, and tax reporting. After that, six scenarios that map investor profiles to platform combinations. The goal is not to tell you what to do but to give you a framework for making a deliberate decision rather than defaulting to whatever you signed up for first.

The comparison table

A few notes before the table. Fee structures change, so verify current details directly with each provider. The FIF handling column reflects whether the platform's default structure handles FIF internally at the fund level or passes the obligation to you directly.

Which combination makes sense

Most investors do not need to choose just one platform. The more useful question is what role each platform plays in a portfolio and whether your current setup reflects a deliberate choice or a historical accident.

Scenario 1 — Just starting out, portfolio under $10,000

Sharesies alone

The fee structure works at this size, the experience is the best in market for beginners, and getting started and building the habit matters more than optimising costs. Once your portfolio reaches $10,000–$15,000, reassess.

Scenario 2 — Building a long-term portfolio, $10k–$100k, no interest in stock picking

InvestNow or Kernel as the primary platform

Both handle FIF internally through NZ-domiciled PIE funds, charge no transaction fees on regular contributions, and suit a systematic buy-and-hold approach. Choose InvestNow if you want access to multiple fund managers. Choose Kernel if you prefer a cleaner interface.

Scenario 3 — Building a long-term portfolio and want direct US equity exposure

InvestNow or Kernel + Hatch or Stake

Keep overseas direct holdings below the $50,000 FIF threshold if you want to avoid the FIF obligation, or manage FIF directly if you are comfortable doing so. The two-platform approach is more common than most investors realise.

Scenario 4 — Portfolio above $100,000, comfortable with complexity

InvestNow or Kernel + Interactive Brokers

IBKR's FX conversion costs are significantly lower than retail NZ platforms at this portfolio size. Factor in the additional tax reporting work or the cost of an accountant who can handle it.

Scenario 5 — Already using a bank KiwiSaver and a retail platform, wondering if you're overpaying

Check PIR and KiwiSaver fee first

These two things are where most NZ investors are losing money without knowing it. The PIR threshold changes in April 2025 mean a meaningful proportion of investors are on the wrong rate. The difference between a 0.93% bank fund and a 0.25% low-cost fund compounds to tens of thousands of dollars over a career.

Scenario 6 — Approaching or above the $50,000 FIF threshold

Calculate your FIF position before the next tax year starts

The threshold applies across all your overseas holdings combined, not per platform. If you are near or above it, understand whether FDR or CV gives you a better result for your specific situation. In a flat or down year, CV can be meaningfully lower than FDR.

Four questions worth answering about your current setup

The audit
  • What is your KiwiSaver PIR rate, and is it correct? The April 2025 threshold changes mean a significant proportion of investors are on the wrong rate. It takes 60 seconds to check and your provider will not do it for you.
  • What is your KiwiSaver total annual fee? A 1% fee difference on a $50,000 balance compounds to more than $130,000 over 30 years. Most people do not know what their fund charges.
  • What is the combined cost basis of your overseas holdings? FIF applies to your total overseas holdings at cost across all platforms. Many investors are over the threshold without realising it.
  • Are you using the right FIF calculation method? Most investors default to FDR without checking whether CV would produce a lower result in their specific year.

The investor who understands their platform structure, their FIF position, and their KiwiSaver fee is already ahead of most people in this market. None of it is complicated. It just requires knowing where to look.
