Fixed vs Floating Mortgage Rates NZ: Which Should You Choose in 2026?

Introduction: The Most Important Decision After Getting a Mortgage

Once you have been approved for a home loan in New Zealand, the next big question is whether to lock in a fixed rate, go with a floating rate, or use a combination of both. This single decision can save — or cost — you thousands of dollars over the life of your mortgage.

In April 2026, with the Reserve Bank's Official Cash Rate (OCR) sitting at 2.25% after nine consecutive cuts since August 2024, the rate environment has shifted dramatically. Fixed rates have fallen to multi-year lows, and borrowers face a genuine dilemma: lock in now, or stay flexible in case rates move even further?

This guide breaks down everything you need to know about fixed versus floating mortgage rates in New Zealand, with up-to-date rate data and practical strategies to help you make the right choice for your situation.

What Are Fixed Mortgage Rates?

A fixed rate mortgage locks your interest rate for an agreed period — typically six months to five years in New Zealand. During this fixed term, your repayments stay exactly the same, regardless of what happens in the broader economy or with the OCR.

When your fixed term expires, you can choose to re-fix for another term, switch to a floating rate, or negotiate a new deal with your lender — or a different lender entirely.

Current Fixed Rates in New Zealand (April 2026)

Fixed rates across the major banks have fallen significantly since mid-2024. Here is a snapshot of where the big five sit right now:

Rates shown are standard specials for owner-occupiers with at least 20% equity. Rates change frequently — compare the latest rates on RatePal for the most current figures.

As you can see, the sweet spot in the current market is the six-month to one-year fixed term, where rates are lowest. Longer terms carry a premium because lenders are pricing in the possibility that rates could rise again over the coming years.

What Are Floating Mortgage Rates?

A floating rate (also called a variable rate) moves up and down over time. In New Zealand, floating mortgage rates are heavily influenced by the Reserve Bank's Official Cash Rate (OCR) — the benchmark interest rate that the RBNZ uses to manage inflation and economic growth.

When the RBNZ cuts the OCR, banks typically reduce their floating rates (though not always by the full amount). When the OCR rises, floating rates go up too. As of April 2026, floating rates from the major banks sit in the range of roughly 5.75% to 5.99% — Kiwibank is cheapest among the big five at 5.75%, while ANZ and ASB sit at 5.79%. The Co-operative Bank's 4.99% is the market-leading floating rate, more than 75 basis points below the big five. Even at these lower levels, floating still sits above the best short-term fixed rates, though the gap has narrowed considerably from the 2024–2025 cycle peak.

The gap between floating and fixed rates is not unusual. Floating rates include a flexibility premium — you are paying more in exchange for the freedom to make unlimited extra repayments, repay the loan in full, or switch lenders at any time without facing break fees.

How the OCR Affects Your Floating Rate

The OCR is the single most important driver of floating mortgage rates. Since August 2024, the RBNZ has cut the OCR from a cycle peak of 5.50% down to 2.25% — a dramatic easing cycle designed to stimulate the economy amid softening inflation. The cutting cycle paused in February 2026, and the April 2026 review confirmed the hold. Market pricing now suggests the first potential hike may not come until September 2026 at the earliest.

This matters because floating rate borrowers have already seen their repayments decrease substantially as banks passed through OCR cuts. However, with the cutting cycle now paused, the days of falling floating rates may be behind us for the time being.

Fixed vs Floating: Pros and Cons Compared

Here is a side-by-side comparison to help you weigh up the two options:

When Should You Choose a Fixed Rate?

Fixing your mortgage rate makes sense in several scenarios. The core advantage is certainty — you know exactly what your repayments will be for the next one to five years, which makes household budgeting far simpler.

Fix if you want stability and predictability

If your household income is relatively fixed (salary or wages) and you need to know exactly what goes out the door each fortnight or month, a fixed rate removes the guesswork. This is especially valuable for first home buyers who are adjusting to the costs of homeownership for the first time.

Fix if you think rates have bottomed out

With the OCR at 2.25% and most economists forecasting it to hold steady or edge upward, there is a reasonable argument that fixed rates are close to their cyclical low. Locking in a one- or two-year term at current rates could protect you from any future increases. That said, nobody can predict rate movements with certainty — if inflation stays subdued, rates could stay low for longer.

Fix if you are not planning to sell or refinance soon

Break fees on fixed mortgages can be substantial — sometimes tens of thousands of dollars if rates have moved significantly since you locked in. If you know you will stay in the property and keep the same loan for the full term, fixing carries less risk.

When Should You Choose a Floating Rate?

Floating rates are higher right now, but they offer something fixed rates cannot: complete flexibility. Here is when floating makes more sense.

