''It's very clear that study at higher levels improves your career prospects. I encourage young people to take every advantage they can of their tertiary study opportunities to obtain the skills to compete in the modern world,'' he said.
The report, being released today, reveals a large gap in the earning power of different subjects, with medical school graduates the top earners, with a median income of $109,977 five years after they graduated and performing arts graduates earning the least, with a median income of $35,552 five years after finishing study.
Mr Joyce said the data would be used by Careers New Zealand in a new online tool allowing students to compare earnings by qualification and field of study.
''The choice of study is very much a decision for students and their families. The Government has committed to provide better information to assist in making those choices, for the benefit of students and for the very significant investment taxpayers make in tertiary education,'' he said.
This report, called ''Moving on up - What young people earn after their tertiary education'', would complement a new report from the Ministry of Business, Innovation and Employment on the demand outlook for major occupations, due out next month, he said.
