How to Prepare for a Fixed-Rate Mortgage Expiry on Your Auckland Rental
What Happens When Your Fixed Rate Expires?
When your fixed term ends, your loan automatically rolls onto your bank’s floating (variable) rate unless you take action. Floating rates are typically 1-2% higher than the best fixed rates, so this default option is almost always more expensive.
You generally have three options at expiry:
- Refix at a new fixed rate (same bank, new term)
- Refinance with a different lender for a better deal
- Restructure by changing the loan structure (interest-only, term extension, split loan)
You can also combine these. For example, refinance to a new lender and switch to interest-only at the same time.
When Should You Start Preparing?
Start at least 60 to 90 days before your fixed term expires. This gives you time to:
- Review current market rates across multiple lenders
- Get advice from a mortgage broker
- Complete any paperwork if you decide to refinance
- Arrange a property valuation if required
Most banks will let you lock in a new fixed rate up to 30 days before your current term expires. Some brokers can negotiate pre-approval terms even earlier.
Understanding the Current Rate Environment
As of May 2026, one-year fixed rates are around 4.65%, two-year rates around 5.19%, and shorter 6-month terms at 4.49%. These are significantly lower than the 7%+ rates many landlords locked in during 2023-2024.
The OCR has fallen from 5.50% to approximately 3.25%, with economists forecasting further cuts or stabilisation between 2.00% and 3.50%. This creates an environment where shorter fixed terms may offer an advantage: you can refix sooner if rates continue to fall.
Short-Term vs Long-Term Fixed Rates: How to Choose
There is no single “right” choice. It depends on your risk tolerance, cash flow needs, and view on where rates are heading.
A common strategy is to split your loan across two terms. For example, fix half at 6 months and half at 2 years. This gives you some exposure to potential rate drops while locking in partial certainty.
Fixed Term Comparison (May 2026)
| Fixed Term | Typical Rate (May 2026) | Best For |
|---|---|---|
| 6 months | ~4.49% | Landlords who expect rates to fall further and want to refix soon |
| 1 year | ~4.65% | Good balance of low rate and flexibility |
| 2 years | ~5.19% | Landlords who want medium-term certainty |
| 3 years | ~5.39% | Those who value stability and are less concerned about short-term rate movements |
| 5 years | ~5.79% | Long-term certainty, but higher rate locks you in |
Should You Refix with Your Current Bank or Refinance?
At expiry, you are not obligated to stay with your current lender. Refinancing to a different bank can offer:
- Lower rates (different banks are competitive at different times)
- Cash contributions to cover switching costs
- Better loan structures (e.g., more flexible interest-only terms)
However, refinancing involves costs (legal fees, valuation, potential discharge fees) and takes four to six weeks. If the rate difference is small (less than 0.2-0.3%), staying with your current bank and negotiating may be simpler and equally effective.
A mortgage adviser like Float Mortgages can compare offers from multiple lenders and advise whether switching is worth the effort for your situation.
Should You Switch to Interest-Only at the Same Time?
A fixed-rate expiry is a natural time to review your entire loan structure. If cash flow is tight, switching to interest-only at the same time as refixing can deliver a significant reduction in monthly repayments.
On a $600,000 loan at 4.65%:
- P&I (30 years): approximately $3,100 per month
- Interest-only: approximately $2,325 per month
- Monthly savings: approximately $775
This is a meaningful difference for a property that is currently running at a loss. Remember, interest-only requires lender approval and typically requires at least 20% equity.
Tax Implications at Expiry
Your fixed-rate expiry does not change your tax position, but it is a good time to ensure you are set up correctly:
- From 1 April 2025, 100% of mortgage interest is tax-deductible for investment properties
- If you refinance, the interest on the new loan remains deductible (provided the funds are used for the rental property)
- If you draw additional equity for non-property purposes, the interest on those additional funds is not deductible

Frequently Asked Questions
Your loan will roll onto the bank’s floating rate, which is typically 1-2% higher than the best fixed rate. This increases your repayments immediately. Always refix or restructure before expiry.
You can break your fixed term early, but you will usually pay a break fee. Whether this is worthwhile depends on the difference between your current rate and the rate you could fix at, and how long remains on your term. Your broker can calculate the break-even point.
Not necessarily. Splitting your loan across two or three terms gives you diversification: some portions refix sooner (capturing potential rate drops), while others provide longer-term stability.
Next Steps
A fixed-rate expiry is a chance to reset your investment strategy. Do not let it pass by defaulting to whatever your bank offers. Take the time to review your options, talk to an adviser, and choose the structure that supports your goals for the next phase of your investment.
At the same time, make sure the property itself is performing well. A well-managed property with strong tenants and market-rate rent makes every lending decision easier.
