Labour has attacked the degree of secrecy about the preparation of a New Zealand troop deployment to Iraq.
The ABC in Australia revealed yesterday that New Zealand troops had begun training with the Australian Defence Force in Australia.
And while Defence Minister Gerry Brownlee said he had a "satisfactory agreement" with the Iraqi Government on legal protections for New Zealand troops on deployment, he said he would not be releasing it for security reasons.
A joint New Zealand-Australia mission is scheduled to leave in late May for Camp Taji, just north of Baghdad, to help train Iraqi soldiers to fight Islamic State (Isis).
Mr Goff said the level of secrecy was unprecedented and that Labour had released the state of forces agreements for peace-keeping missions in the Solomon Islands and in East Timor.
