Mayor Wanden said the school was originally to be called Highlands Primary School, and that many of the street names in the area - Heather, Skye, Solway, Braemar, Kinross, Strathmore, Cargill - were Scottish in origin.
Wanden said it was fitting that sense prevailed and the school was christened Taitoko, a name with more relevance as it was the original name of the area given by Māori.
One of the oldest students, John McIvor, cut the memorial cake with one of the youngest, Noah Pritchard.
The reunion was organised by a committee headed by Wendy Morgan and Maria Putu. Former staff that attended were David Lewis, Zona May, Gloy Deadman, Sue Kyle, Ann Goodwin, Ann Garvey, Donna Price, Paula Westerby, Paula Sasa-Masters and Wendy Morgan.
The reunion was two years in the planning.
