Ardern hopes the $2000 Vocational Excellence Award for top students would get more students into these professions.
"It will, I hope, send a strong message about the value this Government places on vocational education and encourage new generations of students and their families to recognise the exciting opportunities it presents."
She is encouraging secondary students to apply as soon as they can so schools can include the award in this year's prize-giving ceremonies.
Vocational education is learning that has a special emphasis on the skills needed to do a specific job, or work in a specific industry.
The announcement comes after the Government launched its reform of the vocational education system.
Last week, Education Minister Chris Hipkins announced that all 16 institutes of technology and polytechnics in New Zealand would be brought under a single national institute, the NZ Institute of Skills and Technology, which will start on April 1 next year.
Centres of Vocational Excellence (CoVEs) will be established at regional campuses to drive innovation and expertise, and improve links between education, industry and research.
Hipkins said vocational education, trades training and on-the-job training have been allowed to drift for too long.
He said the Government's move would strengthen the vocational education and training system and help it to respond better to the needs of New Zealand learners and employers.
"These are long-term challenges that this Government is committed to fixing."
