The new interim spy agency watchdog wants transparency to be a key focus.
Madeleine Laracy is the acting Inspector-General, overseeing the Government Communications Security Bureau (GCSB) and the New Zealand Security Intelligence Service (SIS).
She told Newshub Nation on Saturday the agencies should not always be in the shadows.
"Transparency is at the heart of accountability to the public," she told host Simon Shepherd.
"It's been recognised by Governments around the world that it's as much as possible as can be said about the activities of intelligence and security agencies, it's generally a good thing to put that information in the public domain.
"There are many operational details that are classified - sensitive to national security - and that material can't be in there. But the way the agencies go about their work, the rules that govern them, what those rules mean in the particular context - all of that material is enormously important for the public to understand how the agencies work and to have confidence in them."

- GCSB links 'malicious cyber activity' to Russian government
- GCSB, NZSIS concerned about foreign interference
Both agencies are under review for their roles prior to the Christchurch mosque shootings. Laracy declined to talk about the details while they are under review.
