ANZ and other major New Zealand banks, including ASB, BNZ, and Westpac, have raised floating home loan and business interest rates by 0.25% following the Reserve Bank of New Zealand’s decision to increase the official cash rate (OCR). These adjustments affect both new and existing borrowers, reflecting a broader shift in the national lending environment.
Why Major Banks Are Adjusting Floating Rates
The recent wave of rate hikes, led by ANZ and mirrored by ASB, BNZ, and Westpac, follows the Reserve Bank’s move to lift the official cash rate for the first time in over three years. According to an ANZ spokesperson, these adjustments are part of a regular review process that accounts for international market conditions, local economic trends, and the underlying cost of funds.
Banks typically adjust their variable rates based on wholesale rate movements and competitor activity. When the Reserve Bank signals a shift in monetary policy, commercial lenders often realign their interest rates to maintain margins and manage risk. For borrowers, this means the cost of servicing debt on a floating mortgage is rising across the board.
Pro Tip: If you are feeling the pinch, banks like ASB have publicly encouraged customers to reach out early. ASB executive general manager personal banking, Adam Boyd, noted that “interest rate increases can be difficult for many households” and advised borrowers to contact their lender to discuss financial options.
Comparison of Recent Bank Rate Increases
The following table outlines how major lenders have adjusted their variable housing rates in response to the recent market shift:

| Bank | Standard Variable Rate Change |
|---|---|
| ANZ | 5.79% to 6.04% |
| ASB | Increased to 6.04% |
| BNZ | Standard variable to 6.09% |
| Westpac | Increased by 0.25% |
Impact on Savers and Business Borrowers
While homeowners face higher repayments, the environment for savers has shown signs of improvement. ANZ announced that the premium interest rate on its “Serious Saver” account would rise by 0.25% to 1.75% effective August 1. To qualify for the total rate of 1.80%, customers must deposit at least $20 each month and avoid making any withdrawals.
Business owners are also seeing changes to their cost of capital. ANZ confirmed that its term loan floating base rates have moved up from 4.10% to 4.35%. Like home loans, these business rates are subject to ongoing reviews based on the bank’s assessment of wholesale funding costs.
Did you know? Most major banks in New Zealand have synchronized their floating rate increases within a similar 0.25% bracket, showing how closely retail bank pricing tracks with the Reserve Bank’s official cash rate.
Frequently Asked Questions
Why do floating rates change more often than fixed rates?
Floating rates are pegged to the official cash rate and wholesale market conditions, allowing banks to adjust them quickly. Fixed rates are locked in for a specific term, meaning they do not change until the term expires.
What should I do if I cannot afford my mortgage repayments?
Contact your bank immediately. Most lenders have hardship teams and can discuss restructuring your loan, switching to interest-only payments for a period, or extending your loan term to lower monthly obligations.
Are all banks raising rates by the same amount?
While the 0.25% increase is consistent across the major banks mentioned, the specific timing of when these rates take effect varies by institution. Borrowers should check their specific bank’s official notice for their effective date.
