During the War in Afghanistan, elements of the New Zealand Defence Force were deployed to Afghanistan's Bamyan Province in September 2003 as part of the New Zealand Provincial Reconstruction Team and remained there until 2012. The New Zealand PRT provided regular military patrols across the province, advised and supported the provincial governor, and participated in developmental projects. In addition, the elite New Zealand Special Air Service (NZSAS) saw action during the United States–led invasion of Afghanistan between December 2001 and November 2005.
