Partner, who has been isolated since his return. Has gone positive. 6 days after returning home. Meaning he WAS infectious toward the end of the trip and passed it to her. Don't count chickens yet. Hence the delays in decisions and extensions right now.
He tested negative, great. Now he's positive. How many concerned Kiwi's got promptly tested and phew, I'm clear?
She was vaccinated as well (only with a single jab like him) though, so delayed onset of symptoms or testing positive is something that has been reported. We know that Delta typically has a quicker onset period of symptoms for people who have become infected.
