with no earning gain - study
Their study, He Awa Ara Rau, tracked education and employment of 76,000 Māori to age 25.
It found 18 percent got tertiary qualifications at levels 1-3, but those courses did not lead to higher incomes and better job prospects.
The study said even those who achieved NCEA level 2 at school and completed a level 3 certificate at a tertiary provider would have been better off staying at school.
"A disproportionate number of rangatahi leave school after completing NCEA Level 2 to go on to Level 3 certificates at PTEs [Private Training Establishments]. Unfortunately those that do will earn significantly lower wages by age 25 than those rangatahi who stayed longer at school," the report said.
It called on the government to stop funding such courses.
