A new lender has approved my mortgage switch. What needs to happen before the old loan is paid off and the new one starts?
In New Zealand, once your new lender has approved your mortgage switch, the next stage is usually handled by your solicitor or conveyancer, working with both lenders. Approval is not the same as settlement: the old mortgage generally remains in place until the new loan funds and the existing loan is repaid.
What needs to happen before the switch is complete?
- The new lender completes its final checks
Your lender may need to confirm any outstanding conditions, such as income or employment details, property valuation, insurance, and the required loan documents. You may need to sign the new loan agreement and mortgage documents.
- Your solicitor arranges the legal paperwork
Your solicitor reviews the new mortgage documents and arranges the legal steps to register the new lender's mortgage against your property. If you're switching lenders without selling your home, this is generally a refinance rather than a property sale.
- The old lender provides a final payout figure
Your solicitor obtains the amount needed to repay the old loan on the settlement date. This can include outstanding principal, accrued interest, discharge or administration fees, and any early repayment or break fee if applicable.
- A settlement date is agreed
Your solicitor coordinates with both lenders to ensure the new loan funds are available when the old loan is due to be repaid. Any cash contribution, cashback conditions, or funds you need to provide are also confirmed.
- Settlement takes place
The new lender advances the funds, usually through your solicitor. The old mortgage is paid off, and the legal registration of the new mortgage and discharge of the old mortgage are handled as part of the transaction.
- Your new repayments begin
The new loan follows its agreed repayment schedule. Check the first payment date, repayment amount, interest rate and loan structure, and confirm that any old direct debit or automatic payment is cancelled only when appropriate.
What you should check now
Before settlement, I’d confirm these five things with your solicitor or mortgage adviser:
- All approval conditions are satisfied and the new lender is ready to release the funds.
- The payout figure is confirmed, including any fixed-rate break fee or other exit costs. Mortgages and home loansMove your home loan to ASB
- You know the settlement date and when the old loan will be repaid.
- You understand the new repayment arrangements, including the first payment date and whether repayments will be weekly, fortnightly or monthly.
- Any cashback or switching costs are clear, including whether you need to repay a previous cashback incentive or pay legal fees. Mortgage adviceSwitch your home loan
You can also read your new lender's refinancing guide from BNZ for an example of how the process works in New Zealand.
One important point: don't independently cancel your old mortgage repayments before settlement is confirmed. Keep the existing payments going as required until the old lender confirms the loan has been repaid and your solicitor confirms settlement has completed.
How long does it take?
It depends on whether the lender has finished its checks, the paperwork is signed, and the solicitors have everything they need. Your approval may be in place well before the actual settlement date.
Have you already signed the new loan documents, or have you only received conditional/unconditional approval so far? That will help me explain what stage you're likely at and what still needs to happen.
