What is the current floating interest rate?

Current ANZ floating rate as of January 2026

• ANZ’s floating home loan rate is 5.79% p.a. as of January 2026, confirmed on the ANZ official rate page (New Zealand’s largest bank).
• The previous rate was 5.69% before the 0.1% increase.
• Floating rates can change at any time based on market conditions and the Official Cash Rate.

Historical context of ANZ floating rates

• ANZ’s floating rate has moved in line with the Reserve Bank of New Zealand’s OCR adjustments over the past few years.
• In early 2025, the floating rate was around 5.89% before dropping to 5.69% later in the year.
• The January 2026 increase reversed some of that decline.

How floating rates are set

• Banks base floating rates on the OCR plus a margin to cover costs and profit.
• ANZ reviews its floating rate periodically and can adjust without notice.
• Changes are influenced by funding costs, competition, and regulatory requirements.

The pattern: ANZ’s floating rate remains above the level it was at before the recent drop, signalling that the bank sees room to rebuild margins.

Did ANZ increase floating home loan rates 0.1 percent?

Details of the rate increase

• ANZ raised its floating home loan rate by 0.1% in January 2026, as reported by RNZ (New Zealand’s public broadcaster).
• The new rate is 5.79% p.a.
• This follows two variable-rate increases in Australia of 0.25% each in March and May 2026, per ANZ Newsroom (bank’s official media).

Impact on borrowers

• For a $500,000 owner-occupier loan, the 0.1% increase adds roughly $40 per month.
• ANZ’s Australian counterpart said a 0.25% increase added about $80 per month on the same loan size.
• The increase disproportionately affects borrowers with larger mortgages or those already on tight budgets.

Market reaction and expert commentary

• David Cunningham, Chief Executive of Squirrel, told RNZ that the 0.1% increase would generate an estimated $12 million in extra annual profit for ANZ.
• “Borrowers are understandably frustrated,” Cunningham said, “because floating rates are the most flexible but also the most exposed to bank pricing decisions.”
• Competitors like ASB and Westpac have not yet announced matching increases, creating a window for rate-sensitive borrowers to switch.

What this means: The increase is small for individual borrowers but adds up to a significant revenue boost for the bank.

What are the disadvantages of a floating interest rate?

Rate uncertainty and monthly payment variability

• Floating rates expose borrowers to interest rate fluctuations, meaning monthly repayments can rise or fall without warning.
• Unlike fixed rates, there is no certainty about what your payment will be in six months’ time.
• This unpredictability can make budgeting difficult, especially for first-home buyers.

Potential for higher costs during rising rate cycles

• In a rising rate environment, floating rates increase faster than fixed-rate reset periods.
• ANZ’s January 2026 increase is a clear example: floating borrowers absorbed the full 0.1% immediately.
• Over a full year, the extra cost on a $500,000 loan is about $480.

Comparison with fixed-rate stability

• Fixed rates lock in a payment amount for a set term, providing budget certainty.
• However, fixed rates may start higher or lower than floating rates depending on the term.
• The trade-off: flexibility versus predictability. Floating rates allow extra repayments without penalty, but at the cost of rate stability.

The catch: The very flexibility that attracts borrowers can become a liability when rates are on the rise.

What is a floating interest rate?

Definition and key features

• A floating interest rate changes in line with market interest rates, as explained by ANZ (New Zealand’s biggest home lender).
• It is also called a variable rate because it can go up or down at the bank’s discretion.
• Borrowers can make extra repayments without penalty and often have access to a revolving credit facility.

How floating rates differ from fixed rates

• Fixed rates lock in an interest rate for a specific term (e.g., 1 year, 3 years).
• Floating rates are typically higher than the best fixed-rate offers at any given time.
• But floating rates provide the flexibility to pay off the loan faster without break fees.

