Westpac Term Deposit Rates

Westpac term deposit rates in New Zealand

Westpac New Zealand is one of the country’s big-four banks and part of the Australian-headquartered Westpac Group. As a full-service retail and business bank with a long history serving New Zealanders — including a long-standing role as the main banker to the New Zealand Government — Westpac operates one of the largest nationwide branch and ATM networks in the country. For savers, that scale usually means a familiar place to park a fixed deposit alongside everyday banking, lending and KiwiSaver services. You can compare Westpac with all the major NZ banks using the table above, which we update daily so you can see where Westpac sits against the rest of the market.

How to read Westpac’s rates table

The rates table above lists Westpac’s advertised annual interest rates against the available terms, typically running from a few months out to several years. Read across each row to match a term length with its rate, and remember that the headline percentage is a per-annum figure rather than the total you would earn over a shorter term. Once you have a term and rate in mind, use our term deposit calculator to estimate your returns before you commit. Always confirm the live figure directly with Westpac, as advertised rates can change between our daily updates.

Interest payment and compounding options

New Zealand banks generally let you choose how often interest is paid — commonly monthly, quarterly, six-monthly, annually, or at maturity — and Westpac typically offers a range of these arrangements. Taking interest as regular income suits those who want cash flow, while leaving it to compound can grow the balance faster over a longer term. The right choice depends on your goals, so ask Westpac which options apply to the specific term and product you are considering.

Minimum deposits and early withdrawal

Term deposits usually have a minimum opening amount, and Westpac sets its own thresholds, so check the current requirement with the bank rather than assuming a figure. Funds are intended to stay locked for the agreed term. If you need to break a Westpac fixed-term deposit early, you may face a reduced interest rate, an adjustment, or a break cost, and notice periods can apply. These conditions vary, so confirm Westpac’s current early-withdrawal terms before opening a deposit.

What drives Westpac’s rate changes

Like its peers, Westpac reviews term deposit rates in response to several forces:

• RBNZ Official Cash Rate: shifts in the OCR and the Reserve Bank’s monetary policy outlook flow through to deposit pricing.
• Competition: how rivals across the big-four and the wider market are pricing their own terms.
• Funding costs: the cost of wholesale and retail funding, including conditions across the broader Westpac Group.
• Economic conditions: inflation, demand for term funding, and the general interest-rate environment.

How Westpac compares

As a big-four bank, Westpac competes on more than headline rate. Existing customers may value the convenience of managing a deposit alongside their other Westpac accounts, the breadth of the branch and digital network, and established service support. Smaller banks sometimes advertise higher rates to attract deposits, so it is worth weighing rate against relationship, accessibility and your own banking setup. Retirees and older savers comparing income options may also find our term deposit rates for seniors guide a useful starting point.

Risks and considerations

Fixed-term deposits offer rate certainty, but a fixed rate means you will not benefit if market rates rise during your term. If inflation outpaces your rate, the real value of your returns can erode. Your money is also locked away, limiting access and ruling out other opportunities during the term. Interest is generally subject to Resident Withholding Tax in New Zealand. None of the above is financial advice — verify all current rates, terms and any deposit-protection arrangements directly with Westpac before investing.
