Are any matters addressed by the new legislation covered by existing legislation?

New legislation should not restate matters already addressed in existing legislation.

Where a provision in existing legislation satisfactorily addresses an issue, it is preferable not to repeat that provision in new legislation. This kind of duplication often results in unintended differences, especially where legislation is amended over time or where the legislation is intended to address a different policy objective.

In some cases, existing legislation can be used to supplement new legislation. Some Acts are of general application (the Interpretation Act 1999). Others must be expressly applied by the new legislation (see the Ombudsmen Act 1975).

Where appropriate, flag provisions may be used in the new legislation to identify (but not restate) the relevant provisions of the other legislation (see, for example, section 8 of the Local Government (Auckland Council) Act 2009 or section 30B(3) of the Receiverships Act 1993).
