Hon CHRIS HIPKINS: I think, as I mentioned earlier in question time, we began our roll-out of saliva testing in January. That roll-out was paused whilst the people involved in it were diverted to focus on the case investigations around the Northland case that we dealt with. We do have a limited workforce and we need to prioritise them to working on the issues that are the most pressing, and the most pressing was investigating those cases to make sure there was no further spread of the virus.
