The troops had been part of the Building Partner Capacity mission, training Iraqi security forces, and were based at the Taji Military Complex north of Baghdad.
In April last year, the first rotation was deployed, with more than 100 New Zealand forces being deployed to Iraq alongside soldiers from the Australian Defence Force.
The training provided by Task Group Taji covered weapons handling, combat first aid, live fire training and drills in complex war fighting environments. Other specialised courses provided lessons on map reading, use of the Global Positioning System, marksmanship and leadership, among other topics.
Iraqi soldiers were also taught the fundamental aspects of international humanitarian law and the law of armed conflict.
