Geography: Burnham, also known as Burnham Camp, is the largest army base in New Zealand's South Island. It is located 28 kilometres south of Christchurch on the Canterbury Plains in the Selwyn District, close to the town of Dunsandel. Burnham was named after Burnham Beeches, Buckinghamshire, Great Britain.
The senior headquarters at the camp has seen many changes. Previously Headquarters 3 Task Force, 3 Task Force Region, HQ Ready Reaction Force, and 3 Land Force Group have been based here. Most recently 3 Land Force Group was disbanded in 2011, and Headquarters Deployable Joint Task Force Headquarters - Land (DJTFHQ-L) was formed.
