The Privacy Commissioner has given approval to changes made to the Search and Surveillance Bill.
The legislation aims to update old laws, but has attracted criticism that it goes too far in the powers it extends to Government agencies, including the police.
Parts of the bill have been rewritten, and the Justice and Electoral committee is hearing submissions on the changes today.
Commissioner Marie Schroff told MPs that, at first, her office had a number of concerns.
But she says overall, her office is satisfied with the changes made to address the points that were raised.