Typical floating rate products at ANZ

• ANZ offers a floating home loan rate (currently 5.79%) and a Flexible Home Loan rate (5.90%).
• The Flexible Home Loan allows unlimited extra repayments and a redraw facility.
• Both are linked to the same floating rate but the Flexible product has a slightly higher margin.

The implication: Understanding these product features helps borrowers decide which loan structure fits their financial goals.

Which bank has the lowest interest rate in NZ?

Three major banks, one comparison: ANZ’s 5.79% sits above some competitors’ floating rates, but the gap is narrow and can change quickly.

The implication: ANZ is not the cheapest floating option right now. Borrowers should check current offers from at least two other banks before committing.

Current comparative floating rates among major banks

• ASB and BNZ are estimated to offer floating rates around 5.69%, 0.10% lower than ANZ.
• Westpac is around 5.74%.
• These rates are not static – always verify on each bank’s official website.

ANZ’s position relative to competitors

• ANZ’s floating rate is at the higher end of the Big Four banks after the January increase.
• This gives borrowers a reason to shop around or negotiate with ANZ for a better deal.
• ANZ’s overall customer satisfaction ratings (see NZ Review’s analysis) may influence retention.

Factors influencing bank rate choices

• Banks adjust rates based on the OCR, funding costs, and competitive pressure.
• ANZ’s 1H26 cash profit of NZ$1.238 billion (up 2% on the prior half) suggests room to absorb costs without passing them on entirely.
• But the bank chose to increase floating rates, signalling a focus on margin improvement.

The pattern: ANZ’s higher rate puts pressure on customer loyalty, but the bank’s brand strength may still retain borrowers who value convenience.

Timeline of ANZ floating rate changes

• Before January 2026: ANZ floating rate was 5.69% p.a. (RNZ)
• January 2026: ANZ increased floating rate by 0.1% to 5.79% p.a. (RNZ)
• March 2026 (Australia): ANZ raised variable rates by 0.25% (ANZ Newsroom)
• May 2026 (Australia): ANZ raised variable rates by another 0.25% (ANZ Newsroom)
• Ongoing: Borrowers can choose fixed or floating; rate may change again based on OCR and market conditions.

The pattern: The timeline shows a clear sequence of rate increases, with Australian moves hinting at possible further NZ adjustments.

What we know and what’s still unclear

Confirmed facts

• ANZ floating rate is 5.79% as of January 2026 (confirmed by ANZ official site and RNZ).
• Increase of 0.1% occurred in January 2026 (multiple news sources).
• Squirrel CEO David Cunningham estimated $12m extra profit (RNZ).
• ANZ NZ reported cash NPAT of NZ$1.238 billion for the half-year to March 2026 (ANZ Newsroom New Zealand).

What remains unclear

• Whether other banks will follow with similar floating rate increases.
• Exact future direction of the OCR and its impact on floating rates.
• Whether ANZ will adjust rates further in 2026.
• How long the current rate differential between ANZ and competitors will persist.

Expert perspectives

“ANZ’s decision to increase the floating rate will generate an estimated $12 million in additional annual profit.”

— David Cunningham, Chief Executive of Squirrel, in RNZ (New Zealand public broadcaster)

“We continue to review our rates in response to market conditions, funding costs, and the competitive environment.”

— ANZ spokesperson, as quoted on the ANZ official rate page

“For borrowers on floating rates, the key risk is that the bank can increase your rate at any time without needing to explain why.”

— Mortgage adviser, quoted in Stuff (NZ news outlet)

What this means for borrowers

The 0.1% increase is small in isolation but significant in context. ANZ earns an extra $12 million annually from the change, while borrowers with a $500,000 loan pay about $480 more per year. For those who value budget certainty, switching to a fixed rate or refinancing with a competitor offering a lower floating rate could make sense. The trade-off: you lose the flexibility to make extra repayments without penalty. For a borrower in a rising rate cycle, the safest path is to split the loan between fixed and floating, or to negotiate a better floating rate with ANZ directly.

The catch: The fixed-rate option is the safer bet for borrowers prioritizing stability.
