Lower funding costs trigger price cuts across the board
With ANZ holding the most expensive longer-term fixed rates among the major banks after raising all its fixed mortgage rates in early June — and no rival choosing to follow — Westpac NZ has moved to exploit the gap.
Effective 19 June, the bank trimmed its three, four and five-year special rates by between 0.20% and 0.30% per annum, claiming the lowest advertised fixed mortgage rates across all terms from two to five years among New Zealand's five largest banks.
Geopolitics driving the rate reprieve
The trigger for the cuts is a shift in wholesale funding conditions rather than any move by the Reserve Bank.
"Positive geopolitical developments in the last few weeks have brought our longer-term funding costs down and we're moving quickly to pass savings on to borrowers," said Sarah Hearn, Westpac NZ managing director of product, sustainability, and marketing, in a media release.
Westpac's new special rates now sit at 5.29% p.a. (three years), 5.39% p.a. (four years) and 5.49% p.a. (five years). Westpac already held a joint-low two-year special rate of 5.19% among the major banks, matched by BNZ. Across the five-year term, ANZ's advertised rate of 6.49% now sits a full percentage point above Westpac's equivalent, interest.co.nz reported.
ANZ left exposed as rivals hold firm
The timing is stark. ANZ raised all its fixed mortgage rates in early June, and no other major bank followed — leaving New Zealand's largest mortgage lender facing a likely reassessment of its position.
Financial markets add further urgency to the conversation. The OCR currently sits at 2.25%, and markets expect it to rise by almost 100 basis points over the coming year. That backdrop gives first-home buyers and property investors reason to weigh up locking in at longer terms before the rate cycle turns, even if shorter-term fixed rates remain more popular day-to-day.
A window for borrowers — but context matters
Hearn was candid that the funding shift is limited to the longer end of the curve for now.
"We haven't seen a similar drop in funding costs on shorter lending terms, however we'll keep monitoring wholesale interest rates closely," she said.
Westpac remains slightly off the pace on one-year and 18-month terms, where ASB, BNZ, and others hold sharper rates.
Hearn framed the offering as a genuine choice rather than a one-size-fits-all push.
"While many still prefer the flexibility of fixing for shorter terms, we know that some like the idea of locking in part or all of their lending for longer, especially in times of uncertainty," she said.
That choice may soon become more pressing. With an OCR rise widely anticipated and wholesale funding easing at the long end, the coming weeks could see further repricing across the sector — and mounting pressure on ANZ to respond.
