Education Minister Hekia Parata has indicated some education initiatives will lose funding in the Budget.
She says the Ministry of Education is reviewing its programmes and those that do not measure up are being cut.
Ms Parata made the comments on Wednesday morning after announcing an increase of more than $80 million over four years to improve student behaviour and support school trustees.
Teacher unions are worried that the Government will axe initiatives without checking first with teachers and principals.
However, they are happy that the announcement included $64 million over four years to extend the Positive Behaviour for Learning scheme to more schools.
The programme helps schools develop a positive culture and includes training for teachers and parents. It is already in use in 400 schools and another 200 will be included.
There is also an increase of $14.5 million over four years for training and support for school trustees, while $2.5 million will be spent on improving connections between schools and communities with early childhood education services.
The Budget will be delivered on 16 May.
