Last month, Education Minister Anne Tolley announced it was likely Macandrew Intermediate and Forbury Schools would merge as a years 1-8 primary school on the Macandrew site.
She also announced it was likely Caversham, College Street and Calton Hill Schools would also merge as a years 1-8 school on the Caversham site, with a campus on the Calton Hill site.
A large group of vocal protesters marched up George St late last month, pleading for Mrs Tolley to see the value in Forbury School and keep it open.
Forbury principal Janice Tofia said the petition began about the same time, and 7777 signatures had been collected.
"The petition calls for Forbury School to remain on site and in its entirety.
"Hopefully, it will help Mrs Tolley in her decision making, and show her there is support in Dunedin for Forbury School to remain on site," Mrs Tofia said.
Dunedin South MP Clare Curran will present the petition to the House in Wellington today.
