UPDATED 12.41PM: The Prime Minister's office is refusing to confirm or deny reports New Zealand is about to take an extra 100 refugees.

Ariane Rummery, a spokesperson for United Nations High Commissioner for Refugees, claimed this morning on The Nation that another hundred Syrian refugees would be accepted into New Zealand "on top of" the quota of 750.

"That's a great start," Rummery said of the increase.

"And if New Zealand wanted to increase [the quota], of course we'd be very pleased."

A spokesperson for the Prime Minister wouldn't confirm the increase saying "the government is looking at all the options available and we’re not ruling out doing more across a range of areas."

"We need to take advice on that to ensure any decisions made can be backed up with the same level of support and assurances we give to other refugees that come to New Zealand."

Immigration Minister Michael Woodhouse's office claimed it was possible Rummery was referring to a previous commitment made back in February for 100 Syrian refugees within the current quota.

Of that number 83 are already in the country, while 17 are yet to arrive. 

The global refugee crisis is the worst since the end of the Second World War, with European nations scrambling to address the influx of people fleeing from war-torn nations like Syria and Iraq.

Despite the crisis, New Zealand hasn't raised its quota for refugees above 750 in nearly thirty years. Political and public pressure is building on the government to allow an emergency intake, and a doubling of the quota. National's support parties ACT and United Future are backing a rise.

Both the Labour Party and The Green party yesterday said that they would be trying to table their own bills next week over the matter.

Green Party co-leader James Shaw believes that even an extra hundred won't go far enough.

"If you look at the scale of the challenge, it is quite pathetic really," Shaw said.

Action Station, a website which campaigns on various issues, has gathered more than 14,000 signatures on a petition directed at Immigration Minister Michael Woodhouse, calling for another hundred Syrian refugees to be given space in NZ, over and above the current quota.

A Facebook page called Doing Our Bit - Double NZ's Refugee Quota has garnered over 5000 'likes'.

Another page 'Open homes - Open borders' has been set up by activist Urs Signer, asking people whether they have a spare room, sleep out or bach to offer refugees.

Tracey Barnett, author and founder of refugee awareness initiative WagePeaceNZ, believes the growth in support online is indicative of the welcoming nature of New Zealanders.

"What we're seeing is that our government is sadly out of step with what is the greater feeling amongst average New Zealanders, which is that we want to do more, we can do more," Barnett said.
