David "Chook" Henwood is one of the country's most decorated and respected police officers, who served for 37 years in South Auckland before retiring in 2007. He held the rank of Detective Sergeant and was awarded a record three silver merit awards during his time as an officer. Henwood was an early and, for a time, relatively lone voice in proclaiming the innocence of Teina Pora for the 1992 rape and murder of Susan Burdett - whose conviction would, 20 years later, be overturned in one of the country's most high profile cases of a miscarriage of justice.Now in his early 70s, Henwood has six grown up children and lives in Cambridge with his wife, Carolyn.
