Westpac NZ Review — Banking Products Compared

Westpac NZ Review — Banking Products Compared

Westpac New Zealand is one of the four Australian-owned banks that dominate our market. It sits alongside ANZ, ASB and BNZ, all of them carrying AA- credit ratings, all of them wholly owned from across the Tasman. That matters less than you might think for day-to-day banking, but it matters a lot when you start comparing who pays what on deposits.

Here is the thing that surprised us most while putting this together. Westpac's everyday account is genuinely fee-free, and its Debit Mastercard is the only Airpoints-earning debit card in the country. But the same bank charges 19.95 per cent a year on an unarranged overdraft and has no listed minimum for a term deposit in the figures we hold, while Kiwibank and Rabobank both start at $1,000.

So Westpac is a mixed bag. Strong on everyday banking and card perks, unremarkable on savings rates, and worth understanding properly before you move your money across.

How We Researched This Guide

We built this from primary sources only. That means each bank's own transaction account page, the rate tables published by the deposit takers themselves, and the Reserve Bank's register of registered banks. Our term deposit figures were compiled as at 10 September 2026, and Heartland's own table was taken as at 17 August 2026. Every rate below carries its date because these move constantly.

Two things stood out. First, all five major banks now offer a $0 monthly fee everyday account with free electronic transactions, so the old fee comparison is largely dead. The real differences sit in staff-assisted transactions, paper statements and overdraft interest. Second, the Depositor Compensation Scheme only started on 1 July 2025, is capped at $100,000 per depositor per deposit taker, and is established under the Deposit Takers Act 2023. Plenty of people still do not know it exists.

The Quick Summary (60-Second Version)

Six things worth knowing before you open or move an account:

• Westpac's Everyday account has a $0 monthly fee and no electronic transaction fees, and the Debit Mastercard earns Airpoints with no annual fee.
• Unarranged overdraft interest is 19.95 per cent a year, charged daily, plus a fee — the most expensive thing on the account.
• Fee exemptions exist for over 65s, superannuitants and under 19s, but service fees still apply.
• Westpac's 1 year term deposit sits at 3.90 per cent as at 10 September 2026 — matched by ANZ, ASB and Heartland, and beaten by BNZ, Kiwibank and Rabobank.
• Rabobank pays 4.90 per cent over 5 years, the top of our table, against Westpac's 4.70 per cent at that term.
• Your money is covered up to $100,000 per depositor per bank under the Depositor Compensation Scheme, automatically.

Everyday Banking: Where Westpac Actually Wins

The Everyday account is the strongest part of the Westpac offer. No monthly fee, no electronic transaction fees, a free EFTPOS card and a Debit Mastercard that earns Airpoints with no annual fee. Westpac describes it as the only Airpoints-earning Debit Mastercard in New Zealand, and we have not found one to contradict that.

The catch is everything that is not electronic. Unarranged overdraft interest runs at 19.95 per cent a year, calculated daily, plus an unarranged overdraft fee on top. That is the number to watch if your balance gets tight before payday. Fee exemptions are available for customers aged 65 and over, superannuitants and under 19s, though service fees still apply even then.

How the big five compare on everyday accounts

Savings and Term Deposits: Where Westpac Is Ordinary

This is the weaker half of the Westpac story. On term deposits, Westpac's 6 month rate of 3.45 per cent as at 10 September 2026 is the lowest in our table, below ANZ, ASB, BNZ, Kiwibank, Rabobank, Heartland and Co-operative Bank. Its 1 year rate of 3.90 per cent is matched by ANZ, ASB and Heartland but beaten by BNZ and Rabobank at 4.05 per cent and Kiwibank at 4.00 per cent. Over 2 years, Westpac's 4.30 per cent is competitive without leading.

The shape of the whole market is worth understanding. Rates rise with the term, which is the market paying you for tying money up. But the gap between 1 year and 5 years is small — roughly 0.7 to 0.85 of a percentage point across the institutions above. Locking in for five years does not buy you much extra yield, and it costs you access.

