Pukekohe High School and Western Springs College are the latest Auckland schools with confirmed Covid cases.
A student at Western Springs College and a staff member at Pukekohe High School have tested positive for Covid-19.
The student at Western Springs College was in class on Tuesday August 17.
However the student only attended one class on Tuesday, the school said in an email to parents.
"The student was only in school for a short time (until 10.00 am) on Tuesday August 17th," the email said.
"Parents of close contacts have been called either by myself or our associate principal. The current advice that I have received from the Health professionals is that Close Contacts are those students who were in the period 1 class with the infected student and their teacher, and will now isolate for 14 days from the day of contact.
"They will be tested on Day 5 August 22nd and Day 12, August 29th before completing isolation on August 31st."
The rest of the school's students and staff were deemed close contacts and were not required to be tested.
The Western Springs College case takes the total number of schools with confirmed Covid-19 cases as a result of the latest Delta outbreak to seven.
Earlier, Pukekohe High School emailed staff to confirm that one of its staff had tested positive for the virus.
There are also multiple cases at two Auckland universities linked to the current Delta outbreak.

The student, who has been moved to a managed isolation facility, had attended five lectures between August 11 and August 13.
