Hon Dr DAVID CLARK: I'm happy to come back to the member with a specific answer on that. I'm sure it has to do with the way in which clusters are categorised. My understanding, though—and I stand to be corrected on this—is that it's regarded as the St Margaret's Rest Home cluster because, indeed, that's where the residents were that were being cared for in the Waitakere Hospital, and that only a limited number of people beyond that have been infected. And I would expect that that's probably why it doesn't meet the definition of a cluster in the terms that the member is suggesting.
