They have passed a resolution saying global funding will undermine the equity and quality of education.

It comes after a string of meetings across the country.

More than 99 percent of teachers have voted against the funding model and are now demanding further action.

The unions representing primary and secondary teachers say global funding is a return to the failed bulk-funding experiment of the 1990s and could result in fewer teachers and larger class sizes, to the detriment of children's education.

At a media conference at Wellington's Clyde Quay School this morning, NZEI president Louise Green and PPTA president Angela Roberts confirmed there was now a mandate to take further action against global funding.

"This funding proposal has created unprecedented concern - and unity - across the education sector. Educators see no benefits but great risks to education if global funding is to go ahead," said Green.

Roberts said the Government needed to take bulk funding off the table and focus on better ways to address inequity and chronic under-funding of the education system.

The unions would continue the campaign with the launch of a roadshow starting in main centres next term. The public would asked to sign postcards to the Minister of Education rejecting bulk funding and calling for better funding.
