PPTA president Robin Duff said the association were pleased with the level of response to the advertising campaign.
He said 1000 submissions had been generated in 10 days.
"It shows the New Zealand public is deeply concerned about the shoddy way this seems to be driven through ideologically without proper consultation."
NZEI vice president Frances Guy said the response to their campaign had been positive.
"Parents, schools and communities are all saying they don't want charter schools. Outside of the Act Party, there is almost no support for this legislation."
Mr Duff has called for the education and science select committee to travel to Auckland and Christchurch to hear submissions.
"We'll be watching carefully how the five National MPs on the committee respond to these submissions as they are responsible to the voters and young people of New Zealand," he said.
