"I've looked at the cabinet paper and to me it looks like bulk funding just with another name, and the only difference I can see is that it is coming from the centre rather than coming from the school.
"I'm really concerned because there is almost incentive for schools to employ fewer and cheaper teachers. I cannot see anything that could be beneficial to my children, whatsoever.
"What we don't want is rearranging the system to something that is going to be detrimental to children, to something that is going to have less experienced teachers in front of children, cheaper teachers on the whole in front of children and making it harder for schools to employ support staff."
Ms Tinetti hoped the discussions could turn the proposals into "something better".
"I'd imagine there would be lots of strong debate about it," Ms Tinetti said. "The way it is at the moment, I would be very, very scared about it going ahead. We're an underfunded system as it is."
Post Primary Teachers Association president Angela Roberts agreed.
"Schools are going to be in the terrible position of trying to make decisions about how to pay for the entire school to run and there will be significant pressure on them to reduce their staffing costs, both teacher aides and teachers," she told Radio New Zealand.
Teachers and parents had rejected bulk funding 20 years ago, Ms Roberts said, and she expected they would do the same with this proposal.
Tauranga principals are to meet on Wednesday to hear about the proposed changes.
The proposed changes would mean:
* Principals would determine the split between cash and credit, with the flexibility to make adjustments during the year.
* Unspent credit would be paid out at the end of the year and a process for recovering credit overspends would be established.
* Teaching staff salaries would be charged against the "credit" portion at an average rate.
* Non-teaching staff salaries would be charged against the "credit" portion at actual cost.
