Hon CHRIS HIPKINS: There's no question that the app was developed at speed during an emergency situation, and of course there is room for improvement. The next update of the app, which will be released before the end of this month, will deal with many of the common complaints from users, including that they can't manually enter in contacts where there isn't a QR code—that will be addressed—and that they can't retrospectively add information into the app; that will be addressed as well. But even if people aren't scanning QR codes, it's merely registering for the app that helps the Ministry of Health where contact tracing is required. Already, people's contact details from registering for the app have been used on multiple occasions as part of legitimate contact tracing exercises. So even signing up for the app and making sure that your contact details are up to date is actually a significant step that all New Zealanders should be taking.
