New Zealand First hopes the Defence Force will take better care of its personnel, in the light of shock suicide figures from the Australian military.
An investigation there has found serving personnel and veterans are more likely to die of self-inflicted injuries, than on active duty.
Australia lost 41 soldiers over the 13 years it was in Afghanistan, while in the past year alone there have been 41 suicides among active and former soldiers.
Defence and veteran affairs spokesman Ron Mark said New Zealand servicemen and women are also needing support to help deal with what they've seen at war.
"I'm frequently contacted by New Zealand service personnel, or family, who are worried about somebody, who is not getting the kind of treatment, or not getting effective counselling from the Defence Force."
