A Mt Roskill Grammar Student's father has tested positive for the coronavirus, according to a letter sent to parents by the school's principal.
The man arrived in Auckland from Europe on March 12 and attended the Tongan Fiafia event at the school that night for about an hour, the letter from principal Greg Watson says.
New rules requiring international travellers to self-isolate for 14 days were brought in several days after he arrived in New Zealand.
The man's child attended school most days following until March 19 and does not have symptoms, Watson told parents in the letter today.
Mt Roskill Grammar had sought "urgent advice" from the Ministry of Education and the Ministry of Health.
