The Special Air Service officially ends its operations in Afghanistan today and is unlikely to return.
New Zealand's elite force has been mentoring Afghanistan's Crisis Response Unit in the capital Kabul since 2009.
The unit is responsible for dealing with insurgents.
It is the fourth and longest deployment the SAS has been on in the war torn country.
During the deployment, two members of the unit have been killed and the SAS has been involved in dealing with a number of high profile insurgent attacks.
Prime Minister John Key says it is not his expectation that the unit will go back to Afghanistan.
