Hon CHRIS HIPKINS (Minister for COVID-19 Response): I was provided with advice by the Pullman incident review technical advisory group indicating that while it may not be possible to identify the precise transmission mechanisms involved in the recent transmission events at the Pullman, some of the likely key factors included the nature of the variant, the ventilation at the facility, and non-essential movement within the facility. I've asked for the health advice that I received to be released this week.
