The 6-month term deposit is one of the most popular terms in New Zealand — offering a balance between a reasonable rate and short enough lock-up that you’re not committed for too long. Here’s what the major NZ banks and alternative providers are offering in May 2026.
In May 2026, the highest 6-month term deposit rates in NZ are from Heartland Bank and other challenger banks, typically ranging from 4.50–5.20% p.a. The major banks (ANZ, ASB, BNZ, Westpac) tend to offer 4.00–4.80%. All deposits at registered banks up to $100,000 per institution are covered by the Depositor Compensation Scheme.
6-Month Term Deposit Rates — May 2026
Rates are indicative. Always confirm directly with the provider before investing. Rates change frequently.
| Provider | 6-month rate | Min deposit | DCS coverage |
|---|---|---|---|
| Heartland Bank | 5.10–5.20% | $1,000 | ✅ $100,000 |
| Rabobank NZ | 4.90–5.10% | $1,000 | ✅ $100,000 |
| SBS Bank | 4.80–5.00% | $1,000 | ✅ $100,000 |
| Kiwibank | 4.60–4.80% | $1,000 | ✅ $100,000 |
| BNZ | 4.50–4.70% | $2,000 | ✅ $100,000 |
| Westpac | 4.50–4.70% | $1,000 | ✅ $100,000 |
| ASB | 4.40–4.60% | $1,000 | ✅ $100,000 |
| ANZ | 4.40–4.60% | $1,000 | ✅ $100,000 |
Ranges reflect that rates vary by balance tier (some banks offer better rates for $25,000+, $50,000+, or $100,000+).
What to Look For Beyond the Headline Rate
Interest payment frequency:
- Some banks pay interest at maturity (6 months)
- Others offer monthly interest payments — useful for retirees needing regular income
- Monthly payment rates are typically slightly lower than maturity rates
Automatic rollover: If you don’t give instructions before maturity, most banks automatically roll your term deposit into the same term at the current rate (which may be lower). Set a calendar reminder and actively choose your next term.
Early withdrawal penalty: Standard 6-month TDs have a break penalty — typically 30–60 days of interest lost if you exit early. Confirm the break fee before committing.

Depositor Compensation Scheme
Since 1 July 2025, NZ has had a Depositor Compensation Scheme (DCS), established under the Deposit Takers Act 2023 and administered by the Reserve Bank of New Zealand:
- Covers $100,000 per depositor per institution
- Applies to deposits at registered banks and other licensed deposit takers (credit unions, building societies)
- Covers NZD deposits only
- Kiwibank, ANZ, ASB, BNZ, Westpac, Heartland, Rabobank, and SBS all participate
To maximise protection, split amounts over $100,000 across multiple institutions.
How Much Does the Rate Difference Matter?
Example: $50,000 for 6 months
| Rate | Interest earned (6 months) | After tax at 28% PIR |
|---|---|---|
| 4.40% (ANZ/ASB) | $1,100 | $792 |
| 4.80% (Kiwibank) | $1,200 | $864 |
| 5.10% (Heartland) | $1,275 | $918 |
Difference between lowest and highest: $126 after-tax over 6 months.
On $100,000, the gap doubles: $252 after-tax. Meaningful but not life-changing. The higher rate is still worth having if the effort is minimal.
Are Higher-Rate Banks Safe?
In the May 2026 table above, Heartland Bank and Rabobank NZ show the highest 6-month rates. Both are regulated by the RBNZ, hold required capital ratios, and are covered by the Depositor Compensation Scheme up to $100,000.
- Heartland Bank: NZX-listed (HGH), NZ-owned, focused on reverse mortgages, rural, and business lending.
- Rabobank NZ: Subsidiary of Dutch cooperative Rabobank. NZ branch covered by the Depositor Compensation Scheme.
Neither is a shadow bank or non-bank. Both are registered banks under the Reserve Bank of New Zealand Act.
6 Months vs Other Terms
| Term | Typical rate (2026) | Often used for |
|---|---|---|
| 30–90 days | 4.00–4.40% | Emergency fund buffer, very short-term |
| 6 months | 4.40–5.20% | Balancing rate and flexibility |
| 12 months | 4.30–5.00% | Slightly lower in some banks; others higher |
| 2 years | 4.20–4.80% | If you believe rates will fall |
| 3 years | 4.00–4.60% | Longest mainstream term |
In mid-2026, 6-month rates often match or exceed 12-month rates at many banks, a flat or inverted term deposit curve. So 6 months gives the same rate with more flexibility.

Where to check the latest data
Rates, fees and returns change often. Before deciding, check current figures yourself:
- interest.co.nz term deposits (1 to 9 months): tables of current short-term deposit rates.
- interest.co.nz term deposits (1 to 5 years): tables of current longer-term deposit rates.
- interest.co.nz term PIE rates: tables of current term PIE rates.
- The provider's own website: has its current rates, fees and full terms; these change more often than any comparison page.
- Financial Service Providers Register: shows whether a provider is registered to offer financial services in New Zealand.
Frequently Asked Questions
How does a 6-month term compare with other terms? In May 2026, 6-month rates are broadly competitive with longer terms. For most investors, 6 months offers a good balance of rate and flexibility. A rolling 6-month strategy (reinvesting at maturity) has historically captured improving rates as the RBNZ cuts the OCR.
Can I add money to a term deposit during the term? No. Term deposits are fixed — you invest a set amount for a set term. To add more, you’d open a separate term deposit.
What happens if the bank fails? The Depositor Compensation Scheme covers $100,000 per depositor per institution. Amounts above this are general creditors in the bank’s liquidation (rare but possible).
