Comparing High‑Interest Savings and Term Deposit Rates in New Zealand — 2025
Did you know some term deposits in New Zealand exceed 4% annual interest in 2025? This guide clarifies what those headline rates actually indicate, how on‑call, notice and fixed‑term products differ, and gives practical steps to compare returns, access rules, tax treatment and deposit protection so you can make well‑informed decisions.
What “high interest” actually means in 2025
Headline rates are only a starting point — they don’t tell the full story. In 2025, a number of longer‑term term deposits at major banks are being advertised just above 4% per annum, while certain on‑call savings products are offering competitive gross rates with full daily access. However, effective returns depend on compounding frequency, tax settings and early withdrawal rules. Knowing these factors lets you compare products on an equal basis.
Main product types and how they balance returns and access
- On‑call (no notice) accounts
- Provide immediate access to funds and accrue interest daily.
- Suitable for emergency savings or money you need frequently.
-
Some specialist on‑call accounts in 2025 have delivered notably higher rates than ordinary everyday accounts while keeping liquidity.
- Notice saver accounts
- Require advance notice (commonly 32–90 days) before withdrawals.
- Sit between fully liquid accounts and fixed term deposits on the yield/liquidity spectrum.
-
Typically offer higher rates than no‑notice accounts, with levels differing by notice period.
- Term deposits (fixed‑term)
- Lock funds for a specified period (from around 30 days up to five years).
- Generally pay more for longer terms; very short terms usually yield less than multi‑year terms.
- Early withdrawal normally reduces or cancels interest payments.
Current market snapshot (what to expect in 2025)
- Term deposits: For multi‑year terms, these are among the highest straightforward risk‑free returns in the deposit market, with some major banks offering slightly above 4% in 2025. Shorter terms pay noticeably less.
- On‑call alternatives: Certain on‑call accounts have been competitive in 2025; for instance, a named on‑call product offered a gross rate of about 3.25% (as of mid‑April 2025) while providing daily liquidity and monthly payouts.
- Notice saver accounts: Providers have tended to price notice saver rates between on‑call and fixed‑term levels, with actual ranges depending on the notice length.

How compounding and payment frequency change effective return
Advertised rates may be shown as “interest at maturity” or as a simple annual rate. Two main factors alter what you actually receive:
- Compounding frequency: Daily or monthly compounding raises the effective annual yield versus interest only paid at maturity.
- Payment timing: Interest paid monthly or quarterly allows earlier reinvestment of earnings, improving effective returns compared with a lump sum at maturity.
Practical tip: Request the effective annual rate (EAR) from providers or use an online calculator to compare yields on a like‑for‑like basis.
Tax treatment and product structure
- PIEs (Portfolio Investment Entities): Some savings products are structured as PIEs, which can reduce tax on returns for many savers depending on their income. PIE tax treatment can have a material effect on after‑tax yields.
- Personal tax: Interest earned outside PIE structures is typically taxed at your marginal rate. When comparing options, model after‑tax returns for your tax bracket rather than relying only on headline gross rates.
Access rules, penalties and practical considerations
- Early withdrawal penalties: With term deposits, pulling funds out before maturity commonly leads to reduced interest or no interest for the period the funds were held. Notice saver accounts generally allow withdrawals after the notice period without penalty.
- Minimum deposits and fees: Many term deposits and some higher‑rate savings products require minimum deposit amounts (often in the low‑thousands) and may have account fees or conditions. Confirm these before locking in funds.
- Discretionary rates: Banks sometimes offer higher discretionary rates for larger deposits or special arrangements; always check whether a quoted rate is standard or discretionary and how long it applies.
Safety and deposit protection (important 2025 update)
From 1 July 2025 New Zealand’s Deposit Compensation Scheme became active for eligible deposits at participating banks and authorised non‑bank financial institutions. Key points to check:
- Coverage: Verify whether your provider and specific product are eligible and what the insured limit is for each depositor and account type.
- Conditions and exclusions: Some investment products or non‑deposit assets may not be covered. Read scheme rules and provider disclosures carefully.
Before placing sizable sums, confirm coverage and any applicable caps or exclusions with the provider.
Practical checklist for comparing accounts and term deposits
- Compare effective yields (EAR), not just headline rates.
- Confirm compounding frequency and interest payment dates.
- Check whether the product is PIE‑structured and model after‑tax yields.
- Ask about minimum balances, fees, and whether rates are discretionary or promotional.
- Understand access rules and early‑withdrawal consequences.
- Verify eligibility and limits under the Deposit Compensation Scheme.
- Consider diversifying across account types and term lengths to balance liquidity with returns.
Which product suits different needs
- If you need full daily access and prioritise liquidity: look at competitive on‑call accounts with daily withdrawals and monthly interest payouts.
- If you can plan withdrawals and want better returns than a standard savings account: notice saver accounts with a set notice period can be a practical middle ground.
- If you have funds you can lock away for months or years: term deposits generally offer the highest straightforward returns, with longer terms typically paying more.
Always weigh tax, compounding, access rules and deposit insurance before deciding.
Scenario planning and diversification
- Laddering term deposits: Stagger maturities across different terms to create regular access points while benefiting from higher rates on longer terms.
- Mix account types: Keep an emergency fund in a liquid on‑call account, use notice saver accounts for planned expenses, and allocate surplus funds to term deposits to lift yields.
- Revisit decisions: Rates and protection frameworks change; review your allocations periodically, particularly around regulatory or market shifts such as the 2025 deposit protection update.
Final considerations
Comparing high‑interest savings and term deposits in New Zealand in 2025 means looking beyond headline rates. Assess effective yield, tax treatment, access restrictions, minimums and deposit protection. Use a systematic checklist and consider diversifying across product types and maturities to align with your cash‑flow needs and risk tolerance.
