Mortgage Rates Comparison NZ: Latest and Best Deals

New Zealand’s mortgage market has shifted dramatically since those November 2023 peaks hit 7.35% for a 1-year fixed rate. With the Reserve Bank cutting the Official Cash Rate by 50 basis points in April 2026, borrowers now have a window of opportunity — but only if they know where to look. This guide walks you through the current lowest rates from ANZ to Kiwibank, the tools that actually help you compare them, and what bank economists are projecting through 2026.

Five platforms dominate the mortgage comparison landscape in New Zealand, each serving a distinct role in the borrowing decision.

What are the latest mortgage rates in NZ?

The big four banks — ANZ, ASB, BNZ, and Westpac — control 85% of New Zealand’s mortgage market, according to Reserve Bank lending data. Their rate decisions set the floor for the entire market. As of late April 2026, ANZ offers the lowest 1-year fixed rate at 5.19% (Interest.co.nz), while Kiwibank leads short-term borrowers with a 6-month fixed at 5.39% (Kiwibank Official).

Daily updates from top sites

Interest.co.nz’s calculator pulls rates from more than 10 NZ banks and updates daily, making it the most visited comparison destination with 1.2 million monthly users. Canstar NZ tracks BNZ as the lowest for 3-year fixed at 5.59% as of 2026-04-30, while Stuff.co.nz’s comparison tool shows the average 5-year fixed rate sitting at 5.89%.

Bank-specific rates overview

Westpac’s 2-year fixed rate stands at 5.49% for owner-occupiers with at least 20% equity (Westpac NZ). TSB Bank offers the lowest investor rate at 5.69% for 1-year fixed (TSB Bank), while SBS Bank provides rates approximately 0.1% lower for rural properties (SBS Bank). Regional variations run 0.15–0.2% higher in Auckland due to demand pressure, according to NZ Herald reporting.

The implication: Major bank rates cluster tightly between 5.19% and 5.89% across common terms, but smaller and regional lenders frequently offer discounts the big four don’t match.

How to use a mortgage rates comparison NZ calculator?

Online calculators transform the rate-shopping process from a time-consuming branch visit into a 10-minute desk comparison. MoneyHub’s calculator goes beyond simple rate comparison by factoring in fees over a 30-year term, showing the true cost of a mortgage rather than just the interest rate. Sorted.org.nz’s government-backed tool compares floating and fixed rates side-by-side.

Top calculator tools

Interest.co.nz’s mortgage rate calculator handles the most common comparison task: finding the cheapest rate across terms and banks. Canstar’s break fee calculator addresses the refinancing question: will the switching savings exceed the exit costs? ANZ’s own refix calculator estimates monthly savings at $200 for borrowers moving to a lower rate.

Step-by-step comparison process

• Input loan amount, term, and equity percentage
• Select fixed vs floating vs split options
• Compare total cost including fees over your loan term
• Check break fees if you’re exiting a current mortgage
• Verify rates are current — some calculators update less frequently than advertised

The pattern: Calculators work best for fixed-rate comparisons where lender fees are known. Floating rate comparisons are less precise because those products change more frequently.

What is the best mortgage rates comparison in NZ?

No single platform wins on every dimension — the “best” depends on what stage of your borrowing decision you’re in. mortgages.co.nz wins for quick online comparison when you need current rates fast. squirrel.co.nz provides expert mortgage advice alongside rates, which matters if your situation involves non-standard criteria like investment properties or business lending. Canstar NZ works best as a one-stop shop for independent rate rankings and award-winning products.

Here is how the five platforms stack up across the features that matter most to borrowers.

Pros and cons of each

The trade-off across these platforms is between rate accuracy and guidance depth. Pure aggregation sites like mortgages.co.nz and mortgagerates.co.nz prioritize speed and comprehensiveness. Advisor-centric platforms like squirrel.co.nz sacrifice some update frequency for contextual advice that accounts for your full financial picture. Canstar occupies a middle position with independent rankings that let you sort by specific criteria without requiring broker-level expertise.

The catch: All five platforms rely on bank-provided data, meaning they catch official rate changes but may not reflect the negotiated rates available to borrowers with strong equity positions or existing customer relationships.

What is the NZ mortgage interest rates forecast for 2026?

Bank economists broadly agree that New Zealand mortgage rates will continue falling through 2026, driven by the RBNZ’s easing cycle. The Reserve Bank’s April 2026 monetary policy statement cut the OCR by 50 basis points to 3.75% — the first reduction since 2020 — signaling further cuts ahead. Kiwibank economists project the OCR will reach 3.25% by Q3 2026, pushing fixed rates below 5% (Kiwibank Research).

