Online-Only Banks in NZ

Online-Only Banks in NZ

Here is the thing most people get wrong about this topic: New Zealand does not actually have a locally owned, digital-only registered bank that is fully up and running. What we have is a group of app-based services that are not banks themselves, plus a handful of established banks that take deposits online with no branch network. That is a different thing, and the difference matters when you are deciding where to put your money.

So this guide covers both. We look at the app-based services, the online savings providers paying some of the better on-call rates in the market, and the everyday accounts at the big banks that now cost nothing per month. Then we get into the part that quietly decides everything: whether your money is covered if the institution fails, and what happens to a joint account when a relationship ends.

How We Researched This Guide

We built this from primary sources rather than press releases. The rate tables come from each deposit taker's own published rates, compiled as at 10 September 2026, with Heartland's own table as at 17 August 2026. Fee details come from each bank's transaction account page. The Depositor Compensation Scheme rules come from the Reserve Bank's own pages, and the relationship property rules are set out in full on legislation.govt.nz under the Property (Relationships) Act 1976.

Two things surprised us. First, all five major banks now offer a $0 monthly fee everyday account with free electronic transactions — the fee war is effectively over, and the remaining charges sit in staff-assisted and branch transactions. Second, Heartland carries a BBB credit rating yet pays a similar rate to banks rated AA- or AA. That is the trade-off worth noticing, and we have flagged it rather than glossed over it.

The Quick Summary (60-Second Version)

If you only read one part of this, read this bit.

• No locally owned, digital-only registered bank is fully operating in New Zealand yet. Emerge says plainly it is not a registered bank, and Dosh has publicly stated it is applying to become one.
• Emerge and Dosh hold customer funds in trust accounts with licensed banks, so Depositor Compensation Scheme cover applies where the money actually sits — not because the app itself is a bank.
• The Depositor Compensation Scheme protects up to $100,000 per depositor, per deposit taker, and it started on 1 July 2025 under the Deposit Takers Act 2023.
• Joint accounts are covered per person, so a couple with $200,000 in a joint account at one bank is fully covered.
• On-call savings rates sit well below term deposit rates. Heartland's Digital Saver paid 2.20% p.a. as at 17 August 2026, against 3.90% for a 12 month term deposit.
• The gap between a 1 year and a 5 year term deposit rate is small — roughly 0.7 to 0.85 of a percentage point — so locking in for five years does not buy much extra yield.

What Actually Exists in New Zealand

Emerge is an app-based money service with personal and business accounts. It states plainly that it is not a registered bank yet. Customer funds are held in a trust account with a licensed bank, and eligible deposits are covered by the Depositor Compensation Scheme up to the scheme limit. Emerge also offers a starter account you can open without a passport or driver licence, with a $5,000 balance limit until you add full ID.

Dosh is an app-based service offering spend, save and borrow. It is not a registered bank either, and customer funds are held at a New Zealand registered bank. Dosh has publicly stated it is applying to the Reserve Bank to become a registered New Zealand bank. Until that happens, you are relying on the arrangement rather than holding a deposit with a bank directly — so check where your money is actually held before assuming the same protection as a bank account.

Everyday Accounts, Savings and Term Deposits

The $0 everyday account is now standard

All five major banks offer a $0 monthly fee everyday account, and electronic transactions are free on all of them. The differences sit in staff-assisted and branch transactions, paper statements, overdrafts and card perks. ANZ's Go account charges $3 per manual staff-assisted withdrawal, waived if you are under 21 on an individual account — but that exemption does not apply to a joint Go account even if one holder is under 21. BNZ's YouMoney lets you hold up to 25 accounts with nicknames, though paper statements cost $1.50 per envelope.

Westpac's Everyday account has no monthly fee, a free eftpos card, and a Debit Mastercard that earns Airpoints. Its unarranged overdraft interest is 19.95% p.a., calculated daily, plus a fee. ASB's Everyday account pays no interest and usually cannot go below $0, but if it does, no fees or interest are charged. Kiwibank's FreeUp charges $3 per branch deposit and $3 per branch withdrawal, with the first deposit each month free and no transaction fees if you are under 19 or over 65. A $0 monthly fee does not mean a free account.

Savings and term deposits

Protection, Ratings and Joint Accounts

The Depositor Compensation Scheme protects depositors if their bank or licensed deposit taker fails, up to $100,000 per depositor, per deposit taker. It started on 1 July 2025 under the Deposit Takers Act 2023 and is administered by the Reserve Bank. Coverage is automatic — you do not need to apply. It covers transaction, savings, notice and term deposit accounts for individuals, businesses and trusts. It does not cover KiwiSaver, bonds, shares, foreign-currency accounts, or losses from frauds or scams.

Credit ratings matter as much as rates. ANZ, ASB, BNZ and Westpac all carry AA- ratings. Kiwibank carries AA. Heartland carries BBB, yet pays a similar rate to the AA- banks. That is the trade-off worth noticing. A higher rate from a non-bank deposit taker reflects a lower credit rating and therefore more risk — General Finance, for example, offered 4.55% for one year and 5.25% for five, against Kiwi Bonds at 2.50% and 3.00%. Worth noting honestly: New Zealand ownership is not automatically safer. BNZ itself nearly collapsed in the late 1980s and was sold to National Australia Bank.

On joint accounts, the law that matters is the Property (Relationships) Act 1976, not the label on the account. Relationship property is divided equally when a relationship ends, and that includes money deposited for shared purposes during the relationship. The single most important practical warning: if you pay an inheritance into a joint account or joint term deposit, it can become so mixed with relationship property that it can no longer be traced, and the whole balance may become relationship property. Each holder can generally access the funds and each can be liable for an overdraft.

Questions You Might Have

Is my money in an app-based service like Emerge or Dosh protected?

The scheme applies to the funds where they are held at a licensed deposit taker, up to the $100,000 limit. But you are relying on the arrangement rather than holding a deposit with a bank directly. Check where your money is actually held before you assume the same protection as a bank account.

What happens to a joint account if we separate?

Relationship property is generally divided equally, and money deposited for shared purposes during the relationship counts as relationship property. Separate property can lose its status if it becomes intermingled. Contact the bank about freezing or restructuring the account rather than leaving it open.

Can we contract out of the 50/50 rule?

Yes. A Contracting Out Agreement under section 21 of the Act lets a couple set their own rules. To be valid, each partner must receive independent legal advice and the agreement must be properly witnessed. It is worth doing properly rather than relying on a handwritten note.

Should I lock in for five years?

Probably not for the yield alone. The gap between a 1 year and a 5 year rate is small — roughly 0.7 to 0.85 of a percentage point — so five years does not buy much extra return for a long commitment. Laddering across several terms usually makes more sense.

Why do online savings providers pay more than my bank?

No branches means lower overheads, and that saving gets passed on as a higher on-call rate. The trade-off is fewer services — you generally cannot walk in for a home loan or get help with a payment problem in person. That is the deal you are accepting.

What Matters Most

The honest answer is that "online-only bank" is a label doing more work than it should in New Zealand. The app-based services are not banks. The online savings providers are banks, just without branches. And the big banks already offer free everyday accounts, so the fee advantage that once defined this category has largely evaporated.

What actually separates a good decision from a bad one is protection and access. Check that your money sits with a licensed deposit taker so the $100,000 limit applies. Then decide how much access you are willing to give up for yield — an on-call rate of 2.20% against a 12 month term deposit at 3.90% is roughly 1.70 percentage points a year, which is the price of being able to reach your money without notice.

And if the account is in two names, sort out what happens to it before you need to. That is the part people leave too late.
