"The site is not conducive for portable classrooms," she said.
Mrs Dickson was asked for her response to the ministry's plans to reduce the number of classrooms in the new Frankton school from 24 to 20.
The school would still cater for 460 pupils, as gazetted by the ministry.
The ministry's update on its approved outline plan was received by Lakes Environmental this month.
It states the third southernmost "learning pavilion" will be a single-storey block instead of two storeys, as planned for the other pavilions.
Remarkables Primary School (RPS) establishment board of trustees chairman Roy Thompson told the Queenstown Times the reason for the change was that the board recognised the design of the school allowed for a potential increase of pupils from 460 to 560 and had this put to the ministry as an option last year.
"But when the National Government announced the funding in December, the ministry decided to stick to the original model of 460."
Mr Thompson said the updated outline plan was lodged with Lakes Environmental, as the school did not need to apply for resource consent.
"It's to give the council a heads-up about what's proposed, to give the council a chance to raise any concerns or issues. The ministry is not obliged to take action, but it gives parties a chance to have a discussion."
The updated outline plan contains two further amendments to the $17.3 million development.
The single-level early childhood centre, which will house the Frankton Playcentre next year, was to be excavated into the slope of the northeast corner, with the roof "folding" over the building.
Instead, the centre has been redesigned as a more traditional above-ground structure and the four parking spaces have been moved elsewhere, away from the main entrance.
A total of 10 parking spaces under the RPS administration building have been removed.
The site will now have 30 car parks on the eastern side of the administration building, in the drop-off zone and along the Lake Ave frontage of the drop-off zone.
Lakes Environmental planner Wendy Rolls said the outline plan was on hold while the ministry works on a parking plan with the council.
The Ministry of Education did not return messages before our deadline yesterday.