Forecast trends

S&P Global’s mortgage outlook analysis aggregates forecasts from five major banks, projecting rates will settle in the 4.8–5.2% range by December 2026. ANZ’s research team forecasts the 1-year fixed rate averaging 5.10% by end-2026 (ANZ NZ Research). The consensus point: borrowers who lock in now at 5.19–5.59% will likely see better deals emerge as the year progresses, but waiting carries the risk of OCR hikes if inflation resurges.

“We expect further OCR cuts to support economic recovery, bringing fixed rates under 5% by year-end,” said Jarrod Kerr, Kiwibank Chief Economist. “Mortgage rates have fallen sharply since 2023 peaks, but affordability remains stretched,” the RBNZ Governor noted in the April MPS statement.

Factors influencing rates

The RBNZ introduced Loan-to-Value Ratio restrictions in 2013 to cool the housing market, with the current limit set at 80% equity for owner-occupiers without requiring lenders mortgage insurance (RBNZ LVR restrictions). The Debt-to-Income ratio cap of 6x income, implemented July 1, 2025 (RBNZ DTI restrictions), limits how much borrowers can take on relative to earnings, effectively capping demand even as rates fall.

What are floating mortgage rates in NZ?

Floating rates in New Zealand function as the market’s most responsive product, changing monthly rather than being locked in for a fixed term. ASB Bank currently offers a floating rate of 6.24% as of May 1, 2026 (ASB Bank), which runs 1.05% above ANZ’s best 1-year fixed rate of 5.19%. Sorted.org.nz’s comparison tool confirms floating rates typically sit 0.8–1.0% higher than the shortest fixed terms.

Current floating rates

Investor rates run 0.3–0.5% higher than owner-occupier rates across all terms, according to Sorted.org.nz guidance. This premium reflects higher perceived risk and regulatory requirements targeting investor activity. For owner-occupiers with stable income, floating makes sense during rate-declining environments when you expect to refix at lower rates within 6–12 months — but the flexibility comes at that 1%+ premium cost.

Comparison to fixed

The historical context matters here. The lowest-ever 1-year fixed rate was 2.79% in November 2021 during COVID stimulus (Interest.co.nz historical data), and mortgage rates peaked at 7.35% in November 2023. Today’s 5.19–5.89% range sits roughly in the middle of that decade-long swing. Borrowers choosing floating now are betting on continued OCR cuts large enough to close the 1%+ gap — a bet that requires rates to fall by more than the fixed-versus-floating premium before your loan term ends.

What are experts saying?

“We expect further OCR cuts to support economic recovery, bringing fixed rates under 5% by year-end.”

— Jarrod Kerr, Kiwibank Chief Economist (Kiwibank Research)

“Mortgage rates have fallen sharply since 2023 peaks, but affordability remains stretched.”

— Reserve Bank Governor, RBNZ Monetary Policy Statement (RBNZ MPS)

“Shop around — smallest rate differences can save thousands over loan term.”

— Canstar Analyst, Canstar NZ (Canstar NZ)

The pattern: Expert opinion splits between those focused on the rate direction (economists see continued falls) and those focused on affordability realities (the RBNZ acknowledges rates remain elevated relative to historical lows).

The stakes for NZ borrowers in 2026

The RBNZ’s 50-basis-point OCR cut on April 10, 2026, marks a turning point, but the relief is uneven. Borrowers with strong equity, stable income, and willingness to compare beyond the big four banks can access rates that weren’t available six months ago. Those locked into existing mortgages face break fees that may wipe out savings. Investors and Auckland-based borrowers carry structural premiums that won’t disappear even if the RBNZ cuts rates to 2021 levels.

For New Zealand homebuyers, the path forward is clear: use the comparison tools that update daily, verify rates against multiple sources, and run the numbers through a break-fee calculator before switching. The market is moving toward lower rates — but moving slowly, and the gap between the best available rate and the average borrower’s rate is wider than it needs to be. Interest.co.nz confirms borrowers who actively compare save an average of $4,200 per year by switching to a lower-rate product.

For first-home buyers facing DTI restrictions and rising property values, the calculus is harder: lower rates help monthly cash flow, but borrowing capacity caps mean you may qualify for less even as rates decline. For investors, the calculus is simpler: the 0.3–0.5% premium means fixed terms under 3 years don’t make sense unless you expect rapid appreciation to offset the carry cost.
