Hon CHRIS HIPKINS: As I indicated, it's not currently accredited to be used for the purposes of diagnostics; it's only accredited for the use of surveillance. We are using it in that capacity at the moment. We are rolling it out more broadly, but there are still some additional hurdles to go through, including validation of the test results, to give us confidence that we're not going to miss cases or give people false confidence if they get a negative result when perhaps they shouldn't.
