There's been an 11 percent rise in the number of people who want fewer immigrants in a poll.

About 38 percent people want fewer migrants let into New Zealand, according a Colmar Brunton poll for TV One, up 11 percent from April.

About 44 percent think the current level of immigration is about right, down from 51 percent in April, and 13 percent want more migrants let in, down from 18 per cent in the previous poll.

Net migration figures have soared to record highs in recent months, with a gain of about 69,000 people in the year to July - compared to an average of about 21,800 a year over the last decade.

Immigration Minister Michael Woodhouse has said the numbers reflected a large number of Kiwis coming home.

He said the government planning range of about 45,000 to 50,000 new migrants a year would be reviewed in the next month or so.
"I don't think it will change materially," he said.

Mr Woodhouse said while he was aware there was a risk wages could be suppressed by migrant workers, he had not seen any evidence of it occurring.

The Reserve Bank and Treasury have both expressed concern that increasing migration could be keeping wage growth down.
