PM says that if US asks for help, he can’t rule out sending troops to Iraq or Syria.

New Zealand's elite Special Air Service (SAS) personnel are not yet on standby for deployment to combat Islamic State militants in Iraq or Syria, Prime Minister John Key says, but he won't rule out sending them if asked "as a last resort".

The US State Department has named New Zealand as one of more than 60 countries in the coalition supporting its efforts to counter Isis (Islamic State) but Mr Key yesterday said he hadn't yet received any requests for assistance.

However, he said that was probably partly because his Government hadn't yet been sworn in following this month's elections.

Asked whether he would send military personnel if requested, Mr Key said: "I can't rule out that there won't be because what you can see around the world is countries being asked to give support."

As far as sending SAS personnel, Mr Key said: "I can't rule that absolutely out, but what I can say is that I'll get advice and we'll see how that goes, but it would be my least preferred option."

Any commitment of personnel "would be a step I think we should take very cautiously and with our eyes open because history tells you that going into places like Iraq is fraught with difficulty and danger and as we know with Afghanistan, it was a very long-term commitment".

Afghanistan had shown such commitments were neither easy nor shortlived and the sophistication of Isis was greater than the al- Qaeda-linked Taliban there.

"These are not insignificant people. Their acts of brutality are grotesque and most New Zealanders would be deeply offended by what they see."

Mr Key said the SAS, who had intelligence gathering and training roles in Afghanistan, were not on standby for deployment at this time, but 3 News last night reported that a squad of 12 SAS personnel were in "pre-deployment mode" for a possible mission in Iraq.

Mr Key again emphasised that involvement in Iraq, where the Government had asked for international help, was more likely than in Syria, where that was not the case.

Despite his clear reluctance for New Zealand to get involved in military operations, Mr Key said he was of the view that airstrikes on Isis targets "will only take you so far".

He was also taking advice on whether New Zealand would follow Australia and begin publicly notifying its threat level.
