Cabinet consideration of the budget for any construction will not happen until after the election, most likely in November and December.
Ms Mandow said the ministry had gone quiet on what options it would present. She has asked parents to lobby local politicians to ensure the pressure remains for a proper rebuilding.
Western Springs College is a co-ed state school which draws students from Auckland City, Ponsonby, Grey Lynn, Freemans Bay, Pt Chevalier and Westmere.
Last night Associate Education Minister and Auckland Central MP Nikki Kaye said the ministry was gathering further geotechnical and structural information and a business case would be developed in consultation with the community. Ms Kaye, who planned to meet the parent action group, said advice was the cost could be at least $50 million.
Principal Ken Havill said he could understand the community's frustration but various issues had meant the project had taken time. It's expected construction would start in July to December 2016, with new facilities ready by January 2017.
Mr Havill said he expected the options eventually presented by the ministry would be versions of a comprehensive rebuilding.
MP for Mt Albert David Shearer, who has a daughter at Western Springs College, said numerous people had contacted him with concerns, and he was due to meet Mr Havill today.
