Today's gathering of about 100 people at the Putorino School on the Waikare Coast Rd north of Napier would be a colourful get-together of several generations, principal Vivienne Wallace said.
The school, which started rural educational life as a simple tin shed, is celebrating its centenary.
"We have 88 registrations (of past pupils) and along with sponsors and guests we'll have around 100 here - which is wonderful. It's all ages," Mrs Wallace said.
"We have children here today whose parents went to Putorino School and their parents before them - there will be some marvellous stories told." The school is classed as "sole charge" as it has just 14 pupils aged between 5 and 12, although there is a support teacher and support staff.
But Mrs Wallace said it had a strong and solid community spirit driving it.
