Hon CHRIS HIPKINS (Minister for COVID-19 Response): If the member's referring to the joint briefing by the Department of Prime Minister and Cabinet and the Ministry of Health that I requested and then subsequently proactively released on 10 December, then the answer to that first part of the question is yes. In answer to the second part of the question, the ongoing use of vaccination certificates continues to be a conversation with officials. We've yet to receive formal advice on when would be the right time to stop using vaccination certificates, but it continues to be something that we keep under active review.
