David Seymour: Point of order, Mr Speaker. On the previous supplementary, I waited for the second one from the Leader of the Opposition, but I was very interested in the question of will the police powers allow police to stop people walking around in their destination. Now, the Prime Minister said that she thought it would be more prudent or efficient to use them at the point of departure, but that is a very important question—what will these police powers allow—and I don't believe that was addressed.
