Karamu High and Hastings Boys' High were among the growing number of Hawke's Bay schools changing their academic delivery.
Hastings Boys' High sent a letter to the parents and caregivers last Friday saying the senior management team had made the decision to begin rostering home one year level each day, beginning this week, to be reviewed in Week 10.
Karamu High School principal Dionne Thomas gave a Covid update to the school mid-week, last week.
"This week we have seen a steady increase in staff and student positive cases, as well as absences for isolation," she said.
"For this reason, we have made the decision to continue the year level rostering home for the remainder of term one. We thank you for your support in this to enable us to continue to offer face to face learning for most students."
The Ministry of Health stated the increase in Covid cases was not unexpected, as there was generally lower testing and reporting over weekends.
"Getting boosted continues to be one of the most important ways people can protect themselves from Omicron and severe illness," stated the Ministry.
"There is a much lower risk of being hospitalised if you are up to date with your vaccinations, which, for Omicron, includes a third or booster dose."
