Rt Hon JACINDA ARDERN: Yes. These are conversations that I've actually had relayed to me around what's been available in the private sector. We have directly raised the possibility and the use of PCR testing using saliva directly with the likes of the Institute of Environmental Science and Research and with health officials, because we have the same interest in this that you do. The response that we get is the one that we're sharing in this House: that whilst they see it as being something that we should be utilising, there is just that level of caution of "Let's make sure we do it properly so that we don't lose some of the effective measures that we already have to keep us safe."
