Uniform Civil Procedure Rules 1999

Subject to an order of the court, the court may give leave to deliver interrogatories—

on application without notice to another person; and

only if the court is satisfied there is not likely to be available to the applicant at the trial another reasonably simple and inexpensive way of proving the matter sought to be elicited by interrogatory.

The application must be accompanied by a draft of the interrogatories intended to be delivered, unless the court otherwise directs.

However, a Magistrates Court may not give leave for this subdivision unless the amount sued for is more than $7,500.