What the rates actually look like

Three things to hold alongside those numbers. Minimum deposits differ sharply — ANZ wants $10,000, ASB $5,000, BNZ $2,000, while Kiwibank, Rabobank and Heartland all start at $1,000. Credit ratings differ too: the big four carry AA-, Kiwibank carries AA, and Heartland carries BBB. And early repayment is not guaranteed. If a bank agrees to let you break a term deposit early, the rate may be reduced, so the money is less accessible than it looks.

Joint Accounts, Protection and the Fine Print

The Depositor Compensation Scheme is the single most useful piece of consumer protection to arrive in years. It started on 1 July 2025, is administered by the Reserve Bank, and is funded by levies on the industry rather than general tax. Coverage is automatic — you do not apply. It covers transaction, savings, notice and term deposit accounts, and it covers individuals, businesses and trusts. It does not cover KiwiSaver, bonds, shares, foreign-currency accounts, or losses from fraud and scams.

The joint account rule catches people out in a good way. The limit applies per depositor, so a couple with $200,000 in a joint account at one bank is fully covered — each holds $100,000 in their own right. Trusts count as separate depositors too, so a sole trustee can be covered up to $100,000 on the trust's behalf.

What the scheme does not fix is relationship property law. That runs on the Property (Relationships) Act 1976, not the label on the account. Relationship property is generally split 50/50 when a relationship ends, and the family home counts regardless of when or by whom it was bought. Inheritance and gifts start as separate property, but here is the trap: pay an inheritance into a joint account or joint term deposit and it can become so mixed with relationship property that it can no longer be traced. The whole balance can then be treated as relationship property.

Questions You Might Have

Is Westpac a safe place to keep my savings?

Westpac New Zealand is wholly owned by Westpac Banking Corporation in Sydney and carries an AA- credit rating. Beyond that, the Depositor Compensation Scheme protects up to $100,000 per depositor, per deposit taker, automatically. That covers transaction, savings, notice and term deposit accounts.

Why is Westpac's 6 month term deposit rate lower than everyone else's?

We do not know their internal reasoning, but the pattern is clear in the table: at 3.45 per cent as at 10 September 2026, Westpac sits below every other institution we track at that term. If you want a 6 month deposit, Rabobank at 3.65 per cent and Co-operative Bank at 3.60 per cent both pay more.

Does the Airpoints Debit Mastercard really have no annual fee?

Yes, according to Westpac's own account page. There is no annual fee on the Debit Mastercard and it earns Airpoints. Westpac describes it as the only Airpoints-earning Debit Mastercard in New Zealand, which makes it the standout feature of the Everyday account.

What happens if I go into an unarranged overdraft?

You pay 19.95 per cent a year, calculated daily, plus an unarranged overdraft fee. That is the most expensive part of the Everyday account by a wide margin. Fee exemptions for over 65s, superannuitants and under 19s do not remove service fees.

Should I split a lump sum across several term deposits?

Many people do exactly that, and it is a sensible approach. Rather than locking everything into one maturity date, you spread it across several terms so money comes free at intervals. It also keeps each deposit under the $100,000 compensation limit if you hold large balances.

What Matters Most

Westpac is a perfectly good everyday bank with one genuinely distinctive feature — that Airpoints-earning debit card with no annual fee. If you bank online, never go into overdraft and want Airpoints without paying for a credit card, the Everyday account does the job.

But do not assume the same bank is the right home for your savings. Westpac's 6 month term deposit rate is the lowest in our table, and its 1 year rate is matched or beaten by four other institutions. The gap between a 1 year and a 5 year rate is under a percentage point anyway, so there is little reward for locking money away for years.

Check where your money is protected, check the minimum deposit, and check the early repayment terms before you commit. The rate on the poster is rarely the whole story.
