After about 40 years this Intermediate School was closed due to a falling roll. The school was named after a former Christchurch mayor - George Manning. Manning was born in Gowerton, Wales, on 11 February 1887. He was the son of Richard Manning (steelworker) and Sarah Davies. Together with a friend, he emigrated to Christchurch in 1910. He married Scottish-born Sarah Edith Willmore at the Trinity Congregational Church, Christchurch Central City, on 11 October 1923. He served as Deputy Mayor from 1950 to 1958, and was elected as Mayor in 1958. In the 1968 election, he did not stand as a candidate again.
Since then the school has been rebuilt and is now Spreydon Primary School.
