Wellington, 29 October 2025 — On Wednesday, TSB Bank shook up New Zealand’s mortgage market by cutting its one-year fixed mortgage rate to 4.39% per annum, making it the lowest among the major banks in the country. The move comes just weeks after the Reserve Bank of New Zealand (RBNZ) slashed the official cash rate (OCR) by 50 basis points, triggering a wave of rate adjustments across the banking sector.
TSB Undercuts Major Banks with Competitive Rate
Previously set at 4.49%, TSB’s new rate represents a 10-basis-point reduction and is available to borrowers with a minimum 20% deposit. The bank’s latest decision positions it slightly ahead of competitors like ANZ, ASB, Westpac, and BNZ, all of which currently offer 4.49% for one-year fixed mortgages.
Penny Burgess, TSB’s General Manager of Customer Delivery, emphasized that the rate cut was designed to support New Zealanders amid rising financial pressures.
“With the cost of living continuing to stretch household budgets, we know many Kiwis are looking for ways to ease financial pressure,” Burgess said. “As a community-owned bank, we’re here to support our customers and help them keep more money in their pockets.”
Cost-of-Living Pressures Driving Rate Changes
The latest OCR cut from the Reserve Bank has played a pivotal role in driving mortgage competition. Earlier this month, most major banks reduced their floating mortgage rates in response to the monetary policy decision.
Economists suggest that this trend could continue as the RBNZ signals further easing ahead of its next official cash rate decision scheduled for November 26. With inflation showing early signs of cooling, lenders are expected to pass on additional savings to consumers in the coming months.
Financial analyst Gareth Kiernan from Infometrics noted that TSB’s proactive move could spur further competition across the mortgage market.
“Smaller banks like TSB are using sharper rates to attract new customers, especially those refinancing or purchasing their first homes. This competition benefits borrowers who can now secure historically low one-year terms,” Kiernan explained.
What It Means for Borrowers
For an average homeowner with a $600,000 mortgage, the new 4.39% rate could mean savings of around $600 annually compared to a 4.49% rate, depending on repayment structure. While that may seem modest, in the current economic climate, every fraction counts.
Mortgage brokers advise borrowers to review their fixed-term options carefully, as the interest-rate environment remains uncertain. Locking in a one-year fixed term may be ideal for those anticipating further rate cuts in early 2026.
The Bigger Picture: Economic Outlook
New Zealand’s housing market has shown early signs of recovery after a two-year slump, driven by falling rates and stronger migration trends. Lower borrowing costs are expected to boost demand, particularly among first-time buyers who have struggled with affordability.
At the same time, the RBNZ continues to balance inflation control with growth support. While consumer prices have softened, housing affordability remains a critical concern.
Industry observers believe TSB’s decision could be a signal of confidence in the stability of the economy going into 2026.
“This move isn’t just about competition—it reflects optimism that rate stability will return,” said economist Sarah Thomason of KiwiBank Research. “Banks are positioning themselves for a rebound in mortgage demand as economic conditions improve.”
What to Expect Next
All eyes are now on Wednesday’s mortgage market trends and how larger banks will respond. If competitors follow TSB’s lead, New Zealand could see a brief rate war among lenders seeking to capture a larger share of borrowers ahead of the summer home-buying season.
The Reserve Bank’s November policy update will likely determine whether these low rates are sustainable or a temporary boost before a potential rebound in 2026.
Final Thoughts
The latest Wednesday update from TSB Bank highlights a positive shift for homeowners and prospective buyers, as competition pushes borrowing costs lower. With the next RBNZ rate decision just weeks away, mortgage holders may want to keep a close eye on upcoming announcements for further opportunities to save.
