Hon CHRIS HIPKINS: I don't necessarily agree with the assertion in the member's question. There have been regular ongoing audits of all of our facilities. Each one of those audits identifies new areas where there can be improvement. Usually, it's just relatively minor improvements that need to be made. In this particular case, though, there are some extra precautionary measures that can be taken. But it's important to note, as I did in my primary answer, that there was no conclusive finding here. There was no absolute certainty about exactly what had happened, so these are extra precautionary steps that can be taken.
