Past pupils, families, friends and teachers are gathering for a weekend of fun and nostalgia to celebrate 50 years since the opening of McKillop College.
The Rotorua girls' college was founded in 1966 and amalgamated with Edmund Rice College in 1987 to form Rotorua's first co-ed Catholic high school, John Paul College.
The celebrations start today with a welcoming ceremony, registration and presentations from guest speaker Ann Somerville. The rest of the weekend is packed with entertainment, games and photos before wrapping up on Sunday.
Reunion organiser and foundation pupil Beryl Harris said the jubilee celebration had been in the pipeline since the committee held its 40th reunion.
"It has always been part of the plan, ever since we decided at our 40th reunion that we wanted a jubilee celebration.
