But that was not a solution Mr Leckie said.
"It might delay it a bit and then it will all happen."
The union leaders and principals present said they were willing to talk to the Government about how to make savings in the education sector.
The organisations as the meeting were:
# the primary teachers' union NZ Educational Institute, president Ian Leckie;
# the NZ Association of Intermediate and Middle Schooling, president Gary Sweeney;
# NZ School Trustees Association, president Lorraine Kerr;
# the secondary teachers' union the Post Primary Teachers Association, president Robin Duff;
# the PPTA Secondary Principals' Council;
# New Zealand Principals' Federation, president Paul Drummond;
# Secondary Principals' Association of NZ, president Patrick Walsh.
Meanwhile, Labour leader David Shearer has called on the Government to ditch its plan to increase class sizes and to stop trying to make trade-offs with our children's education.
"A moratorium just doesn't cut it, " he said.
"It's wrong to try and make trade-offs with our children's future by supposedly putting money aside to improve teacher quality at the expense of increased class sizes. This will damage our children's learning."
Labour would reverse the plan in Government.
"It's about priorities. If you're looking to save money, perhaps you don't give a private school like Wanganui Collegiate $3 million in extra funding. It's marketing itself as having smaller classes and is offering parents a fee reduction."
