Mr McTamney said it was great being back in the school and seeing the progress it had made.
"As a former principal it is marvellous to be able to come back and see how well the school is doing. Malfroy School is child-orientated, progressive, inclusive and delivers wonderful educational results."
He said the turnout for the reunion celebrations had been wonderful and the theme of "togetherness and reflection" had served them well.
"All in all I am very pleased with how it has all come together."
Principal Nicky Brell said the reunion had been 12 months in the making.
"The event has been a great success in two ways - the number of people who attended and the information that we have been able to get from the school archives. The production of a reunion booklet has just been the icing on the cake."
Councillor and former Malfroy School pupil Charles Sturt said he had loved going to the school and had great memories of the teachers.
"[Taini] was my first teacher in 1961. I had lots of great teachers including Mr Peach, Mr Green and Mr Ludgate. It feels quite nostalgic being back here celebrating the school's history and place in the Rotorua community."
