This brings me to the issue of self-isolation that the Prime Minister announced just on Saturday night, and I must say quite clearly, from the point of view of the Opposition and so many New Zealanders, it is not clear to us quite how this would work. So we could have had 10,000 people getting off aeroplanes yesterday who had to self-isolate because they had just arrived in New Zealand, and where were they doing this? There are reports of them checking into hotels, and the hotel workers and the owners of the hotels are very uncertain about what that self-isolation means.
