The positive result came out after a round of Rapid Antigen Tests conducted on the team members on Saturday. Following the positive test, 21-year-old Kerr is in isolation at the team hotel.
A NZC media statement said that Kerr was the only player from the touring party to test positive, while “the rest of the group will continue to be monitored and tested, as required”.
But first, they will have another week of training at Millfield School in Somerset – including two practice matches against England A – before moving to Birmingham towards the end of July.
Kerr has been an integral part of the New Zealand set-up, having picked up 41 wickets in 41 bowling innings in T20Is at an economy of 5.94. With the bat, she has scored a total of 234 runs in 24 innings.
