The objectives of this audit were to:

• provide assurance to the Parliament on the effectiveness of internal audit operations; and
• determine whether internal audit generally operates at, or near, recognised better practice.

The criteria used to measure internal audit effectiveness were based on four principles developed as part of the audit. These principles and criteria deal with the level of management support and authority; the use of a risk-focus to address client needs; the appropriate balance of skills and knowledge; and the use made of continuous improvement processes and measurement of performance effectiveness.
