What's defined as a good home loan may differ from person to person, but for a home loan in New Zealand you will want to split your mortgage into a minimum of two fixed loans and then have a small amount as a revolving credit. You should make sure that you can pay extra onto the fixed loans so that you can pay the loans off faster when you can, but without changing the underlying loan term as that can cause unwanted financial pressure when interest rates increase. The best home loans are provided by AIA Go Home Loans and TSB Bank who both offer fixed home loans that are very flexible and also are typically very competitive.
