Refinance Legal Fees in NZ: What You're Paying a Lawyer For

Why a refinance needs a lawyer at all

A mortgage is a registered interest on your property's title. Removing one lender's mortgage and registering another's can only be done through Land Information New Zealand's system by a lawyer or licensed conveyancer. Your new lender won't release any money until that person has given a solicitor's certificate confirming the paperwork is in order.

So although a refinance feels like an admin exercise, there's real legal work in it.

What the lawyer actually does

1. Receives loan instructions from the new lender and checks them against your approval.
2. Explains the loan agreement and mortgage to you and witnesses your signatures. Many firms now do this by video call.
3. Verifies your identity, as anti-money-laundering law requires.
4. Asks your current lender for a repayment figure for settlement day.
5. On settlement day, receives the new loan, repays the old one, then registers the discharge and the new mortgage.
6. Reports back to you and the lender once registration is complete.

What it costs

Most firms charge a fixed fee for a standard residential refinance. As at November 2026, the published fees we see are mostly between about $900 and $1,800 plus GST and disbursements. Disbursements are the firm's own costs passed on to you, such as title searches, registration fees and identity checks.

Expect to pay more if the property is owned by a trust or company, if more than one property is security for the loan, or if guarantees are involved, because each adds documents and advice. Get the quote in writing and ask whether it includes GST and disbursements. That's where quotes that look cheap catch up.

Who really pays

Often the new lender does, in effect. Many lenders offer a cash contribution when you move your lending to them, and it frequently exceeds the legal bill. A few pay a set amount specifically towards legal costs. Both come with a condition that you stay for a set period, so read how cashback offers work before you count the money.
