Murupara cases
There are now two Covid-19 community cases in Murupara, a town that has one of the Bay of Plenty's lowest vaccination rates.
Murupara Community Board chairwoman Jackie Te Amo said her "thoughts and prayers" were with the family.
"I'm hoping that the families inside our ward have actually got protection - that they are vaccinated."
Te Amo said health providers such as Te Ika Whenua Hauora had processes in place for the families and how best to look after them.
"I know that every iwi is doing pretty much their Covid plans inside our ward.
"I'm really impressed that everybody is pulling together."
She encouraged people to keep getting tested and if they were feeling unwell, and asked people to "think about other families" before going to "areas that you shouldn't be".
