SIS director Rebecca Kitteridge has been recalled today to answer questions by MPs on the committee considering extensions to the powers of the domestic spy agency, especially ones about wanting 48 hours of warrantless surveillance in a emergency.
The Inspector-General of Intelligence and Security, Cheryl Gwyn, has also been asked to appear about oversight of such surveillance. The bill is ostensibly designed to deal with so-called foreign fighters for Islamic State but its measures would also have general application by the agency.
Today is a crucial day for the bill because key players in Labour and New Zealand First will decide what recommendations to put to their caucuses tomorrow morning.
National cannot rely on its support partners, United Future, Act and the Maori Party, all of which supported the bill to select committee but with opposition to the 48-hour clause.
Labour's foreign affairs spokesman, David Shearer, has hinted that his party's support could hinge on changing the 48 hours and having greater oversight. He thought if the SIS powers were extended Cheryl Gwyn should have greater oversight than proposed.
