Defence Minister Gerry Brownlee leaves New Zealand today for a meeting in Paris to discuss what happens to Mosul after Iraq takes control of it again.
New Zealand is not involved in any combat role in the move on Mosul, Iraq's second largest city which was seized by ISIS two years ago.
But alongside Australia it has helped to train 12,000 Iraqi troops at Camp Taji near Baghdad, and many of those troops are involved in the Mosul mission.
Brownlee said the meeting of the coalition of countries helping Iraq to fight ISIS would be briefed on the Mosul campaign but would largely be forward looking.
"If you think of Mosul of being a city with the population of Auckland plus, re-establishing civil Government there will be a big priority for the Iraqi authorities and part of that will be some of the general policing activities that would normally happen in any civil society."
