Staff have moved into the two-storeyed administration building at Alexandra Primary School, with the former office and staffroom now utilised as classroom space, principal Adele Gott said.
The new $600,000 building houses an office area, meeting room and two teaching spaces.
The former staffroom was being used by an "e-learning" class, Miss Gott said, while the former office and adjoining room would be opened up as classroom space for a boys-only class.
A new dental clinic is also being built at the school.
Due for completion in March, it will shared by the dental nurse and pupils from The Terrace School, she said.
The move is part of a scheme to centralise dental services for state primary schools in the Alexandra area.
The Omakau and Poolburn schools will be served by mobile clinics housed in buses.
A new multipurpose room at Clyde School was about three weeks away from completion, principal Doug White said.
"We've just got the landscaping and some other minor finishing detail to do. We want to make sure everything is right.
"It's a big thing for Clyde," he said of the $900,000 building.
It has a stage, room for physical education classes, a library and an information technology room.
The building would be in use by the beginning of March, Mr White said.
Poolburn School's new multipurpose room is also almost completed, principal Simon Waymouth said.
"We're in the final stretch. I'd expect us to be in there by the end of this term or the beginning of term two."
The $191,000 room will house a computer suite and the school library.
In Cromwell, construction of a new classroom at Goldfields Primary School should begin in the next few weeks, principal Sharon Booth said.
"We in the final stage of gaining Ministry [of Education] approval.
"As soon as we get that, building will start."
The room was needed as the school's increasing roll meant its library had to be shifted to a storeroom last year, Mrs Booth said.
The new classroom would bring the number of classrooms at the school to nine.
