Prime Minister Bill English will not rule out a levy on new migrants to pay for infrastructure, but says any new levy would have to meet a high bar.
The proposal of a special levy was included in the New Zealand Initiative's report on the impact of immigration on New Zealand. It noted that while overall migrants had a beneficial impact on New Zealand, there was increased pressure on infrastructure such as schools, health care and roads.
It said that created pressure on local councils and Government.
English said it was an "interesting idea."
"I think the bar for any new levy is pretty high. If you're going to bring in a new levy or tax, there has to be a very good reason for it, so there would have to be a lot of discussion before we got to that point. But we certainly are committed to building the infrastructure to support the growth in population."
