However, he refused to give a guarantee soldiers would not see combat, saying it was a hypothetical question as no decision had yet been made on the deployment. Military personnel are in Iraq assessing what contribution New Zealand could make with training -- including assessing how safe training locations are and whether there is good enough security.
Prime Minister John Key has also spoken of the possibility of sending extra help to other military operations in the region to take the place of other countries which are redeploying equipment or people to Iraq to fight Isis.
A spokesman for Mr Brownlee said no specific operations had been identified. He said it was possible New Zealand could send logistical support or equipment, such as aircraft, to pick up the slack where other countries had diverted their resources to Isis.
Mr Brownlee also dismissed suggestions New Zealand was now at a much greater risk of a retaliatory attack by Isis because of its announcement it would boost its intelligence work which can help the US identify Isis targets for air strikes.
He said the Government had weighed up the risk of retaliation by Isis but was advised the risk would not be much higher than it already was.
"Do you really think the most sophisticated terrorist organisation ever doesn't know that New Zealand is part of Five Eyes? We don't believe the threat risk is any greater as a result of this than it was."
The Green Party opposes any military role, including training, saying that by taking an active part New Zealand was effectively joining the US "war" on Isis.
