Your Guide Through the Lending Market

A mortgage broker — officially called a mortgage adviser in NZ — gives financial advice about home loans and other lending products. They work with you to understand your budget and goals, work out what you can realistically afford to borrow, compare options across lenders, explain how each loan works, and manage the process through to settlement.

Unlike going to a single bank, a broker can compare rates and lending criteria across multiple lenders at once, which matters because different banks assess the same borrower differently.

Comparing Lenders

Shopping your application across multiple banks rather than just one.

Application Management

Preparing and submitting documentation, then managing it through to approval.

Settlement Coordination

Working with your lawyer and bank to keep everything on track through to settlement.

A mortgage adviser's service is normally free to you — they're paid by the lender, not the borrower.

Who Benefits Most From Using a Broker

A broker isn't mandatory, but tends to help most in these situations.

First home buyers

Navigating pre-approval, KiwiSaver withdrawal, and grants can be simpler with expert help.

Self-employed borrowers

More complex income documentation benefits from a broker who knows what each lender wants.

Anyone comparing multiple lenders

Saves the time of approaching several banks individually.

Quick Summary
