Default KiwiSaver Providers vs Choosing Your Own in NZ (2026): Are You in a Default by Accident?

There are six appointed default KiwiSaver providers in NZ. Many people landed with one by accident at a new job. How default allocation works, and how to take control.

A lot of people never chose their KiwiSaver provider at all. They started a job, ticked a box (or didn't), and the system put them somewhere. If that sounds familiar, you may be with one of the six appointed default providers — and in their default fund — without ever having compared the alternatives.

This article explains who the default providers are in 2026, how people end up with one, the difference between a default provider and a default fund, and how to check and change where you are.

TL;DR: New Zealand has six appointed default KiwiSaver providers for the 2021–2028 term: BNZ, Booster, BT Funds (Westpac), Kiwi Wealth, Simplicity and Smartshares/NZX (SuperLife) ¹. If you didn't pick a scheme when starting a job, you were auto-allocated to one and placed in its low-cost balanced default fund ⁹. You can check via myIR and switch at any time, free ¹⁰.

Who are the appointed KiwiSaver default providers in 2026?

The Government runs a competitive tender every few years and appoints a small panel of "default" providers. New members who don't choose a scheme are spread across this panel. The current term runs from 1 December 2021 to 2028, and there are six appointed default providers ¹:

Being on the default panel does not make a provider "the best" — it means they won a tender to receive auto-allocated members on agreed terms (low fees, a set fund mandate, and a duty to help members engage). Plenty of strong KiwiSaver providers are not on the default list, and you're free to choose any of them. For the wider field, see our KiwiSaver providers list for NZ.

How did you end up with a default provider in the first place?

Most people who are with a default provider got there one of two ways:

• Auto-enrolment at a new job. When you start a new job and you're not already a KiwiSaver member and don't actively choose a scheme, you're automatically allocated to one of the appointed default providers on a roughly even-split basis ⁹.
• Being placed there years ago and never moving. KiwiSaver began in 2007. Many members were defaulted early on, picked a provider by inertia, and have never revisited it.

This matters because a large share of members are not closely engaged with their KiwiSaver. The FMA's 2025 report notes that 30% of working-age members are not contributing, up from about 20% in 2010 ⁸. As at 31 March 2025 there were 3,385,856 KiwiSaver members holding $123.1 billion, with an average balance of about $36,349 ⁷. With balances that size, the provider and fund you sit in is a decision worth making on purpose rather than by accident.

How is a default provider different from a default fund?

These two get muddled constantly, so it's worth separating them.

• A default provider is the company that runs your scheme — one of the six appointed firms above.
• A default fund is the investment option you land in within that scheme if you don't choose one yourself.

When you're auto-allocated, you get both at once: a default provider and its default fund ⁹. Default funds are required to be low-cost balanced funds — a balanced investment mandate that sits between conservative and growth, and they must exclude investments in fossil fuel production and certain weapons ².

A balanced default is a sensible neutral starting point, but it isn't tailored to you. Someone 40 years from retirement and someone buying a first home next year have very different needs, and a one-size default can't reflect that. We cover the fund side in detail in KiwiSaver default funds explained for NZ; this article focuses on the provider side.

What are the pros and cons of staying with your default provider?

Staying put isn't automatically wrong. Default providers are low-cost by design, and a balanced fund is a reasonable middle setting. The question is whether it actually fits your timeframe, not whether it's "bad".

A couple of things worth knowing while you weigh this up:

• The government contribution is easy to miss. From 1 July 2025, the maximum annual government contribution is $260.72 (25 cents per $1 you contribute), down from the previous $521.43; to get the maximum you need to contribute at least $1,042.86 of your own money between 1 July and 30 June ⁴. From the same date, members with annual taxable income over $180,000 are no longer eligible, and eligibility was extended to contributing 16- and 17-year-olds ⁵. Staying in a default provider doesn't affect this — but disengaged members are the ones most likely to fall short.
• Contribution rates are rising. The default minimum employee and employer rate is 3% now, legislated to rise to 3.5% from 1 April 2026 and 4% from 1 April 2028 ⁶.

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.

How do default providers' fees and funds compare?

When the current default funds were set up, they were built to be materially cheaper than the typical balanced fund. At launch the six default funds carried annual fund charges of roughly 0.20%–0.40% p.a., versus an average balanced-fund fee of about 1.26%, and with no fixed annual or monthly membership fee ³. Across the whole KiwiSaver system, total fees as a share of funds under management sat at about 0.7% in the year to 31 March 2025 ⁸.

