The earthquake evacuees have been enrolling since last Wednesday, taking the roll to 480, an increase of 23%.
Elsewhere in the town, Mt Aspiring College's roll has jumped 19% from 691 to 821.
Wanaka Primary School is new and has been able to cater for the unexpected influx because it was built with roll growth in mind, but Mt Aspiring College is operating at maximum capacity.
Wanaka Primary School principal Dr Wendy Bamford said the rate of new evacuees was dropping, with just six enrolments yesterday compared with 63 last Friday.
"They are still coming in, although some are saying they are going home to test the water this weekend. But quite a number more are on our books to come next week," Dr Bamford said.
The school has not integrated the Christchurch children into classrooms with their Wanaka peers because it was felt the increase in numbers would have been unsettling.
The pupils have instead been put into "Christchurch" classes.
There is one class of year 1 and 2 children (20 pupils), two classes of years 3 and 4 children (18 and 25 pupils respectively) and two classes of years 5 and 6 children (25 in each).
Other staff, including those in library and office administration work, have had their hours increased to cater for the new pupils, Dr Bamford said.
Teachers Ruth Mayne, formerly of Te Puke, and Jason Cowan, formerly of Dunedin and Wellington, are among the new recruits.
Mr Cowan said he had been job-seeking and was thrilled to be working with year 5 and 6 Christchurch children.
"I got the call at 3pm on Friday last week - "do you want to work?" - and I started first thing on Monday.
"They [the new pupils] are loving it here, absolutely loving it. It's amazing how resilient they are," he said.
Mt Aspiring College deputy principal Greg Thorton said while the situation was fluid, many of the new pupils had indicated they wanted to stay for some time.
New pupils were being integrated into existing classes as much as possible. Schedules had to be adjusted slightly for some of those who had nearly completed NCEA modules.
