Which banks have the highest interest rates on term deposits?

New Zealand’s term deposit market has tightened considerably since mid-2025, with the best 12-month rates hovering just below 4.00% across major providers. Heartland Bank currently leads among established lenders with a 4.00% rate on 12-month terms, matched only by SBS Bank at the same duration. According to Opes Partners investment analysts, these two institutions are essentially tied for the top spot among mainstream banks.

Top NZ providers

The NZ financial aggregator landscape shows a clear tiering: Heartland and SBS share the top spot at 12 months, while Heartland extends its lead further out on the curve with a 5-year rate of 4.35%. The Co-operative Bank offers 4.70% on 4-year terms, though it’s a smaller institution with different accessibility. MoneyHub’s current compilation shows SBS at 3.55% for 9-month terms and 4.50% for 3-year terms, placing the bank squarely in the competitive mid-range for longer lock-in periods.

Rates above 5%

Some niche providers and credit unions advertise rates exceeding 5.00% p.a., but these typically come with conditions: shorter terms, higher minimums, or membership requirements. InfoChoice aggregates show select offers reaching 5.30%, though these are often from smaller institutions without the same regulatory track record as established banks like SBS. Sorted, New Zealand’s government-backed financial guidance platform, advises investors to verify institutional credibility alongside the rate when comparing offers.

What this means: Investors chasing headline rates above 5% should confirm they meet the eligibility criteria—and verify the institution’s track record—before committing funds.

Which bank is offering the highest term deposit rate?

As of May 2026, Heartland Bank holds the distinction of offering the highest 12-month rate among recognized banks at 4.00% p.a.—a position it shares with SBS Bank at the same term length. However, Heartland pulls ahead at the 3-year mark with 4.15%, compared to SBS’s 4.50% at 36 months. The gap widens further at 5 years: Heartland sits at 4.35% while the market’s true ceiling, according to Canstar’s tracking, reaches 4.60% for 24-month terms at select institutions.

Current market leaders

The Opes Partners comparison snapshot from May 2, 2026 places Heartland and SBS in a dead heat for 12-month products, with both institutions offering exactly 4.00%. For investors willing to lock in longer, Heartland’s 4-year at 4.25% and 5-year at 4.35% represent the best risk-adjusted returns among banks with AA- credit ratings. Interest.co.nz’s data shows AA-rated banks clustering around 3.80% for 12-month terms, making Heartland and SBS outliers in the best possible way.

SBS Bank position

SBS Bank occupies a distinctive niche: it offers Heartland-matching rates at 12 and 18 months while maintaining the flexibility of a lower $1,000 minimum deposit. According to Term Deposit Rates NZ, the bank’s credit rating sits at BBB, and its rates last updated September 10, 2025 on third-party trackers, though the official SBS site lists current rates as of 2026. The bank calculates interest daily with no fees on term investments, per SBS Bank’s investment product page.

What are SBS term deposit rates?

SBS Bank offers term deposits ranging from 1 month to 5 years, with rates that scale upward as you commit for longer periods. The official rates page shows the bank competitive across most standard term lengths, though it trails the market’s peak at shorter durations. The minimum investment of $1,000 makes SBS accessible to first-time investors or those building up a savings buffer gradually.

Standard rates

The SBS rates card as of the official publication shows 3.75% for 12-month terms, 4.00% for 18 months, 4.20% for 24 months, and 4.50% for 36 months. These figures align closely with Heartland Bank’s offerings at matching durations, though Heartland edges ahead at the 5-year mark with 4.35% versus the market’s upper reaches. MoneyHub lists the same 36-month figure of 4.50% for SBS, confirming consistency across major aggregators.

Term lengths 1 month to 5 years

The SBS term investment range spans the full spectrum of investor preferences: short-term options for liquidity needs, medium-term for balanced growth, and long-term locks for maximising yield. Interest.co.nz’s long-term rate table corroborates SBS’s 12-month at 3.75%, 18-month at 4.00%, 24-month at 4.20%, and 36-month at 4.50%. Heartland’s advantage emerges most clearly in the 4-year (4.25%) and 5-year (4.35%) brackets, where SBS’s published rates don’t extend in the same way.

The implication: SBS publishes rates only up to 36 months, leaving a gap that Heartland fills at the 4-year and 5-year marks. Investors seeking longer lock-in periods may need to look elsewhere or accept rolling over at whatever rates SBS publishes then.

SBS term deposit rates calculator

While SBS Bank does not publish a dedicated online calculator on its rates page, investors can estimate returns using third-party tools. An ASB term deposit calculator provides a template for similar calculations: multiply the principal by the annual rate and the fraction of the year represented by your term length. For example, a $10,000 deposit at 3.75% for 12 months yields $375 in interest. Those calculating mortgage costs in New Zealand can also use the mortgage repayment calculator for broader financial planning alongside term deposit investments.

SBS term deposit rates for seniors

New Zealand’s major banks, including SBS Bank, do not publish explicit senior-specific term deposit rates. Research across Canstar, Opes Partners, and official bank channels found no age-based rate tiers for SBS term investments. This finding aligns with the broader market: most NZ institutions apply standard rates regardless of investor age, though eligibility for PIE (Portfolio Investment Entity) accounts may offer tax advantages for lower-income seniors.

Senior-specific offers

Canstar confirms that standard term deposit rates apply across age groups for major banks, with no documented senior discounts for SBS or its primary competitors. Some smaller credit unions and community banks occasionally offer promotional rates targeting senior members, but these are not widespread and typically require membership criteria beyond age alone.

NZ seniors rates

The absence of senior-specific rates does not mean older investors lack advantages. A lower minimum deposit requirement disproportionately benefits retirees who may be working with smaller lump sums. SBS’s $1,000 floor means retirees can access competitive mid-market rates without the $10,000 minimum ANZ requires. Additionally, PIE accounts available through most banks—including SBS—offer a lower tax rate (28% versus the marginal rate) that benefits seniors in lower income brackets.

What this means: Seniors should focus on the universal advantages SBS offers—low entry point, daily interest calculation, and no fees—rather than expecting age-based rate bumps that don’t exist in the NZ market.

How do SBS term deposit rates compare in New Zealand?

SBS Bank sits firmly in the competitive mid-market for New Zealand term deposits, matching or slightly trailing Heartland Bank at most standard term lengths while maintaining one of the lowest entry barriers in the market. The bank’s 12-month rate of 3.75% ties with ASB Bank and trails only Heartland’s 4.00% among major providers. At longer terms, SBS’s 36-month rate of 4.50% actually exceeds Heartland’s published 4.15% at the same duration, though Heartland publishes competitive rates up to 5 years where SBS does not.

Direct comparisons

Across the major banks, SBS holds its own: ASB matches at 3.75% for 12 months, TSB edges ahead at 3.90% for 12-month terms, and Kiwibank maintains comparable minimums at $1,000. Westpac requires $5,000 minimum and offers lower short-term rates, making SBS the more accessible option for smaller investors despite marginally lower published rates. The Co-operative Bank offers standout long-term rates (4.70% for 4 years) but lacks the branch accessibility of larger institutions.