The key point: a low fee on the default fund doesn't mean that fund is the right type for you, and it doesn't mean the same provider's other funds, or another provider's, wouldn't suit you better. Fees are only one input. To compare across the panel and the wider market on a like-for-like basis, the free Sorted Smart Investor tool lets you line up fees, fund types and charges, and each provider's Product Disclosure Statement sets out the detail. Not every provider in the market is shown above — this is the default panel only.

How do you check which provider you were assigned?

You don't have to guess. Inland Revenue records the provider you were assigned, and you can view it in myIR ¹⁰. To find out where you are:

1. Log in to myIR at ird.govt.nz and open your KiwiSaver details — your current provider is listed there ¹⁰.

2. Check your statements or email. Your provider sends annual statements and usually a welcome pack; the scheme name is on them.

3. Look at the fund name. If it reads like "[Provider] Default Fund" or "Balanced", you may still be sitting in the default option you were placed in.

4. Call the provider or IRD if you're unsure — both can confirm your scheme and fund.

Checking costs nothing and takes a few minutes. It's the first step before deciding whether to do anything at all.

When is actively choosing a provider clearly worth it?

There's no universal answer, but some situations make an active choice more clearly worthwhile for many people:

• A long time until you'll touch the money. People decades from retirement often have the timeframe to consider a more growth-oriented fund than a balanced default — accepting larger short-term swings for potentially higher long-run growth. That's a fund-type question as much as a provider one.
• A first-home purchase coming up. People withdrawing within a year or two may want less volatility than a balanced default, not more.
• You value advice, tools or service that a particular provider offers and your current one doesn't.
• You want a specific investment approach — for example a stronger responsible-investment policy, or index-tracking funds — that your default provider doesn't offer.

A growth fund may suit people with a longer time horizon and higher risk tolerance, though with more short-term volatility — your situation will differ. None of this is a recommendation to switch; it's a list of triggers that make the decision worth thinking through. Our guide to choosing a KiwiSaver fund in NZ walks through the timeframe-and-risk method step by step. Personalised advice works through what actually fits you.

How do you move from a default to a provider you actually chose?

Switching is deliberately straightforward, and members can switch funds or providers at any time at no cost ¹⁰.

One thing to weigh: switching out of a balanced or growth fund right after a market fall locks in that fall. Moving providers is free, but timing the move out of a fund matters. There's more detail in our guide to switching KiwiSaver funds and providers in NZ.

Frequently asked questions

Who are the default KiwiSaver providers in NZ for 2026?

For the current 1 December 2021 to 2028 term there are six appointed default providers: BNZ, Booster, BT Funds (Westpac), Kiwi Wealth, Simplicity and Smartshares/NZX (SuperLife) ¹. The Government appoints them by competitive tender, and new members who don't choose a scheme are spread across the panel.

How do I know if I'm in a default KiwiSaver provider?

Log in to myIR at ird.govt.nz to see your assigned provider, or check your latest statement ¹⁰. If your fund is named something like "Default Fund" or "Balanced" and you don't recall choosing it, you may still be in the default option you were originally placed in.

Is a default KiwiSaver fund a bad choice?

Not necessarily. Default funds are low-cost balanced funds by design ²³, which is a reasonable neutral setting. The issue is fit: a balanced default may be more cautious than someone with decades to retirement wants, or more growth-oriented than someone withdrawing soon wants. It's general, not tailored to you.

Does it cost anything to switch from my default provider?

No. Members can switch funds or providers at any time at no cost ¹⁰. You don't close the old account yourself — the new provider arranges the transfer once you apply.

Will switching providers affect my government contribution?

Switching itself doesn't affect eligibility. The government contribution depends on how much you contribute: from 1 July 2025 you need to contribute at least $1,042.86 of your own money between 1 July and 30 June to receive the maximum $260.72, and members with taxable income over $180,000 are no longer eligible ⁴⁵. Check your contribution rate carries across when you move.

Can I choose a provider that isn't on the default list?

Yes. The default panel is only the six appointed providers; you can choose any KiwiSaver provider in the market ¹. See our KiwiSaver providers list for NZ for the wider field, and always check each scheme's Product Disclosure Statement.
