Labour leader Andrew Little says any unfairness in Labour's scheme for three years of free tertiary education will only be short term and is required for it to be affordable.
Mr Little visited Millars Electrical in Wellington today to start the sales pitch for his policy, which will give first-time tertiary students three years of education without having to pay fees.
The policy is expected to cost $1.2 billion after it is rolled out over three years.
Mr Little has claimed it is for those who are required to change their careers in mid-life but it will be available only to first-time tertiary students, such as school-leavers and those who have had no tertiary education.
He denied it was unfair that some people would be attending courses for nothing while others had to pay. "There will be situations like that, I'm sure. But we've kind of got to get through that when we're putting in place a system we want to be around for decades after that."
