The Government has not ruled out handing over more powers to the Security Intelligence Service for mining and using people's personal data.
A recently released report found faster and wider harvesting of data is a priority for bolstering counter-terrorism efforts.
The review was carried out in mid-2019 by an independent expert from a Five Eyes partner, and looked at how the SIS performed before the Mosque attacks.
It recommended the spy agency explore the government's appetite regarding data mining, but accepted there would be some reticence about it.
Minister for the Government's spy agencies, Andrew Little, spoke with Political Editor, Jane Patterson.
