Short-Term Rates Plummet Below 5.8%
This week, several major tier-one New Zealand lenders dropped their 1-year fixed "special" rates below the 5.80% threshold, a move that caught wholesale markets off guard. The repricing reflects an aggressive front-book battle: with mortgage volumes still well below 2021 peaks, ANZ, ASB, BNZ, Westpac, and Kiwibank are all competing intensely for new business and high-quality refinance applications. For borrowers, this is a rare moment where the carded "specials" have closed most of the gap to the negotiated broker pricing seen earlier in the year.
Why Banks Are Discounting Short-Term Specifically
Lenders are concentrating the discount on the 1-year term rather than 2 or 3-year fixed for a strategic reason: the RBNZ is widely expected to cut the Official Cash Rate further over the next 12 months, which would compress floating rates and short-fixed wholesale costs. By offering a sharp 1-year special, the banks lock customers in for just long enough to ride the next leg down — at which point those borrowers will be re-fixing at the lower medium-term rates the banks expect to be carded by then. The economics favour the lender; the choice is whether the economics also favour you.
What This Means for NZ Borrowers Rolling Off Higher Fixed Rates
For NZ homeowners coming off 2022 and 2023 fixed terms (many of which were locked in above 7%), the saving from refixing onto this 1-year sub-5.80% rate is substantial. On a $600,000 loan, the monthly repayment difference between 7.05% and 5.79% is approximately $480 — close to $5,800 of saving over a single 1-year fixed term. For refinancers, several of these specials are also paired with active cashback contributions of 0.50%–0.90% of the loan amount, adding another $3,000–$5,400 to the upfront benefit.
1-Year vs 2-Year vs Split — Which Strategy Wins Now?
Choosing a term in this environment is no longer a default. The 1-year sub-5.80% special is sharp but exposes you to whatever the carded 1-year rate looks like in May 2027. The 2-year fixed (currently sitting around 5.69%–5.89% at most majors) gives more certainty if you believe the OCR-cut cycle stalls. A split between 1-year and floating is increasingly popular for borrowers who want to attack the principal with extra repayments while still capturing the headline short-term special.

How to Capture This Rate Before It Moves
Carded specials of this depth tend to last 2–6 weeks before banks recalibrate. To capture the rate, NZ borrowers need to either (a) be a new-money refinance customer, with documents ready to submit immediately, or (b) be inside the 60-day window where their current bank's rate lock policies can secure the special before settlement. We are submitting applications across ANZ, ASB, BNZ, Westpac, Kiwibank, TSB, SBS, The Co-operative Bank, and the active non-bank panel this week to compare which lender's specific 1-year special wins net of cashback, legal costs, and any clawback on existing cashback received. See the latest carded pricing on our live NZ rates page.
Looking Ahead
Week 21 will likely see the remaining majors either match this 1-year sub-5.80% pricing or differentiate by sharpening the 2 or 3-year term. Either outcome benefits borrowers. The risk to monitor is any unexpected upside surprise in May CPI data, which would slow the RBNZ-cut narrative and could see these front-book specials withdrawn just as quickly as they appeared. If you have a fixed-term roll-off in the next 60 days, this is the window — book a free 15-minute consultation to see which lender wins for your specific scenario.
