About Sumner
Sumner is a coastal seaside suburb of Christchurch, New Zealand, and was surveyed and named in 1849 in honour of John Bird Sumner, the newly appointed Archbishop of Canterbury and president of the Canterbury Association. Originally a separate borough, it was later amalgamated with the city of Christchurch as communications improved and the economies of scale made small-town boroughs uneconomic to operate.
