"Those people who have been illegally spied on by the GCSB at the very minimum deserve to know whether they have been the subject of surveillance," she told Radio New Zealand today.
"At the very least these people have been subject to criminal offending by the state, they've had their human rights violated and they deserve to be able to seek some sort of remedy for that," she said.
If the Privacy Commissioner could not help her get the information she was seeking, she would take court action against the GCSB and would consider representing the other 88 people who may have been illegally spied on by the agency, she told RNZ.
She noted internet mogul Kim Dotcom's case against the GCSB, saying it showed the courts are not willing to put up with this "nonsensical national security kind of caveat they're trying to invoke".
Ms Morse wanted those responsible for spying fired and the GCSB closed down.
"Potentially that's not a realistic remedy but we need to get a lot more life and air into the GCSB and the workings of that agency."
GCSB director Ian Fletcher told RNZ in a statement that to confirm who or what the agency might have been investigating or not would potentially identify law enforcement or national security priorities.
