Then there's education. I just presented awards to the International Baccalaureate scholars this weekend. What an extraordinary group of children who managed to make it through with stoicism even though they were studying right up to the last moment without knowing if their examinations would go ahead. These are the costs that New Zealanders face when there is a lockdown. But actually, the facts are it is necessary to have one if the rest of the Government's defences are as weak as what we have at the moment.
