The reallocated and refurbished classrooms and new access pathways are ready for the first term of school to start next week.
The work will ensure that the school operates with minimal disruptions during the construction period.
In November, a previous government residence adjacent to the school was refurbished and an outdoor learning area was built alongside it.
These buildings will accommodate Maori and Culture until more learning spaces become available.
Behind the refurbished house sits the Food Technology building which was relocated earlier last month.
Contractors created a covered outdoor working area, giving students much needed space to work under.
Two classrooms that were consumed by a fire in August last year have also been restored.
These will be used to house Physical Education (theory), Health and Social Studies.
Year 8 students of Apii Nikao will recombine with the rest of the school after spending one year at Tereora College.
A transportable building is being constructed on the south field of Apii Nikao. It comprises of two internal learning spaces, an outdoor learning area and toilet facilities.
These classrooms will accommodate senior students until the Apii Nikao Rebuild project is complete.
When students move into their new school, the building will be relocated to another school or government property where it may be repurposed as needed.
School movement and traffic management plans are now active. For safe transition between the upper and lower quads during the construction period, a walkway has been built on the southern bank of the BCI stadium.
When Stage 1 is complete, it will serve the stadium as an accessible route for people who are physically challenged.
A pick-up and drop-off zone for buses has been allocated at the rear of the Princess Anne Hall.
Student and staff parking will be provided at the front of the school near the Ara Metua.
