High-Interest Savings Accounts in NZ Compared

High-Interest Savings Accounts in NZ Compared

A high-interest savings account is not complicated. You put money in, the bank pays you interest, and you can take the money out when you want. The rate is variable, so the bank can move it at any time.

What surprises most people is how little the advertised rate has to do with what you actually earn. The gap between an on-call rate and a 12 month term deposit on the same money is wide — on the Heartland figures we hold, 2.20% on call against 3.90% fixed for a year. That is roughly 1.70 percentage points a year, and it is the price of being able to reach your money without notice.

There is also a safety net that did not exist a few years ago. The Depositor Compensation Scheme, established under the Deposit Takers Act 2023 and run by the Reserve Bank, has covered deposits since 1 July 2025 — up to $100,000 per depositor, per deposit taker.

How We Researched This Guide

We pulled rates straight from the deposit takers. Heartland's savings and term deposit rates are current as at 17 August 2026, the wider term deposit table was compiled as at 10 September 2026, and the everyday account fees come from each bank's own transaction account page. Where a figure carried a date, we kept the date attached, because these rates move often.

Two things stood out. First, all five major banks now offer a $0 monthly fee everyday account with free electronic transactions, so the differences sit in staff-assisted and branch transactions, paper statements and overdraft interest. Second, a BBB-rated bank pays a similar term deposit rate to an AA- bank. Heartland carries a BBB credit rating and still sits near the top of our table. The scheme rules are set out in full on legislation.govt.nz if you want the detail.

The Quick Summary (60-Second Version)

Here is the short version before we get into the detail.

• The Depositor Compensation Scheme covers up to $100,000 per depositor, per deposit taker, automatically, since 1 July 2025.
• Joint account holders are each covered separately, so a couple with $200,000 in one joint account is fully covered.
• On-call savings pay the least. Heartland's Digital Saver and Cash PIE sat at 2.20% as at 17 August 2026.
• Notice accounts sit in between — Heartland's 90 day Notice Saver was at 3.10% on the same date.
• Term deposits pay the most, but the 1 year to 5 year gap is small, roughly 0.7 to 0.85 of a percentage point.
• Foreign-currency accounts are not covered by the scheme, so a US dollar balance at a New Zealand bank gets no protection.

What You Actually Earn on Call

On-call accounts are the simplest product on the shelf. No notice, no conditions, no minimum balance. Kiwibank's Online Call account earns interest from day one with no fees or access restrictions, and the PIE version works the same way but is taxed at your Prescribed Investor Rate, capped at 28%. If your marginal tax rate is higher than that, the PIE is the better wrapper for the identical account.

Rabobank's RaboSaver is on call with no account fees and no minimum balance, and it lets you run up to five sub accounts for separate goals. Interest is calculated daily and paid monthly, with a $5,000,000 maximum. Heartland's Digital Saver allows unlimited withdrawals to one nominated account, with no minimum monthly deposit and no regular fees.

The catch is the rate itself. On-call money earns the least of any deposit product, and that is not an accident — the bank is taking liquidity risk on your behalf. Heartland's Direct Call account, which also has no fees and unlimited withdrawals to one nominated account, sat at 1.75% as at 17 August 2026, below its own Digital Saver.

Notice accounts sit in the middle

Term Deposits and the Shape of the Curve

A term deposit is a loan. You lend the bank a fixed sum for a fixed term at a fixed rate, and the bank knows exactly when it has to give the money back. That certainty is why term deposit rates sit above savings rates across every provider we looked at.

Rates rise with the term, which is the market paying you for tying your money up. What surprised us is how flat that curve is at the long end. The gap between a 1 year and a 5 year rate is only about 0.7 to 0.85 of a percentage point across the institutions in our table. Locking your money away for five years buys you very little extra yield over one year, and you carry the interest rate risk for all of it.

All rates in that table are as at 10 September 2026. Minimum deposits vary a lot — ANZ wants $10,000, ASB $5,000, BNZ and Co-operative Bank $2,000, and Kiwibank, Rabobank and Heartland all start at $1,000.

Rate versus rating

ANZ, ASB, BNZ and Westpac all carry AA- credit ratings. Kiwibank carries AA. Heartland carries BBB, and still pays a similar rate to the AA- banks. That is the trade-off worth noticing: you are not being paid much extra for taking on the lower-rated institution's risk, so the rating deserves as much weight as the rate when you choose.

Early repayment is the trap

Joint Accounts, PIE Accounts and Online-Only Providers

Joint accounts get a better deal under the compensation scheme than many people realise. The $100,000 limit applies per depositor, so each holder of a joint account is covered up to $100,000 in their own right. A couple with $200,000 in a joint account at one bank is fully covered. A trust is treated as a separate depositor, and children's accounts are protected the same way, with the limit applying across accounts held in the child's name.

What the scheme does not cover matters just as much. Foreign-currency accounts are excluded, so money sitting in a US dollar account at a New Zealand bank gets no protection at all. Neither do KiwiSaver, bonds or shares, or losses from frauds and scams.

On the online-only question, New Zealand does not yet have a locally owned, digital-only registered bank that is fully operating. Emerge states plainly that it is not a registered bank yet, and holds customer funds in a trust account with a licensed bank. Dosh is not a registered bank either, and has publicly said it is applying to the Reserve Bank.

Where the protection actually sits

If a service is not a registered bank, the scheme still applies to the funds where they are held at a licensed deposit taker — but you are relying on the arrangement rather than holding a deposit with a bank directly. Check where your money is actually held before assuming the same protection as a bank account. Rabobank is a different case again: a specialist agribusiness bank that also takes retail deposits online, not a neobank.

Questions You Might Have

Is my savings account covered if the bank fails?

Yes, if it is a transaction, savings, notice or term deposit account with a licensed deposit taker. The scheme covers up to $100,000 per depositor, per deposit taker, and coverage is automatic — you do not need to apply. It has applied since 1 July 2025.

Do I need to apply for the Depositor Compensation Scheme?

No. Coverage is automatic if your money is in a protected account with a licensed deposit taker. The scheme is funded by levies on the industry, not by the government out of general tax. You do not need to register or fill in anything.

Should I fix for five years to get the best rate?

Probably not on rate alone. The 1 year to 5 year gap is only about 0.7 to 0.85 of a percentage point across the institutions in our table. Laddering — splitting a lump sum across several terms rather than locking it all into one date — gives you some of the higher rate without tying everything up.

Can I lose my bonus interest by withdrawing?

On a conditional account, yes. Rabobank's PremiumSaver pays a premium rate on balances up to $100,000 provided you increase your month-end balance by at least $50 from the start of the month, excluding interest paid during that month. Miss it, and the minimum rate applies to the whole balance for that month.

Do I earn more with an online-only provider?

Often, yes. No branches means lower overheads, which is why online savings providers can pay a higher on-call rate than a branch-based bank. The trade-off is fewer services — you generally cannot walk in for a home loan or help with a payment problem.

What Matters Most

The rate on the page is not the rate you earn. Conditions, notice periods and early repayment terms all sit between the advertised number and your actual return, and they matter more than a few basis points of headline yield.

Work out what the money is actually for. Money you might need this month belongs on call, even at a lower rate. Money with a known date attached can go into a term deposit, and laddering beats locking everything into one long term for a yield pick-up that is barely there.

Then check the two things people skip: the credit rating behind the rate, and where your money is actually held. With $100,000 of cover per depositor per institution, the scheme does a lot of the heavy lifting — but only if you know which accounts it reaches.
