Legal Practitioners Act 1981

It is not an excuse for a person to refuse or fail to answer a question or to produce a document as required under this Act on the ground that to do so might tend to incriminate the person, or make the person liable to a penalty, or on the ground of legal professional privilege.

If a person objects to answering a question or to producing a document on the ground that the answer or document might tend to incriminate the person or make the person liable to a penalty, then—

in the case of a person who is required to produce a document—the fact of production of the document (as distinct from the contents of the document); or

in any other case—the information furnished in compliance with the requirement, is not admissible in evidence against the person in proceedings (other than proceedings in respect of the making of a false or misleading statement or perjury) in which the person might be found guilty of an offence or liable to a penalty.

If a person objects to answering a question or to producing a document on the ground of legal professional privilege, the answer or document will not be admissible in civil or criminal proceedings against the person who would, but for this section, have the benefit of the legal professional privilege.
