What is the difference between codifying and consolidating statute?

A consolidating statute repeals and re-enacts existing statutes relating to a particular subject. Its purpose is to state their combined effect and so simplify the presentation of the law. It does not aim to alter the law unless it is stated in its long title to be a consolidation with amendments. An example of a consolidating statute is the Trade Union and Labour Relations (Consolidation) Act 1992.
