What are BNZ mortgage rates?

Current BNZ fixed rates for 6-month to 5-year terms

BNZ’s standard fixed rates as of late June 2026, updated on the bank’s official site, are:

• 6-month: 4.69% p.a. (BNZ official home loan rates page)
• 1-year: 4.79% p.a. (1News)
• 18-month: 5.09% p.a. (1News)
• 2-year: 5.29% p.a. (Interest.co.nz (personal finance data))
• 3-year: 5.29% p.a. (Opes Partners (property investment advisory))
• 4-year: 5.39% p.a. (Opes Partners)
• 5-year: 5.49% p.a. (Opes Partners)

BNZ floating rate and LVR premiums

BNZ’s floating rate is 6.09% p.a. and its revolving credit rate is 6.14% p.a., according to Squirrel (mortgage advisory platform). Loan-to-value ratio (LVR) premiums apply when the deposit is under 20%, meaning borrowers with less equity pay a higher effective rate. BNZ’s policy on LVR pricing is detailed on its official site.

How to read BNZ rate tables

BNZ publishes “carded” rates that are the standard advertised rates. These are per annum and apply to owner-occupiers. Special rates or cashback offers may be available for new customers or those with higher deposits. The rates shown on comparison sites like Squirrel and RatePal (mortgage comparison site) typically match BNZ’s advertised rates but may include special deal rates.

The implication: BNZ’s headline rates are only the starting point – actual costs depend on your deposit size.

What is the best mortgage rate in NZ right now?

Comparison of BNZ vs ANZ, ASB, Kiwibank, Westpac rates

Five major banks, one clear pattern: BNZ leads on longer-term rates but trails on the shortest terms.

Data sourced from Interest.co.nz and Opes Partners as of late June 2026.

The implication: BNZ is not the cheapest on short terms, but on 3- to 5-year fixes it ties with Westpac for the lowest rates. For a borrower wanting rate certainty over a longer horizon, BNZ is competitive.

Best rate for different loan terms

• 1-year: ASB at 4.59% (Opes Partners)
• 2-year: ASB and Westpac at 5.19% (Interest.co.nz)
• 3-year: BNZ and Westpac at 5.29% (Opes Partners)
• 5-year: BNZ and Westpac at 5.49% (Opes Partners)

Honeymoon rates and special offers

At the time of writing, none of the major banks are offering introductory or honeymoon rates. Cashback offers are available but vary by bank and loan amount. BNZ’s standard rates are the base pricing; any special deals typically require a deposit of 20% or more.

The pattern: shorter terms carry lower rates now, but locking in longer avoids refinancing risk if the OCR surprises upward.

Will mortgage rates go down in NZ in 2026?

Economist forecasts for 2026-2027

Trade Me economists have predicted a gradual decline in mortgage rates through 2026, though the exact timing remains uncertain. The RBNZ (New Zealand’s central bank) held the OCR at 3.50% in Q2 2026, citing inflation concerns. Some market analysts expect a 0.25% cut in late 2026 if economic conditions soften, as reported by 1News.

Impact of OCR decisions on mortgage rates

Mortgage rates closely follow the OCR. When the OCR rises, banks pass on the cost; when it falls, rates tend to drop. The current gap between wholesale swap rates and retail mortgage rates suggests that banks have room to cut if the OCR moves lower. However, the RBNZ has signalled caution, and no cuts are guaranteed in 2026.

Historical rate cycles and probability of drops

Historical data from the RBNZ (monetary policy data) shows that mortgage rates rarely drop below 4% unless the OCR falls below 2%. With the OCR at 3.50%, rates returning to 3% in 2026 is highly unlikely. A more realistic scenario is a gradual decline to around 4.5% on 1-year terms by 2027, according to some forecasts.

The catch: the RBNZ’s caution on inflation means any relief will be gradual, not dramatic.

Should I fix my mortgage for 1 or 2 years in NZ?

Pros and cons of 1-year fixed vs 2-year fixed

Current rate differential and break costs

The difference between BNZ’s 1-year and 2-year fixed rates is 0.50% (4.79% vs 5.29%). Over a $500,000 loan, that’s an extra $2,500 per year in interest for the 2-year fix. Break fees apply if you refix before the term ends; they are calculated based on the wholesale rate movement and can be significant.

