Choosing a mortgage broker

The FMA suggests talking to more than one adviser and asking each of them:

what licence they have, or whose licence they work under
which lenders and products they can advise on
how they are paid, and whether you will pay any fees
how you can complain, and which dispute resolution scheme they belong to.

You can check a broker's licence on the Financial Service Providers Register. Ask for any fees in writing.
