Hon CHRIS HIPKINS (Minister for COVID-19 Response): Discussion on how to ensure that any internal borders are as safe as possible have been ongoing since the current outbreak began, and that involved discussion around testing. I first received formal advice from the director-general regarding surveillance testing for essential workers crossing the proposed level 4-2 boundary on Saturday evening, 4 September. Cabinet then agreed on Monday that essential workers would be required to be tested within the last seven days before crossing an alert level boundary into and out of an alert level 4 area. In regard to the second part of the member's question, yes. This is the first occasion we've required a level 4 - level 2 boundary split, and the work completed over the last five days has shown that the system remains robust and adaptable due to the changing nature of the virus. The Government has and continues to work closely with the sector on the implementation of this process. My ministerial colleagues have been in regular discussion with the heads of the sector. I'd like to acknowledge the efforts of everyone involved in this piece of work, including the sector, who have been particularly responsive in creating workable solutions to these challenges. Like all aspects of our response to COVID-19, we continue to look at our processes and we continue to adjust as necessary.
