There comes a point for some borrowers where the question stops being “How do we catch up?”
and becomes:
“Can we realistically refinance this before things get worse?”
This article is for borrowers who are already behind on mortgage repayments, dealing with arrears, or worried the current loan may no longer be sustainable — and want to understand whether refinancing may still be possible in New Zealand.
The short answer is: sometimes yes.
But refinancing while already behind on repayments is usually assessed very differently from a standard home loan application.
Refinancing While Behind Is Usually More Complex
When repayments are already overdue, lenders generally look much more closely at:
The further the arrears position has progressed, the more carefully the application is usually assessed.
This is because the lender is no longer only assessing “Can this borrower afford a mortgage?”
but also:
“Can this position realistically stabilise from here?”

One important distinction is that refinancing the mortgage is different from temporarily restructuring repayments with the current lender.
Some borrowers first explore:
That is because refinancing usually requires:
If you are still earlier in the repayment-pressure stage, our article on mortgage repayment relief options in NZ may be more relevant first.
Refinancing may not be the first step if the arrears position is still changing, income is unstable, or the current lender has not yet assessed whether short-term support could help stabilise the account.
In those situations, the priority may be to understand the arrears position clearly before assuming a new lender will be the right solution.

Every lender looks at risk differently.
But when arrears already exist, lenders commonly assess:
Some lenders may also consider:
For borrowers already dealing with growing arrears, our article on how mortgage arrears can escalate in NZ explains how these situations commonly progress over time.
When someone is already behind on repayments, the refinance question usually needs to be looked at carefully. At Platinum Mortgages, the focus is not just whether another lender might consider the application, but whether the arrears position, future repayments, and wider household budget can realistically work together from here.
That distinction matters because refinancing may still be possible in some situations, but it should be assessed as part of the whole financial position — not treated as a quick reset.
In some situations, specialist or non-bank lending may come up during a refinance assessment if mainstream bank criteria are difficult to meet.
But this still needs to be assessed carefully, because a different lender does not remove the need for affordability, a workable repayment plan, and a realistic path forward.
Specialist lending options may involve:
That is why refinancing while behind on repayments should not be viewed as an automatic solution. The underlying financial position still matters enormously.

One of the most common misunderstandings is assuming refinancing automatically fixes mortgage stress.
Sometimes refinancing can improve the position significantly.
But if:
Then, changing lenders alone may not fully resolve the broader issue.
That is why lenders usually assess not only the current arrears position, but whether the overall mortgage structure realistically fits the borrower’s financial situation going forward.
The earlier borrowers understand where the position realistically stands, the more flexibility there may still be.
For some people:
For others, the arrears may already have progressed far enough that fewer realistic options remain available.
This is why the question is not only whether refinancing is possible, but whether it is the right step for the position the borrower is actually in.
What matters most is understanding the position clearly before the repayment gap becomes significantly harder to recover.
Refinancing while already behind on repayments is rarely a simple reset.
Lenders usually want to understand not only whether the arrears can be cleared, but whether the overall financial position now looks realistically sustainable going forward.
