Refinancing Your Auckland Investment Property in 2026: What Landlords Need to Know
What Does Refinancing Actually Mean?
Refinancing means replacing your existing mortgage with a new one, either with your current lender or a different one. The reasons landlords refinance include:
- Securing a lower interest rate
- Changing the loan structure (e.g., from P&I to interest-only, or splitting the loan)
- Extending or shortening the loan term
- Accessing equity for another purchase or renovation
- Consolidating lending across multiple properties
Refinancing does not change the amount you owe (unless you draw additional funds). It changes the terms under which you repay it.
Where Are Interest Rates in 2026?
As of May 2026, fixed mortgage rates from the major New Zealand banks are:
These rates are significantly lower than the 7-8% many landlords were paying in 2023-2024. The Reserve Bank’s OCR has dropped from 5.50% to around 3.25%, and forecasts suggest it may stabilise between 2.00% and 3.50% over the next two years.
If you are currently on a fixed rate above 6%, refinancing could deliver substantial monthly savings.
Current NZ Fixed Mortgage Rates (May 2026)
| Fixed Term | Lowest Available Rate | Offered By |
|---|---|---|
| 6 months | 4.49% | ANZ, ASB, BNZ, Kiwibank |
| 1 year | 4.65% | ASB, BNZ |
| 2 years | 5.19% | BNZ, Westpac |
| 3 years | 5.39% | BNZ |
| 5 years | 5.79% | BNZ, Westpac |
When Does Refinancing Make Sense?
Refinancing is worth considering when:
- Your fixed term is expiring, and current market rates are meaningfully lower
- You are on a floating rate that is not competitive, and your lender is not willing to match market rates
- You want a different loan structure (e.g., interest-only, split loan, or different term) that your current lender does not offer
- You have strong equity (at least 30-35% equity in the property), and other lenders are offering better deals
- You want to access equity to fund a renovation or a deposit for another property
What Are the Costs of Refinancing?
Refinancing is not free. Before switching lenders, factor in:
- Break fees: if you break a fixed-term mortgage early, you may owe a break fee. This can range from a few hundred dollars to tens of thousands, depending on your rate, balance, and how much time remains on your term.
- Discharge fees: some lenders charge a discharge fee when you leave (typically $200-$400).
- Valuation costs: the new lender may require a registered valuation, which costs $500-$1,000 for a standard residential property.
- Legal fees: your solicitor will handle the legal paperwork, typically costing $800-$1,500.
In many cases, the new lender will offer a cash contribution to cover some or all of these costs, particularly if your lending is substantial. Ask about this upfront.
Equity Requirements for Investment Property Lending
Investment property mortgages have stricter requirements than owner-occupied loans. Most lenders require:
- At least 30-35% equity in the investment property (i.e., a maximum LVR of 65-70%)
- Sufficient servicing through rental income and/or other earnings
- Clean credit history (some lenders are more conservative than others)
If your property has declined in value since you purchased it, your equity position may be lower than expected. This can limit your refinancing options, so it is worth getting a realistic valuation early in the process.
How to Structure Your Investment Property Loan
Refinancing is also an opportunity to restructure your lending for better performance. Common strategies include:
Splitting your loan across multiple fixed terms
Rather than fixing your entire loan at one rate, split it across short and longer terms. This gives you flexibility to take advantage of rate drops on the shorter portion while locking in certainty on the longer portion.
Using interest-only on the investment while paying down your home loan
Since investment property interest is 100% tax-deductible from 1 April 2025, some landlords keep their investment mortgage on interest-only while directing spare cash toward their personal home loan, where interest is not deductible. This strategy can reduce your overall tax bill while paying off non-deductible debt faster.
Fixing at the right term length
With rates potentially continuing to fall, shorter fixed terms (6 months to 1 year) allow you to refix sooner at lower rates. However, if you prefer certainty, a 2-3 year term locks in a known cost.
A mortgage adviser like Float Mortgages can help you model these options and find the structure that best suits your goals.
Tax Considerations When Refinancing
The key tax change for 2025-2026 is the full restoration of interest deductibility. From 1 April 2025, you can claim 100% of the interest on your investment property mortgage as a tax deduction.
This means:
- Your mortgage interest is fully deductible regardless of when you purchased the property
- Refinancing to a different lender does not affect your deductibility
- If you draw additional funds for property improvements, the interest on those funds is also deductible (provided the funds are used for the rental property)

The Refinancing Process: Step by Step
- Review your current position: calculate your current costs, equity position, and what you want to achieve
- Talk to a mortgage adviser: discuss your options with a broker who can compare offers across multiple lenders
- Compare the numbers: weigh break fees, legal costs, and cash contributions against the long-term savings
- Apply: complete the application with your chosen lender, providing income, expense, and property documentation
- Settlement: your solicitor handles the legal transfer between lenders
- New terms take effect: once settled, your new repayment structure begins
The process typically takes four to six weeks from application to settlement.

Frequently Asked Questions
You can, but your options may be limited. If your LVR has increased above 65-70%, some lenders will not approve the refinance. In this case, negotiating with your current lender for better terms may be a more practical option.
Trying to time the bottom of the rate cycle is risky. If your current rate is significantly above market and your fixed term is expiring, acting now delivers guaranteed savings. You can always refix at a lower rate later if rates continue to fall.
On a $600,000 loan, a 0.5% rate reduction saves approximately $3,000 per year. Whether it is worth refinancing depends on the costs involved (break fees, legal fees, valuation). If the costs are low or covered by the new lender, a 0.5% saving is almost always worthwhile.
Yes, provided the new lender approves interest-only for your situation. This is a common strategy for landlords looking to maximise cash-flow improvement in a single step.
