A high-interest savings account is the right home for your emergency fund and short-term savings. Here’s how NZ’s savings accounts compare in 2026 — including the banks most Kiwis don’t consider.
Best on-call savings rates (May 2026): Heartland Bank Direct Call (4.50%+) and Rabobank Notice Saver (4.40%+) offer the highest rates. Major banks (ANZ, ASB, BNZ, Westpac, Kiwibank) range from 3.50–4.10%. All are covered by the Crown Retail Deposit Guarantee Scheme up to $100,000. For amounts above 90 days, compare term deposits for better rates.

Types of NZ Savings Accounts
On-call / at-call savings accounts
Fully liquid — withdraw any time. Lower interest rate trade-off for flexibility. Best for:
- Emergency fund (needs instant access)
- Saving toward a goal within 3 months
Notice saver accounts
Require advance notice (typically 31 or 32 days) before withdrawal. Higher rate in exchange for reduced liquidity. Best for:
- Emergency fund buffer (if you have a separate liquid emergency fund)
- Saving for a known goal 1–12 months out
Bonus saver accounts
Pay a higher “bonus” interest rate if you meet conditions each month — typically: deposit at least $XX and make no withdrawals. If you break the rule, you earn only the base rate (often much lower).
Common mistake: Missing the bonus condition one month in a year wipes out months of higher interest. Only use bonus saver accounts if you’re confident in meeting conditions every month.
Term deposits (not savings accounts, but often compared)
Lock in your money for a fixed term (30 days to 5 years) for a guaranteed rate — typically higher than on-call savings for terms over 90 days. See: Best Term Deposit Rates NZ.
Why Heartland Bank Pays More
Heartland Bank consistently offers savings rates 0.30–0.70% above the major banks. Why?
- Business model: Heartland is primarily a retail deposit-funded bank. It doesn’t have access to wholesale funding at the same scale as ANZ or ASB, so it competes aggressively on retail deposit rates.
- No branches: Lower cost structure than branch-based banks means more interest to savers.
- NZX-listed: Publicly accountable, RBNZ regulated, Crown Retail Deposit Guarantee Scheme eligible.
- Smaller balance sheet: Higher risk premium than the major 4, reflected in slightly higher rates.
Is Heartland safe? Yes — RBNZ-regulated, NZX-listed, and covered by the Crown Retail Deposit Guarantee Scheme ($100,000 per depositor). Heartland is a registered bank, not a finance company.

Rabobank Notice Saver
Rabobank is the global agricultural banking arm of the Dutch Rabobank Group. In NZ, it operates primarily as an online savings bank for retail depositors.
- RBNZ-regulated, covered by Crown Retail Deposit Guarantee Scheme
- Higher savings rates than major banks — similar to Heartland
- 31-day notice period on their flagship savings account
- No branches in NZ
- Best for: savers who don’t need instant access and want competitive rates
Setting Up a High-Interest Savings Account
- Choose a bank (Heartland or Rabobank for highest rates)
- Apply online — takes 10–15 minutes (NZ ID required)
- Transfer your savings from existing bank
- Set up a regular automatic transfer from your everyday account on payday
Practical tip: Keep your emergency fund at a different bank from your everyday account. The psychological friction of transferring money between banks reduces impulse spending from your emergency fund.
Savings Account vs Term Deposit
| Savings account | Term deposit | |
|---|---|---|
| Access | Anytime (or notice period) | Locked for fixed term |
| Rate | 3.50–4.50% (on-call/notice) | 4.50–5.10% (1-year) |
| Rate change risk | Rate can change anytime | Rate locked for term |
| Best for | Emergency fund, short-term goals | Money you don’t need for 3–24 months |
If you have money you won’t touch for 3+ months, a term deposit almost always pays more than a savings account. Compare: Best Term Deposit Rates NZ.
Tax on Savings Account Interest
Interest earned on NZ savings accounts is taxable as income. Your bank will deduct Resident Withholding Tax (RWT) automatically at source.
Your RWT rate should match your marginal income tax rate:
- Up to $14,000 income: 10.5%
- $14,001–$48,000: 17.5%
- $48,001–$70,000: 30%
- $70,001–$180,000: 33%
- Over $180,000: 39%
Check with your bank that your RWT rate is correct. If it’s set too high, you overpay tax and need to reclaim it in your IR3. If set too low, you underpay and owe IRD at year-end.
Frequently Asked Questions
Should my emergency fund be in a savings account or term deposit? Emergency fund = savings account (on-call). By definition, your emergency fund needs instant access. A notice saver (32 days) may be acceptable if you have a small buffer in your transaction account and can absorb a 32-day wait.
What is the Crown Retail Deposit Guarantee Scheme? From 1 July 2023, NZ introduced a $100,000 per depositor per institution government guarantee for registered banks. If your bank fails, the NZ government guarantees deposits up to $100,000. This applies to ANZ, ASB, BNZ, Westpac, Kiwibank, Heartland, Rabobank, and other RBNZ-registered banks.
Can I have multiple accounts to increase coverage? Yes — the $100,000 limit applies per institution. If you have $200,000 in savings, splitting it between two banks gives you $200,000 covered (assuming $100,000 or less at each).
Is my Heartland money safe? Yes. Heartland Bank is an RBNZ-registered bank (not a finance company — an important distinction) and is covered by the Crown Retail Deposit Guarantee Scheme up to $100,000.
