Police Powers and Responsibilities Act 2000

A person is not excused from producing a document or making a document available when required to do so by a production order on the ground that—

producing or making the document available might tend to incriminate the person or make the person liable to a penalty; or

producing or making the document available would be in breach of an obligation, whether imposed by any law or otherwise, of the person not to disclose the existence or contents of the document.

Subsection (3) applies if a person produces a document or makes a document available under a production order.

The following are not admissible against the person in any criminal proceeding, other than a proceeding for an offence against section 194 in relation to producing the document or making the document available—

the fact that the person produced the document;

the fact that the person made the document available;

any information, document or thing directly or indirectly obtained because the document was produced or made available.
