New Zealand troops will be pulled from Afghanistan after a 20-year presence in the country.

Prime Minister Jacinda Ardern announced this morning that the deployment - which currently includes six Defence Force personnel - would end by May.

"The deployments to Afghanistan have been one of the longest running in our history, and I wish to acknowledge the 10 New Zealanders who lost their lives in the line of duty, and the more than 3500 NZDF and other agency personnel, whose commitment to replace conflict with peace will always be remembered," Prime Minister Jacinda Ardern said.

The six NZDF personnel currently in Afghanistan are three people deployed to the Afghanistan National Army Officer Academy, and three deployed to the NATO Resolute Support Mission Headquarters.

Foreign Affairs Minister Nanaia Mahuta said that although the environment remains complex, the intra-Afghan peace process affords Afghanistan the best prospect of an enduring political solution.
