A testing blitz has been on in several Waikato towns today after three cases emerged from a household on the Hauraki Plains.
The three are household members of a prisoner on bail, who returned to Whakatiwai nearly two weeks ago.
Two of them go to Mangatangi School, near Miranda, and one may have been infectious while there on Thursday.
A steady flow of people have been through a hurriedly arranged testing centre today.
Andrew McRae has been at the Wharekawa Marae, on the western shore of the Firth of Thames.
