In New Zealand, Harmoney works with Equifax (formerly known as Veda) and Centrix. These are credit reporting agencies, also known as credit reporters or credit burueaux. They gather and share information about your past financial behaviour with credit providers. This helps credit providers to make future decisions. 

In Australia, the credit reporters Harmoney works with are Dun & Bradstreet and Equifax.

This past financial behaviour (both positive and negative information) is contained in what is called a credit report. 

Given the importance of the information in credit reports, the Privacy Commissioner in NZ has imposed special controls to ensure credit reporters act fairly and that information in the system is reliable and used only for permitted purposes. In Australia the same task is undertaken by the Office of the Australian Information Commissioner.

However, it's also important that you regularly check your own credit report and, if necessary, ask credit reporters to correct any errors on it.
