Advocacy groups have criticised National's welfare reform policy with one saying Prime Minister John Key is living in a "fantasy world".
Auckland Action Against Poverty said Mr Key's world bore no resemblance to what people on the benefit were going through.
"In the real world the unemployed join queues of thousands of job-seekers to apply for a minimum-wage job at a supermarket and wait all day for an interview that has less chance of success than winning the lotto," said spokeswoman Sarah Thompson.
Child Poverty Action Group co-director Mike O'Brien said the proposal of three distinct benefits did not take into account various circumstances.
"It's very heavily reliant on the availability of jobs. The numbers on benefits have gone up because of issues around the availability of jobs."
