Iraqi Prime Minister Haider al-Abadi said his country would like a bigger contribution for longer from New Zealand troops.
He made the comments after a bilateral meeting in New York with Prime Minister John Key.
"We need all the international support possible in the international coalition and New Zealand is part of that," he said.
He acknowledged that New Zealand had extended its training of troops to help defeat Isis, or Da'esh as he calls it.
"The help and support given by New Zealand is very important for us in terms of the coverage of time we extended and in terms of the size," he said.
