Iraqi troops trained by the New Zealand Defence Force were part of a force that has retaken the city of Ramadi from the Islamic State (Isis) terrorist group.
Defence minister Gerry Brownlee said the success was a result of the commitment to the Building Partner Capacity training programme.
"New Zealand and Australian trainers can take some pride over the successful action by the recruits.
"NZDF trainers have gone into a dangerous environment and professionally established a training operation which is upskilling large numbers of Iraqi troops to better equip themselves to fight.
"New Zealanders can be very proud of the work our troops are doing to professionalise the Iraqi security forces," Mr Brownlee said in a statement.
