It is the third time the college has resorted to the roster system.
Principal Ross Preece said it was with regret the college was rostering students home, starting with year 11 from Friday.
Year 12 students will learn from home on Monday, year 9 on Tuesday, year 10 on Wednesday and year 13 on Thursday.
Following this, rostering home will be reviewed every two days, Preece said.
"This action has not been taken lightly and is in response to an acute staffing shortage."
Preece said students will have access to work to complete via Google Classrooms, or hard copy, for their scheduled days home.
"Keeping up to date is vitally important so students can attain the credits as NZQA have indicated they will not be offering learning recognition credits as they have done over the last two years."
He said external courses such as Gateway, Ara, and work placements will still run as usual, even if it is a rostered day off. Senior students may be able to come on site and work with available staff if pre-arranged.
The parent, student, teacher interviews on Tuesday are going ahead as planned, and Preece called for understanding if staff were unwell or unable to attend.
"An e-mail will be sent to you prior to interviews if this is the case.
"All staff will be wearing a mask (unless a mask exemption applies).
"Mask wearing for parents and students is strongly encouraged (a supply will be available at the door)."
The Burnside sports exchange planned for Tuesday will also go ahead.
