That meant national standards, league tables, proposals for charter schools and performance pay for teachers, he said.
The meeting was the first of two this week. The second will be held at Wanganui East School tomorrow at 1.30pm.
NZEI representative Graham Whitworth said the teachers' collective agreement was in jeopardy.
"And that's at the basis of these meetings. Teachers are unhappy. They're feeling threatened because they believe the new structure will slow progress up the career path and the salary scale and they can't do anything about it.
"So many teachers are upset, which is why we're having these meetings throughout the country."
National standards "threatens to narrow our broad curriculum and treat children as 'one size fits all'," he said.
League tables encourage competition and unfairly create "winner" and "loser" schools when top performing countries ensure schools work together, he said.
"But we believe that every school should be a great school. Teachers want to teach in a fair system which allows for creativity and all students to succeed ... it's really not too much to ask."
Mr Whitworth said the fight was not just about teachers and their pay and conditions.
"They want the best for the kids and this government will destroy it all."
