To come back to the issue at hand, the cases that we are investigating at the moment, it is too soon to jump to conclusions about what has happened here, too soon to be drawing conclusions about where there may be weakness in the system. We do not know that it might have come from the laundry. That is a possibility. It's one of those things that's being investigated. A lot of people, a lot of experts, will say that's highly unlikely. But the reality is every potential scenario we're looking at with regard to these three cases falls into the highly unlikely category. So we can do everything we can to keep New Zealanders safe. We can try very hard to eliminate all risk. There is no such thing as eliminating every risk of COVID-19. It's a tricky virus. It finds a way and we have seen that repeatedly, but we have done very well in New Zealand. Our success is obvious, but it is not over and it won't be over for some time. We're gearing up to roll out vaccines. That's going to take some time. And as we roll out the vaccines, the risk will still be with us and we still need to be willing to respond when we need to.
