The men had worked with the army in Bamiyan, Afghanistan, and had since settled in New Zealand.
In 2010 Mr Ahmadi was wounded in the same ambush in which Kiwi soldier Lieutenant Tim O'Donnell was killed.
Major General Gawn said the medals represented an invaluable contribution to the army.
"It really does reflect the gratitude for the service all of our Afghan interpreters gave, not just to the defence force but to New Zealand."
Mr Hussaini was visibly emotional when he received his medals, saying: "It's a great pleasure and an honour for me. Thanks a lot to the people of New Zealand."
After the medals were received, the interpreters and their friends and families danced to traditional Afghani music while a crowd looked on and cheered.
Yesterday they watched their home country face off against the Black Caps at Napier's McLean Park.
