Hon CHRIS HIPKINS: No, in answer to the first part of the question. As with our alert level system—the one that we have just transitioned away from—there is a need to consider a balance of factors. We did not have hard and fast rules as to exactly the trigger points for moving between level 1 and level 2, level 2 and level 3, and level 3 and level 4. We made those decisions based on a balance of facts presented at the time.