Advice for first-home buyers and refinancers

• First-home buyers: If you need budget certainty, the 2-year fix provides stability. But be prepared for possibly higher payments if rates drop and you miss out.
• Refinancers: If you can handle some risk, the 1-year fix gives you a chance to catch lower rates in 2026. Consider splitting the loan – half on 1-year, half on 2-year.

The implication: the 0.50% premium for a 2-year fix is a hedge against rising rates – worth it if stability matters more than the lowest possible cost.

Can a 70 year old woman get a 30 year mortgage?

Age restrictions for NZ home loans

Most New Zealand banks, including BNZ, do not have a hard age cap but require a repayment plan that ensures the loan will be repaid by age 85–90. For a 70-year-old, a 30-year term would extend beyond that age and is unlikely to be approved without a substantial deposit or a younger co-borrower.

BNZ policy on older borrowers

BNZ assesses each borrower individually. According to its official home loan page, age alone is not a sole barrier, but lending decisions consider income, assets, and the ability to repay. A 70-year-old may be approved for a shorter term, such as 15 years, or may need to demonstrate a clear exit strategy (e.g., selling the property).

Alternatives: shorter terms, reverse mortgages

• Shorter loan term: A 15-year term would have higher monthly payments but may be feasible if the borrower has sufficient retirement income.
• Reverse mortgage: Available for seniors over 60, allowing them to access equity without monthly repayments. Providers include Heartland Bank and others.
• Interest-only mortgage: Some lenders offer interest-only periods for older borrowers, reducing monthly payments.

The pattern: a 30-year term at age 70 is unlikely, but BNZ and other lenders have workable alternatives for older borrowers.

Timeline: Key events affecting BNZ mortgage rates

• June 24, 2026: BNZ raises 6-month rate to 4.69%, 1-year to 4.79%, 18-month to 5.09%, 2-year to 5.29%; cuts 3-year to 5.29%, 4-year to 5.39%, 5-year to 5.49% (1News).
• Q2 2026: RBNZ holds OCR at 3.50% (RBNZ monetary policy statement).
• Late 2026 (forecast): Potential 0.25% OCR cut if economic conditions soften.
• 2027 (forecast): Mortgage rates expected to decline further, possibly reaching 4.5% on 1-year terms.

The pattern: BNZ’s June 24 move created a steeper yield curve – short rates up, long rates down – signalling uncertainty about the pace of future OCR cuts.

Clarity: What’s confirmed and what’s unclear

Confirmed facts

• BNZ’s current rates as published on its official site and reported by 1News and Interest.co.nz.
• RBNZ OCR at 3.50% in June 2026 (RBNZ).
• BNZ LVR premiums apply above 80% LVR (BNZ policy).

What’s unclear

• Exact timing of future OCR cuts.
• Whether mortgage rates will fall below 4% in 2027.
• BNZ’s future rate adjustments – further hikes or cuts depend on market conditions.

The implication: the known facts support a cautious outlook – rates are elevated but trending down, with no guarantee of speed.

Expert perspectives

The rate changes are part of our regular review of home loan rates to remain competitive in a dynamic market.

— BNZ spokesperson, as reported by Interest.co.nz (personal finance data)

We expect mortgage rates to ease gradually through 2026 as inflation pressures moderate, but borrowers should not count on a rapid drop.

— Trade Me economist, as cited in 1News (New Zealand news outlet)

The OCR decision reflects the need to balance inflation control with economic growth. We are watching data closely.

— RBNZ Governor, statement from RBNZ monetary policy statement (official site)

The pattern: BNZ, economists, and the central bank all point to gradual easing – no one is predicting a sharp drop.

For New Zealand borrowers, the choice between fixing for 1 year or 2 years hinges on risk tolerance. The 1-year fix offers a lower rate now and a chance to benefit if rates fall, but comes with renewal uncertainty. The 2-year fix provides stability at a higher cost. For a first-home buyer with a tight budget, the 2-year fix may be worth the extra $2,500 per year to avoid payment shock. For a homeowner with equity, splitting the loan between 1-year and 2-year terms could be the smartest path.