Float if you want to make large extra repayments

If you have variable income (bonuses, commissions, freelance work) or expect a lump sum (inheritance, property sale, KiwiSaver withdrawal), a floating rate lets you throw that money straight at the mortgage with no restrictions or penalties. On a $500,000 mortgage, even $10,000 in extra annual repayments can shave years off your loan term and save tens of thousands in interest.

Float if you expect further OCR cuts

If you believe the RBNZ may need to cut rates further — perhaps due to a global economic slowdown or local recession — staying on floating means your repayments will decrease automatically as the OCR falls. In the current environment (April 2026), this is a less compelling argument than it was a year ago, since the cutting cycle appears to have paused.

Float if you might sell or refinance soon

Planning to sell your property within the next year or two? Floating avoids the risk of break fees entirely. Similarly, if you are looking to switch lenders to get a better deal, being on floating makes the transition seamless.

The Split Mortgage Strategy: Best of Both Worlds

You do not have to choose one or the other. Many smart New Zealand borrowers use a split mortgage strategy — dividing their loan across multiple tranches with different rate types and terms.

For example, on a $600,000 mortgage you might structure it as:

• $300,000 fixed for 1 year at 4.59% — for rate certainty on the bulk of the loan
• $150,000 fixed for 2 years at 4.89% — to diversify your re-fixing dates
• $150,000 floating at ~5.79% (big five) or 4.99% (Co-operative Bank) — for flexibility to make extra repayments

This approach is sometimes called a mortgage ladder. The fixed portions give you budgeting certainty and lower rates, while the floating portion lets you channel any extra cash directly into the loan. When each fixed tranche rolls off, you reassess the market and decide whether to re-fix, extend, or float.

Current NZ Market Analysis: What Is Happening with Rates in 2026?

The New Zealand mortgage market in early 2026 looks very different from a year ago. Here is a summary of the key dynamics:

The OCR has stabilised at 2.25%

After nine cuts between August 2024 and late 2025, the RBNZ paused its easing cycle and has held the OCR at 2.25% since February 2026. The April 2026 review confirmed the hold, citing geopolitical disruptions affecting oil and gas supplies, which are raising near-term inflation risks. Inflation remains at the upper end of the RBNZ's 1–3% target band. The next OCR review is scheduled for 27 May 2026, with most major bank economists expecting another hold and the first potential hike not pencilled in until September 2026 at the earliest.

Short-term fixed rates are at cyclical lows

One-year fixed rates of around 4.59% across all five major banks represent the lowest level since early 2022. The yield curve is upward-sloping — longer terms cost more — which suggests the market expects rates to rise over the medium term. This is why two-year rates (4.89%–5.19%) and three-year rates (5.29%–5.39%) carry a noticeable premium.

Bank competition is intense

With the housing market recovering and refinancing activity picking up, banks are competing aggressively on short-term fixed rates. This is good news for borrowers — it means there is room to negotiate, especially if you have strong equity (20%+ deposit) and a solid income.

What this means for your decision

In the current environment, fixing for a short term (six months to one year) offers an attractive rate and the ability to reassess relatively soon. Fixing for two or three years gives more certainty but at a higher cost. Floating is best reserved for the portion of your loan where you value flexibility above all else. Compare all current rates side by side on RatePal to see exactly where each lender sits today.

Frequently Asked Questions

Can I switch from fixed to floating before my term ends?

Technically yes, but you will likely face a break fee. The size of the fee depends on how much time is left on your term and how rates have moved since you fixed. In some cases it can be thousands of dollars. If you think you might need to break early, consider fixing for a shorter term or keeping a portion of your loan on floating.

What happens when my fixed rate expires?

When your fixed term ends, most banks will roll you onto their floating rate unless you actively choose a new fixed term. This is called "rolling off." Since floating rates are significantly higher than fixed rates, it pays to be proactive. Set a calendar reminder a few weeks before your term expires and check the latest rates to decide your next move.

Is it better to fix for one year or two years right now?

As of April 2026, one-year rates (around 4.59%) are noticeably cheaper than two-year rates (4.89%–5.19%). Fixing for one year gives you a lower rate and the flexibility to reassess sooner. However, if you strongly prefer stability and worry that rates could jump significantly in 12 months, a two-year fix provides a longer runway of certainty. Use the mortgage calculator to compare the total interest cost of each scenario.

Should I fix my entire mortgage or keep some floating?

Keeping a portion on floating is a smart strategy if you want to make extra repayments. A common approach is to fix 70–80% of the loan for rate certainty and keep 20–30% floating for flexibility. The Mortgage Optimizer tool can help you find the right split for your situation.

How often does the RBNZ change the OCR?

The RBNZ reviews the OCR seven times per year at scheduled Monetary Policy announcements. The next review dates are published on the RBNZ website. Changes to the OCR typically flow through to floating mortgage rates within days, and influence fixed rates over the following weeks.
