However, the New Zealand Aids Foundation (NZAF) has disputed this, labelling the care plan a strategy to shut out the boy.
The Trust is now preparing to take legal action over "untrue'' claims made by the Aids Foundation, which Ms Tipene said were an attempt to boost its funding.
"It's more lies by the Aids Foundation. They've had their funding cut dramatically and this is a deliberate strategy to increase their profile.
"Our centre and our families have been demonised. We're preparing to take legal action.''
She said a care plan was necessary for any child with a health issue that required extra help.
NZAF spokeswoman Dawn O'Connor said there was no need for a care plan because the level of virus in his blood was so low it could not be detected or transmitted to other children.
"It's not a care plan, it's not a caring thing to do, it's a strategy to keep this child out.''
The boy is due to start Whau Valley Primary School in July.
A meeting between the school principal, staff, and the boy's parents was held today to "clear the air'' and educate them about the facts of HIV, said Ms O'Connor.
